			<content:encoded><![CDATA[<p>A month after my last journal entry, and the day after the first<br />
killing frost, I sit down to an account of late September in the Far<br />
end of the Great Alder. This is the oft-described &#8211; in my books and in<br />
this journal &#8211; shrub swamp compartment to which many spotted turtles<br />
retreat for the winter. This niche serves as the overwintering zone of<br />
more spotted turtles than any other I have been able to discover in my<br />
Digs history. But I have not pushed the boundaries of my search-areas<br />
much in some years now. With three consecutive days of high-August<br />
weather the last week of September I came here in hopes of having one<br />
more spotted-turtle sighing for the year. I have had sightings in<br />
October and even in November in past years, but the spotted turtles<br />
rarely show themselves as August deepens and autumn comes on. Leaves<br />
had thinned considerably in the alder and winterberry thickets, but<br />
the lush growth of the royal fern mounds, though going to tawny and<br />
umbery browns, and sweeps of ochre and gold tussock sedge and reed<br />
canary and bluejoint grasses continued to make searching difficult.<br />
In great contrast with the situation here at thaw, when the vegetation<br />
has fallen away and been pressed down by snow and ice, and the turtles<br />
are compelled to take the first sun of another active season, they<br />
seldom bask at   the onset of hibernation, and are rarely on the move<br />
in the narrow channels. There is little likelihood of seeing and<br />
stalking a turtle up for some final sunning; my predominate strategy<br />
consists of shifting to sites in which I can survey some sections of<br />
channels, settling into a motionless vigil, lodged against alders,<br />
screened by fern and sedge, and waiting and watching for a quarter to<br />
half an hour, then relocating to watch from another coign of vantage.<br />
I do this at thaw also, but mix this with slow moving searches and<br />
stalking of turtles sighted on basking mounds. Great work if you can<br />
find it &#8211; how many times over so many seasons have I pursued these<br />
annual rituals cum rites.</p>
<p>On the middle day of the three, 27 September, I braced myself against<br />
alders, standing mid-thigh deep in the mud, sunken leaves, and water<br />
(the latter generally 8&#8243; to a foot deep), with a spray of reed canary<br />
grass in front of me. I could see into ten feet or so of channels to<br />
my left and right and, straight ahead. Not many sites in this terrain<br />
of the spotted turtles allow such an extended vista.  A turtle-watch<br />
in autumn is quite different from a hawk-watch. I had determined this<br />
to be my final stake-out of the visit; but that decision is frequently<br />
re-visited before actual departure. For twenty one minutes, nothing<br />
but the slow, mesmerizing drift of clear water, and occasional, very<br />
occasional, flickers of movement on the surface caused by water<br />
striders or backswimmers &#8211; there is little visible invertebrate life<br />
in this habitat element. I see little evidence of a food chain that<br />
would support the spotted turtles during their active season &#8211; they<br />
come here for the winter, and as soon as things warm up enough at<br />
thaw, move outward to far richer feeding grounds, such as the Swale.<br />
Such habitats also serve as their mating grounds. Then, on that twenty<br />
first minute, a sudden brief trembling of the surface of the channel<br />
directly ahead of me. Very brief indeed, but it was certainly a<br />
movement caused by a turtle, at the farthest extent visible to me.<br />
And in this sector of the Far End I have only seen spotted turtles.<br />
One can only be patient, motionless, and hope for a clearer sighting,<br />
a better bearing on the turtle&#8217;s precise location and movement, and<br />
hopefully a closer approach by the turtle. And in this sector of the<br />
Far End I have only seen spotted turtles.</p>
<p>Then came a flash of yellow spots, black shell, in a thin shaft of<br />
sunlight penetrating the channel &#8211; the water is clear, but is seen as<br />
black almost everywhere but where the sun strikes into it. I knew any<br />
sighting would be stunning &#8211; it has always been for me &#8211; and under<br />
these seasonal ambient and habitat conditions the rush is especially<br />
intense. And it is nothing less than a rush, even after six decades of<br />
experiencing it.   To heighten the already heightened, my fleeting<br />
vision of the turtle indicated that it was a juvenile, or subadult.<br />
With spotted turtles, this has been the rarest of the rare. I am<br />
certain that some hatchlings orient here from nearby sparse shoulders<br />
of a hayfield, where several spotted turtles nest each year, that some<br />
niches within this niche serves a nursery role for the species. I have<br />
made dedicated searches for hatchlings and juveniles where the<br />
microhabitat would appear to favor them, or they favor it; my one find<br />
being a three year old, in August several years ago.</p>
<p>The debate at this point is whether to make a rush to where the turtle<br />
appears to be, and risk his disappearance, which can occur all but<br />
instantaneously in this habitat &#8211; selected largely for that reason, or<br />
wait for that closer approach, better bearing. Then came more<br />
movements on the surface, more rapid &#8211; the turtle could have seen me<br />
and was perhaps taking flight. I tracked the surface disturbance with<br />
my eyes, trying to compute where the turtle was heading, and made my<br />
move. Not easily done in this compressed but difficult and spotted-<br />
turtle-favoring world: my feet become almost rooted in the mud when I<br />
am in one place so long, the criss-crossing of alder branches and<br />
soft, sinking substrate constrain forward, or backward or sideward<br />
advances. Three awkward strides brought me to within reach of where I<br />
thought the turtle was. A glimpse of the little spotted shell proved<br />
my determination wrong &#8211; the turtle had shifted to the right side of<br />
the channel, not the left&#8230; the channel is only a foot wide, but that<br />
narrow margin, little distance, is enough to cause me to come up empty<br />
handed. But with that one more vision I thrust blindly to the re-<br />
adjusted site and felt my hand come in contact with and close over the<br />
shell of a splendid five year old spotted turtle.</p>
<p>I documented the turtle in my notebook, made tiny identifying notches,<br />
and set him on the edge of an alder mound at the capture site. He was<br />
in the water and out if sight in what seemed a nannosecond. It is not<br />
likely I will see this one again in this dense, ultra-concealing<br />
habitat. But perhaps in five years or so, if I am yet able to be at my<br />
swampwalking,  and the young turtle begins the migratory ways of his<br />
kind, I will find him in the Swale.<br />
Or (remotely) possibly here again. In any case, I marked the location<br />
with a strip of surveyor&#8217;s tape with &#8220;5 y.o. Cg. 27 Sept 2011&#8243;. The<br />
blaze tape is not easily discernible among lingering leaves of red<br />
maple saplings and the scarlet winterberries; but when I return in<br />
spring for those beginning of the season searches and vigils, it will<br />
be evident in the gray maze of the branches and let me recognize this<br />
precise place. I returned the day after this signal finding to repeat<br />
my search regimen &#8211; no turtle seen. Unless there is a several-day<br />
truly mild spell (temperatures in upper 60s and 70s) it is not likely<br />
I will come back here until thaw, when I will likely have to make my<br />
way on snowshoes and wear neoprene, not gore-tex, waders.<br />
                                                                                                                                  * * * * *</p>
<p>In early October the Team of Four from Tufts U.,  Molly, Laura, Jeff,<br />
and Jay returned to complete  video-recording me for a documentary<br />
they will enter in an Environmental Film Festival at Tufts (by<br />
coincidence, one of my alma maters, along with the School of the<br />
Boston Museum of Fine Arts). They were responsive, stimulating,<br />
thoughtful, insightful, terrific to work with.  They want to do a<br />
piece on wetland preservation vs. development issues, and want to have<br />
me serve as the main voice. This was an honor for me and another<br />
opportunity for me to put forth the turtle Party Line, the main, if<br />
not sole, mantra of which is the call to go beyond stewardship and<br />
even conservation to preservation, preservation as in true ecological<br />
sanctuary, &#8220;exempt from publik haunt&#8221; (my oft-repeated quote from<br />
Shakespeare), independent of human service. This call is leitmotif of<br />
FOLLLOWING THE WATER, my last book, which has brought me responses<br />
from people who find it too sad to read, and others who feel I am<br />
declaring their conservation work to be in vain. As I state in the<br />
book, I do value such efforts, and recognize the sacrifice and hard<br />
work involved in conservation initiatives, but have to say I see a<br />
grievous lack of places that are established for ecosystems and<br />
biodiversity first and foremost, as opposed to becoming human theme<br />
parks, playgrounds. This is a theme I may address in winter writings<br />
here. I begin to turn to my &#8220;indoor season&#8221; of drawing and painting,<br />
writing, and language study. I will likely make a few more streambank<br />
searches for late-season wood turtle sightings, but I am now almost<br />
exclusively in my east and west Arbeitzimmer, workrooms of the above<br />
mentioned winter pursuits.</p>

			<content:encoded><![CDATA[<p>In mid-August I returned to the vernal pool in which I had found<br />
abundant salamander egg masses attached in a linear fashion along the<br />
many branchings of a limb that had fallen into the pool, when I was<br />
conducting surveys with Colin Nevins as he documented and journaled<br />
about his family&#8217;s 36-acre woodlot for his senior project at Proctor<br />
Academy. I believe I wrote a description of this in a posting from<br />
that time in the season&#8230; the egg-mass-lined branches made me think<br />
of branchings in a coral reef. I had never seen such an abundant<br />
aggregate, nor such a style of attaching egg masses. These depositions<br />
were clearly not the work of the spotted salamander (Ambystoma<br />
maculatum) and I at once felt pretty certain that this was a pool<br />
heavily favored by a substantial population of Jefferson salamanders<br />
(Ambystoma jeffersonianum).  My adult grandsons Ricky and Michael<br />
Couture live on a property that abuts the Colins&#8217; woods, not far from<br />
this particular vernal pool. In mid-August the three of us ascended<br />
the steep, boulder-studded upland rise that led to where the pool is<br />
situated, to see if we might net a salamander far along enough in its<br />
development to allow a positive identification as to species. As I<br />
kept surveillance over a sunlit patch of the pool I saw a tiny larva<br />
swim along just beneath the surface, and managed to net it. It had<br />
large gill fringes, no sign of limbs; it was too early in its<br />
development to allow a certain identification to species &#8211; at least to<br />
me. We decided to bring it back to Ricky and Michael&#8217;s house and see<br />
if we could raise it to the point of an identification.</p>
<p>By mid-September the little salamander had developed enough to reveal<br />
itself as all but certainly a Jefferson salamander. It was overall a<br />
grayish color, not very dark, and had a dusting of minute, barely<br />
discernible spots lining the very edge of its ventral surface. It<br />
still had gill fringes, and only very tiny legs had appeared. Although<br />
I now had no doubt as to the species that had committed those egg<br />
masses at thaw, I wanted to return to the pool to see if larvae were<br />
still present and if we could find one even farther along towards<br />
metamorphosis. The pool is surrounded by rocky outcrop and dense<br />
hemlocks and is deeply shaded. It was virtually impossible to see into<br />
the dark water except where slender shafts of sunlight penetrated it.<br />
We waded in and stood watch at these narrow, slowly shifting beacons.<br />
Finally Michael saw a larval salamander surface for a bit of air and<br />
descend, an action so swift in passing that he did not have a chance<br />
to attempt to net it. At least we knew that they were still in the<br />
pool; I had expected as much as the shaded water was still quite chill<br />
and and deep, and metamorphosis would likely be a comparatively<br />
lengthy process. We waited some time, without any further sightings. I<br />
decided to make random sweeps through the thick sunken leaf litter,<br />
and on my second trial I netted a larval salamander that was<br />
indisputably a Jefferson. It still bore gill fringes, though they had<br />
diminished, and the larvae were transitioning to air-breathing. I hope<br />
to return to this pool at breeding time next year to see of I can get<br />
a feeling for how numerous the adults are here. I have found pools<br />
with Jefferson salamander breeding in this region, but numbers of<br />
adults ranged from half a dozen to eight &#8211; quite a contrast to the<br />
numbers of spotted salamanders in the same and neighboring pools. (In<br />
SWAMPWALKER&#8217;S JOURNAL I describe a quite small pool that supports<br />
breeding by both salamander species, as well as wood frogs, and how<br />
they select different parts of this very restricted breeding habitat<br />
for their egg deposition.) It is also of interest that there appears<br />
to be little or no breeding by spotted salamander in this vernal pool,<br />
something I&#8217;d like to get a more certain documentation of.</p>
<p>In recent weeks, as I have continued my daily juggling of drawing,<br />
writing, language pursuits, life in general, and time in turtle<br />
places, I have concentrated on sojourns in my long-familiar wood<br />
turtle habitats. I have not come upon any more hatchlings &#8211; the time<br />
of their nest-to-water journeys is long past now, unless there is an<br />
extraordinary case (and one never knows). I have found no further<br />
evidence of hatching and believe that the exit hole I found was the<br />
only successful nest of the season. This leads me to the conclusion<br />
that the second hatchling I found, on the journey, came from that same<br />
nest, in which I found the first hatchling still lodged in the nest<br />
chamber.  I will devote myself to one final thorough search of all<br />
known nesting niches one more time before snow falls, to see if I<br />
might find another exit hole &#8211; they keep their form into winter and<br />
even beyond, and can provide hard evidence of successful nests.<br />
Eggshells of pipped or failed eggs, and any hatchlings who died in the<br />
nest, provide clutch sizes and the survival figures for the nest.</p>
<p>In the main I am making searches along the ecotones between tree lines<br />
and mown hayfield, and interior alder swamp, etc., habitats for<br />
terrestrial wood turtles. Some may well have begun to relocate closer<br />
to the banks of the two brooks in which they will overwinter, and even<br />
entered the brooks themselves; but there are wood turtles yet keeping<br />
to terrestrial niches.I returned from a search along one of the highly-<br />
favored swaths of dense grass, sedge, forb, and shrub between the tree<br />
line and the far end of the hayfield just before sitting down to this<br />
writing. Two days of rain and drizzle, and warm, humid &#8211; steamy &#8211; air<br />
preceded today, which became all the more rain-forest-like with a<br />
thinning of the cloud cover and occasional brief appearances of<br />
sunlight. Such a high-summer spell in early, or even later, autumn,<br />
seems to be something I can count on in this region&#8230; maybe a Latin<br />
American summer before an Indian summer. Such a weather pattern can<br />
delude me; I need to glance at the calendar and remind myself of the<br />
season&#8217;s overall, inevitable progress. I wanted to have a wood turtle<br />
encounter, and was favored with one. Another feature of the tropical<br />
bearing of the day was a steady, numerous accompaniment of mosquitoes.<br />
There has been a resurgence of them in the northeast following the<br />
deluges of hurricane/tropical storm Irene and subsequent remnants of<br />
tropical storms. Mosquitoes are more of an affliction now than they<br />
have been at any previous time in the year. My reward was finding a<br />
long-familiar female who was an adult when I first came upon her and<br />
is no doubt an older turtle, at least in her mid-forties. She has a<br />
distinct configuration of her carapace at the right shoulder area,<br />
with marginals sweeping up and outward, and what appears to be a long-<br />
healed narrow gash penetrating to the edge of the seam of her first<br />
and second pleurals. It is likely that this is the result of an injury<br />
caused by haymowing equipment, something I have noted with a fair<br />
number of wood turtles here. And for reasons that escape me, such<br />
mechanical wounds seem all but invariably to occur at that right<br />
shoulder area and slanting across the carapace and down toward the<br />
posterior end.<br />
She has intact limbs, only a modest tail-nip, and is one of those<br />
nesting matriarchs of the colony.</p>
<p>On the 10th of September, following a chill night with temperatures in<br />
the low forties, I went out as the sun appeared and reached favored<br />
terrestrial niches of the wood turtles to see who I might find. This<br />
is generally a rewarding strategy as the turtles move to where they<br />
can warm up after such a night, so I time the sun and search the<br />
places where it first strikes the earth. One such niche is a small<br />
corner of dense Bromus grass that is left uncut in the haying. In<br />
times past I have found turtles here regularly at certain times in the<br />
active season, including high summer. There is a narrow border of<br />
sweetfern, the second-growth forest with a dense canopy and no<br />
understory, an open floor that wood turtles eschew, that descends a<br />
long steep slope to the brook. I found a familiar 12-14 year old<br />
female at the very edge of the dense grass, well-hidden, but receiving<br />
the sun fully on her shell. At first I was not sure why there was but<br />
one identifying notch on the carapace of a turtle this young, but then<br />
I noticed that she had five left pleural scutes instead of the normal<br />
four. That anomaly and the one notch would be enough to identify her.<br />
Eleven days and half an hour later, on a morning following a narrow<br />
escape from frost as the temperature fell to 34 degrees, I found her<br />
in the exact same spot, again. The sun&#8217;s rays had recently reached it.<br />
Once the current &#8220;Green Mansions&#8221;  weather pattern (as I sometimes<br />
think of such a spell, recalling my readings of William Henry Hudson&#8217;s<br />
book of that title in my adolescence) exits, my wood-turtle search<br />
strategy will rely heavily on looking into such niches shortly after<br />
the sun has reached them, following a frosty night, or chill, dark<br />
rainy spell. I will continue with some recent-past wood turtle<br />
observations soon-ish.</p>
<p>I have been contacted by a group of four students from Tufts<br />
University (my alma mater, along with the Boston Museum School of Fine<br />
Arts) who want to produce a documentary on wetland preservation &#8211;<br />
development issues and want me to be the main voice. Their intent is<br />
to enter their production in an environmental film festival to be held<br />
at Tufts, I think in the spring. I agreed to do this. They came a week<br />
ago today to do a preliminary filming of me walking and talking<br />
(mostly talking) in a couple of my historic wetland habitats. They<br />
will return in a week for additional filming. I will write more about<br />
this project next time. bis dann, David</p>

			<content:encoded><![CDATA[<p>To begin, I want to clarify something from that previous journal<br />
entry. In describing my going into the spotted turtle habitat I call<br />
the Far End of the Great Alder Carr after tropical storm Irene had<br />
effected a significant recharge<br />
I mention the typical flood periods there as having a &#8220;&#8230; low, steady<br />
drift (of water)&#8221;. This should read &#8220;&#8230;slow, steady drift&#8230;&#8221;. I<br />
regret the typos that invariably show up in my journal entries (where<br />
is my Peg Anderson, my copy editor at Houghton Mifflin Harcourt when I<br />
need her?). It occurs to me that I describe these seasonally flooded<br />
wetlands that are so critical for the spotted turtles, primarily<br />
during hibernation, in some detail in the namesake chapter of my last<br />
book, FOLLOWING THE WATER. And the map shown on the end pages gives a<br />
pretty good picture to go by.</p>
<p>I also wanted to add that as I left the swale after finding that<br />
spotted turtle of 14 July, driving out the logging road, I saw a wood<br />
turtle crossing that dirt road. I have found wood turtles in this area<br />
from time to time over the years, but sightings in this area are very<br />
infrequent. The reach of the permanent stream that flows through this<br />
part of the Digs is for some distance more suited to painted and<br />
snapping, and occasional spotted and Blandings turtles, than wood<br />
turtles. Due to the rather level lay of the land and beaver activity,<br />
it is more a marshy stream, with sediments predominant; rather than<br />
the scoured, sandy, gravelly bottom of a moderate gradient favored by<br />
wood turtles. (I often refer to the overlap in stream and river<br />
habitat of wood turtles with that of wild brook trout.) This was a new-<br />
to-me 14 year old female who had recently been attacked. Her front<br />
legs had wounds at the joints (fortunately the predator was not able<br />
to work her legs out of her shell and eat them); and her tail was<br />
badly chewed right to the cloacal opening. These will heal. It is<br />
possible that a dog had discovered her, as there is a house nearby,<br />
one built on what was formerly a turtle-nesting site (&#8221;Snapping Turtle<br />
Knoll&#8221; in Year OF THE TURTLE). Or it may have been a natural predator.</p>
<p>On 2 August I found a far less fortunate wood turtle in the main area<br />
in which I have observed them. A long-familiar female, one of the<br />
oldest of her colony I suspect, had been hit by mowing equipment<br />
during the last haying. I could piece the four sections of her<br />
carapace together for identification; the fragments of her plastron<br />
were &#8220;exceedingly smooth-worn&#8221;, as I have described her in past<br />
notebooks. She was one of a dozen or so females who seem to do all the<br />
egg-laying, one of those wood, spotted, or Blanding&#8217;s turtles turtles<br />
l think of as a matriarch of the population. She has been nesting over<br />
the 24 seasons I have been making observations here; doubtless she had<br />
nested for some years before i first recorded her, and doubtless she<br />
would have continued for some decades more were it not for this<br />
casualty. She was right at the border of the mown field and the narrow<br />
strip, ranging from 1 &#8211; 3 meters in width generally, between the field<br />
and the tree line of the wooded ridge above the brook. The wood<br />
turtles here are in the main well-distanced from a paved road, but<br />
different kinds of road kill can happen, and every such fatality,<br />
particularly of a breeding-status female, is a great loss to the colony.</p>
<p>I continued wood turtle searches along these edge habitats, or<br />
ecotones in following weeks, finding a number of them. On the 23rd of<br />
August I took up my annual walking of the dusty trails of the<br />
hatchling wood turtles. Perhaps &#8220;sandy trails&#8221; would be accurate, but<br />
it is typically a dry and rather dusty time of year (I describe this<br />
in detail in &#8220;A Drink Along the Way&#8221; in FOLLOWING THE WATER). This is<br />
one of the most compelling times of my seasonal rounds with the<br />
turtles. I set out a bit later than usual &#8211; wood turtles generally<br />
hatch earlier than the other species in this region, beginning around<br />
mid-August (earlier, on occasion) and often ending before the first of<br />
September. One factor in my irresolution this season was that nest<br />
predation was extremely heavy at nesting time. During that period I<br />
sadly documented 13 nests that had been taken by predators, and it<br />
seemed quite possible, if not likely, that one had been spared. This<br />
made the odds quite prohibitive that I would have even one of those<br />
encounters along the trail with a nest-to-water journeying hatchling.<br />
But again, this is for me a most compelling moment in the season of<br />
the turtles, one that draws me back in spite of all odds, reluctances<br />
and discouragements of various kinds, etc. And extremely slender odds<br />
of finding are a constant of so many turtle searchings &#8211; searchings in<br />
general. I saw what looked like the possible exit hole of a nest from<br />
which hatchlings had successfully emerged. But it wasn&#8217;t as clear as<br />
is usually the case, and I saw fine extracted sand around the vague<br />
rim of the depression in the sand. If turtles dig out, all sand or<br />
earth falls back in behind them &#8211; they dig out, all others, from<br />
exploring predators to wasps burying the prey with which they deposit<br />
their eggs, dig in, scattering very small to sizable mounds of sand<br />
beyond the excavation. I walked on.</p>
<p>The next day I looked at the small depression again. I looked more<br />
closely. The fine sand around the rim had actually been removed by<br />
ants who had had infinitesimally small holes right beside it. I knelt<br />
down, reading the sand far more carefully, clearly &#8211; suddenly I felt<br />
all but positive that this was a somewhat obscured exit hole. I dug<br />
in, quickly encountering five wood turtle eggs that had failed to<br />
develop, and then felt a hatchling who was still in the chamber. The<br />
hatchling was alive. Beneath him I found the shells of five eggs that<br />
had been pipped. One belonged to one not yet ready, for whatever<br />
reason, to leave the nest. Four siblings had broken free of their<br />
eggshells, dug out, and taken up their nest-to-water journeys.</p>
<p>I brushed sand away from the little turtle I had been so lucky to<br />
find&#8230; odds, luck&#8230; and of course the reality that one never knows,<br />
one must simply go and look. And look again&#8230; and again. Once again,<br />
this comes to me so often, I spoke that quote of Louis Pasteur&#8217;s, &#8220;In<br />
the field of observation, chance favors only the prepared mind.&#8221; My<br />
mind should have been far better prepared the day before; luck gave me<br />
another chance. I had reason to believe that this might be my<br />
hatchling wood turtle for the year. But two day later as I stopped my<br />
car along the hayfield road, where there is some sparse grass in the<br />
shallow ruts, and parts of the sand road are in the shadow of a tall<br />
stand of white pines, as I have over the years found hatchlings<br />
wandering right along that road at mid-day, and they would be very<br />
hard to see here. So I get out and look ahead before proceeding, and<br />
then backing in to where I leave my swamp car in the great shadow.<br />
Just a few steps ahead I met one. This has happened often enough over<br />
my history here that I am led to believe that hatchling wood turtles<br />
on nest-to-water journeys at mid-day, when it can be as hot as any<br />
desert out on the sunlit sand, orient toward the shade cast by the<br />
white pines that stand on a ridge above the brook they are seeking.</p>
<p>I will have to leave my account of Jefferson salamanders until my next<br />
posting. Hasta entonces.</p>

			<content:encoded><![CDATA[<p>My last spotted turtle sighting and capture occurred on the 14th of<br />
July. I waded into the Swale, which still had water depths in some<br />
compartments that would seem to support spotted turtles&#8217; lingering<br />
here a while yet. Last year this vernal pool habitat, the epicenter of<br />
my spotted turtle encounters for over thirty years (and a central<br />
setting for four of my books), was completely dried up by late May.<br />
The vagaries of the seasons; the shiftings of the spotted turtles &#8211;<br />
always a fascinating dynamic, and one that, outside of radio tracking,<br />
allows few findings of these turtles, and hence few insights into its<br />
progress. I searched from the southern edge of this seasonal wetland<br />
to its northern extremity, which I refer to as the &#8220;Far End&#8221; in my<br />
Digs notebooks. And I had no sightings until I reached that far end.<br />
It holds the largest and deepest pool in the Swale&#8217;s wetland basin.<br />
The sighting and capture of a long-familiar male was a classic one for<br />
me, something familiar to me since those first days as an eight year<br />
old discovering spotted turtles and their world. First there was a<br />
slight jostling of emergent sedge, the inflated sedge that has come to<br />
proliferate in the deeper depressions of the Swale. The brief, reedy<br />
movement, set in various stirrings caused by the wind and occasional<br />
frog activity, signaled a turtle on the move. Within seconds there was<br />
a sharp alarm cry from a young green frog who made a swift departure<br />
from that section of sedge. The suspected spotted turtle was not in<br />
pursuit of the frog; but some presence in the water triggered his<br />
flight.<br />
Then &#8211; and this is how it commonly goes &#8211; long minutes of no further<br />
evidence of a turtle, as I kept still and waited. And waited. At<br />
length the head of a male spotted turtle appeared above  water. As is<br />
all but invariably the case, this initiated another long period of<br />
waiting-out the turtle I would now love to take in hand to identify.<br />
Thusly I have spent countless swampwalking hours over the course of<br />
six decades and counting. The turtle finally ducked his head under and<br />
I made my move. He detected this and at once made his own move.<br />
Happily I was able to track his progress enough, despite losing sight<br />
of his movements for a second or two here and there (this part of the<br />
process takes place with contrasting quickness), to grasp him and<br />
bring him to the surface. This turtle has chipped marginals at the<br />
right rear edge of his carapace, a distinctive mechanical injury I<br />
have backed up with a single slight notch, features that allowed me to<br />
know him as one with whom I have a long history. And an uncommon one,<br />
in that I first recorded him as a very young turtle.</p>
<p>Following that my turtle time centered on wood turtles, until the wild<br />
recharge of the Swale and other seasonal wetland haunts of the spotted<br />
turtles by the tropical storm that hurricane Irene had become upon<br />
reaching this area. Such rain events have on occasion in the past<br />
spurred a return of at least some spotted turtles to the Swale, and<br />
initiated a period of activity in the shrub swamps to which they<br />
return at summer&#8217;s ending for their overwintering. The Swale was<br />
filled to the brim and over the brim &#8211; always wonderful to see &#8211; but I<br />
found no sign of spotted turtles there. I went on to the Great Swale,<br />
wondering if I might see one there. This is a central setting for YEAR<br />
OF THE TURTLE, and another former epicenter for the spotted turtles.<br />
But, to put it briefly, turtle sightings there have declined as plant<br />
succession has advanced over the past two decades, to the point that I<br />
rarely make searches here, even at the time of emergence from<br />
hibernation. Another significant factor in my not coming here but a<br />
couple of times a year is that the near-impenetrable tangles<br />
vegetation have become flat-out impenetrable. As described in TURTLE<br />
and other writings, moving through this wetland is an all-body<br />
experience. This was arduous even ten years ago, before the<br />
encroaching sedges, alders, red maple saplings, et. al. had taken over<br />
all but completely &#8211; and I was that much younger. The channels and<br />
pockets and pools in which I found so many spotted turtles in those<br />
earlier years are essentially untraceable now; I believe they are<br />
overwhelmingly unnavigable even for the turtles. There is virtually<br />
nowhere that I can look into the water (this is still a seasonal flood<br />
compartment, one of those natural flood control acreages that have<br />
been lost to human alteration of the wetlandscape); nowhere I might<br />
possibly see the head of a turtle above the surface. Nor could I<br />
detect turtle movements here, were there turtles present. I struggled<br />
mightily, making little but exhausting progress, remembering former<br />
times here. I had to turn back, thinking it might still be possible to<br />
search and find here at thaw, when at least the new growth had not yet<br />
begun. But so much is now woody tangles and persistent masses of<br />
herbaceous sedges and ferns, that I have great doubts about any future<br />
expeditions here.</p>
<p>On to the Far End of the Great Alder Carr, the downflow end of this<br />
large Great Swale-Great Alder Carr wetland depression in the<br />
landscape. It is here that I have come to find spotted turtles at<br />
emergence from overwintering in recent years. It is difficult enough,<br />
though not as challenging to make my way through as the Great Swale<br />
was even when I first discovered it. There are wadeable/navigable<br />
channels and pools; it is possible to sight and capture spotted<br />
turtles here. And, of great import, there are turtles here. but the<br />
water was deep, by spotted turtle habitat parameters, that is to say<br />
close to waist deep; and the season&#8217;s rampant growth, primarily of<br />
royal fern on shrub mounds, made even places I could wade through<br />
close to unsearchable. I doubted that with the water depth, and<br />
stronger sweep of floodwater through the compartment, which usually<br />
has a very low, steady drift until even that falls away at the time of<br />
low water, would favor activity by the turtles i sought. as is my<br />
custom, my postings on this journal site are too far apart and get<br />
into rather long accounts. I will stop here for now and try to cover<br />
what is sketched out in my heading before long. To be continued&#8230;</p>

			<content:encoded><![CDATA[<p>Never quick on the update, I have been slower than usual here as my<br />
observations on this year&#8217;s nesting by wood, spotted, and Blanding&#8217;s<br />
turtles have been marked by very heavy nest predation, a subject I<br />
have not been eager to write about. One goal I had for this season was<br />
to try to identify who the nesting wood turtles are, after not having<br />
made any systematic censuses in some years. I attempted to time my<br />
searches to find turtles positioning themselves to nest, or out in the<br />
open during the very beginning of their nest-searching. It is not<br />
uncommon for them to explore for two or three days even, and certainly<br />
to have a period of trial scrapings and diggings before committing to<br />
a site. (Would that this were a more effective deterrent to<br />
predation.) I have observed this with spotted and snapping turtles as<br />
well. Frequently enough they even abandon completed chambers. There<br />
are instances of females setting right to work, digging a nest, laying<br />
eggs and covering them all in one relatively brief act (except for<br />
spotted turtles perhaps, as even if they begin at the site they will<br />
commit to they may nest through the night and complete as late as 9 or<br />
10 the following morning). I had some success in this, reading weather<br />
patterns correctly and calculating nesting times, with finding four<br />
out to nest on a late afternoon associated with a rain event following<br />
a hot and dry period. I also found morning nesters; and was lucky<br />
enough to come upon several who had just left completed nests. I did<br />
come upon a couple of turtles in process, who abandoned their sites<br />
(no eggs) &#8211; they may or may not have done this had I not appeared. One<br />
subsequently moved a slight distance and nested all the way through. I<br />
have yet to tally, but believe I identified five or six out of eight I<br />
know to have nested (via trial digs in certain sites, and nests i was<br />
quite certain had been completed). One significant result was finding<br />
only one nesting turtle associated with the west brook of this two-<br />
stream confluence area. She is the one intact adult female I have<br />
found in each season following the winter of great otter predation<br />
five or six years ago. The east branch was hit far harder than the<br />
west, although there were otters present in both. I had expected a<br />
setback in nesting numbers in the vicinity of the east brook, and have<br />
not found signs of nesting associated with this west brook since the<br />
otter attacks; although I did find one yearling (in fall, finished<br />
first growing season). It is possible that this turtle came from the<br />
west brook nesting area; Sheila Tuttle and I documented this in the<br />
1993 study she conducted as  her Masters thesis for Antioch New<br />
England. But it is far more likely that the little one came from a<br />
nest I was not able to find.</p>
<p>Not wishing to cause any further disturbance this nesting season, I<br />
did not make searches for turtles during the latter part of the<br />
activity. I was not able to locate the nest site of the east brook<br />
turtle; what I had felt all but certain was a completed nest proved to<br />
be a decoy. I have on occasions found nests dug and covered but<br />
containing no eggs. I made a day search of all known nesting areas<br />
when I felt nesting had just been completed and found that seven of<br />
the eight known nests had been dug up by predators &#8211; so early in the<br />
going. Not unusual, the percentage of nests taken, or the immediacy of<br />
the predation. Last season I did not search the nesting areas &#8211; as is<br />
the apparent norm for wood turtles, the same sites are used year after<br />
year &#8211; until it was time for the emergence of hatchlings. A few days<br />
into this quest I began to find nests dug up by predators, until in<br />
all seven out of eight nests I was able to locate had been taken.<br />
Unfortunately these contained hatchlings on the verge of pipping and<br />
leaving the nest, or even out of their eggshells and ready to dig out.<br />
The one successful nest launched seven hatchlings out of seven eggs.<br />
The scenario of that season, and what is portended for this, is of low<br />
to zero hatchling survival. This made, and will make again this year,<br />
my mid-August into September wanderings during which I look to<br />
encounter hatchlings on their nest-to water journeys (one of the key<br />
times in my year of the turtle, as described in &#8220;Nest to Water<br />
Journey&#8221; in SWAMPWALKER&#8217;S JOURNAL and &#8220;A Drink Along the way&#8221; in<br />
FOLLOWING THE WATER&#8230;), an all but certain futile exercise-cum-<br />
ritual. There was one exceptional year in which I had not documented<br />
nesting at all, but dedicated days to repeated roamings of the nesting<br />
areas and surrounding terrain that I know hatchlings to traverse, day<br />
after day, and in the end had found 11 exit holes of successful nests<br />
and encountered 49 free-range hatchlings. I even came upon five nests<br />
that were in the process of hatching out. I did not find a single nest<br />
that had been dug up. The many hours of crisscrossing this habitat<br />
were surely richly rewarded. There have been years of extremely<br />
limited predation, and years like the past two. I can only hope that<br />
whatever dynamic is at work (I cannot presume to offer a theory)<br />
continues to be cyclical. An annual trend of the degree of nest loss<br />
indicated by this season and last would certainly downgrade the<br />
remarkable recruitment of young into the colony that has been the<br />
standard over my observations here since 1986. I am as puzzled by the<br />
predators as by the coevolutionary forces that may be at play in this<br />
of turtle nesting. Although the wood turtles nest in bare soft sand, I<br />
rarely see footprints I can positively identify. What I do make out<br />
suggests skunks.</p>
<p>I made only two dawn searches for spotted turtles who might have<br />
nested through the night (I describe this, in some past years of data-<br />
gathering a much more dedicated proposition, in &#8220;Ariadne Nesting&#8221;, in<br />
SELF PORTRAIT WTH TURTLES).  I found none in the process. What I did<br />
find my first time out was a freshly depredated Blanding&#8217;s turtle<br />
nest, in an area favored by spotted turtles, but used at times by<br />
painted turtles and one or two snapping turtles as well. And this was<br />
in a place far removed from any in which I had ever found any sign of<br />
nesting by Blanding&#8217;s turtles. Fourteen eggs were eaten; the clutch<br />
size and the shape and color of the eggshells positively identified<br />
the species of the nester. It was not easy to look at this sunrise<br />
scene. This species is evidently present in very low numbers in the<br />
greater ecology, broader landscape, included in what I call &#8220;the Digs&#8221;<br />
and well beyond. I thought again of the coevolutionary forces and time<br />
involved in this matter of Blanding&#8217;s turtles being here. The turtle<br />
who made this ill-fated nest had likely taken twenty years to reach<br />
breeding age. Then she began to make her long nesting sojourns, dug<br />
her nest and committed her eggs. I thought of the one year of this<br />
nest, that is the time from last nesting season through the activity<br />
of summer and autumn, the long hibernation and finally the emergence<br />
for another round of the seasons, courtship and mating, and then the<br />
process of nesting and the journey back to her resident wetland. All<br />
of this undone in a matter of minutes, quite likely the night of her<br />
nesting. As I counted the eggshells I thought of the entire year that<br />
must pass, and all that is incumbent on this matriarch of her kind,<br />
before she has another chance to entrust a clutch of eggs to a nest.<br />
Her  nesting history here may cover six decades or more, and out of<br />
those how many hatchlings might be generated&#8230;  and out of those, how<br />
many might live the twenty years to begin to take a place among the<br />
breeding adults of the population? These thoughts deepened as on my<br />
second daybreak search I found what looked like another Blanding&#8217;s<br />
turtle nest that had been dug up. The site was a likely one, the<br />
eggshells looked right for the species, but the clutch size of five<br />
eggs caused some doubt, and I wondered if it could have been a painted<br />
turtle&#8217;s nest. However, clutch size ranges from 3 to 22 in this<br />
species, and this could have been the work of a first-time nester.<br />
Several days later I went to a site in which a Blanding&#8217;s turtle has<br />
nested over the years. I had been hoping to find a completed nest,<br />
checking every day to see if there any signs to indicate nesting. I<br />
had thoughts of relocating a nest if I found one, to hatch out in my<br />
back field. I rarely and reluctantly do this &#8211; no doubt all the dug-up<br />
nests I was seeing was influencing me. On my mid-day look-in, I found<br />
a nest that had been taken: 16 eggs.</p>
<p>There is a Blanding&#8217;s turtle presence here. All indications are that<br />
it is limited, but there is a presence. My belief that this will<br />
persist as long as the habitat remains intact and extensive was shaken<br />
by these observations. But I am seeing only who knows what fraction of<br />
the presence and signs of its persistence. And my time, for all the<br />
artist-naturalist&#8217;s wandering and specific field documentation I have<br />
spent, dedicated, here, is of course a snapshot in the time of this<br />
species in this ecosystem, whose persistence itself &#8211; as with<br />
ecosystems globally &#8211; is by no means assured.</p>
<p>I found several dug-up nests in sites in which spotted turtles have<br />
nested historically; the clutch sizes of three and four, size and<br />
shape of the eggshells, suggested they were of this species. Among<br />
eggshells at one site I found an intact egg. This happens sometimes,<br />
though rarely. That one egg I have transferred to my back field and<br />
screened against predators.</p>
<p>                                                                                                                                                                           * * * * * *</p>
<p>Two weeks or so ago I had a most interesting interview, by swamp and<br />
in our gallery, with Mary Helen Miller, a writer for the Christian<br />
Science Monitor, who is writing a piece on me for the newspaper&#8217;s<br />
weekly magazine. This for a column entitled &#8220;People Who Make<br />
Difference&#8221;. As I told her, I wish I could make the difference I would<br />
like to make, that of getting people to move beyond stewardship and<br />
even conservation to preservation.<br />
This is something I address in all of my talks, and in my books. Be<br />
that as it may, I am greatly pleased, and honored, to be a subject of<br />
this theme. Our extended talk was a pleasure for me &#8211; I am fortunate<br />
to have such an insightful and skilled interviewer/writer take me on<br />
as a subject. This week I had another fine session, this with<br />
photojournalist Ann Hermes, who came to take an &#8220;environmental<br />
portrait&#8221; of me for the article, this by the key spotted turtle vernal<br />
pool habitat that has been a center of my years of the turtle in the<br />
Digs. Ann asked if I might have a turtle for the portrait, and as<br />
spotted turtles are infinitely more photogenic than I, I was happy to<br />
try to have one in hand for the occasion. The afternoon before our<br />
appointment I went into this wetland, which, owing to the abundant<br />
rains around a couple of hot and dry spells this spring into summer,<br />
is nearly at the full flood level of thaw. Last year, spring and<br />
summer were marked by drought, and this seasonal wetland was dried up<br />
by the end of May. The spotted turtles were of course long gone. But I<br />
knew there would be at least some here yet, and so made a wading<br />
search. The degree-of-difficulty of seeing one, much less getting one<br />
in hand &#8211; as often described in my writings &#8211; was very high. Water<br />
depths of eighteen inches generally, and rampant emergent and<br />
submersed vegetation made it very much &#8220;advantage turtle&#8221;. I had one<br />
sighting of a male with his head up, and then another of turtle<br />
movements briefly in emergent reed canarygrass; but these were turtles<br />
quick to vanish before I could get near them. But then, once again,<br />
the turtle gods were very good to me. I saw unmistakable jostlings in<br />
a dense emergent patch of meadowsweet: the movements (slight, brief)<br />
of a turtle, and very likely a spotted turtle. I approached, waited,<br />
saw another slight movement, could not really get a bearing on a<br />
precise location, but knew I had to make a stab at catching the turtle<br />
who was in there somewhere. I lunged with both hands. They sank over a<br />
foot in the shrubby submarine tangles and in the near-undecipherable<br />
melange I felt my left hand come down on a turtle shell. I pinned the<br />
turtle, struggled myself into a position in which I could manage to<br />
get myself upright, still gripping the unlucky turtle. But I was very<br />
lucky indeed, for I held not only a spotted turtle, but one I had<br />
never seen before, a 9 or 10 year old who appeared to be a male just<br />
beginning to take on the secondary sexual characteristics of his kind:<br />
darkening (somewhat) face, slightly indented plastron, and cloacal<br />
opening just beyond the outer edge of his carapace. He was a brilliant<br />
specimen, head and shell richly adorned with large and very bright<br />
yellow spots, and more spots on his legs and tail than I have ever<br />
seen on a spotted turtle of any age&#8230; legs and tail sharply reminded<br />
me of a spotted salamander.</p>
<p>I went on to make two more captures, one of a five or so year old<br />
snapping turtle and then an adult female spotted turtle. She was<br />
marked number 10; goes back a long way in my notebooks, perhaps 25<br />
years. When did I last see her?</p>
<p>This has turned into quite an epistle. Of Star Island, I will say for<br />
now that my appearance there as visiting faculty for Southern<br />
University of NH, at a writer&#8217;s conference, was absolutely terrific in<br />
every way. I am indebted to Diane Les Becquets, Head of the Master&#8217;s<br />
Writing Program, Rick Carey, Merle Drown, other faculty and some 43<br />
grad students for a deeply rewarding and inspiring occasion, about<br />
which I will write next time.</p>

			<content:encoded><![CDATA[<p>With customary regrets over how weeks elude me (in all my endeavors) I<br />
try to summarize some turtle observations and update this journal<br />
site. On the 12th of May (the day after my last journal entry, I<br />
believe) I had another signal turtle encounter when I found a familiar<br />
eight year old Blanding&#8217;s turtle in the migration stream used by a<br />
number of spotted turtles to get to the Swale. Any Blanding&#8217;s turtle<br />
find is a cause for celebration, as they are few and far between in<br />
the large wetland complex that is the epicenter of my spotted turtle<br />
observations. Adults, except for females seeking nesting places, are<br />
virtually absent, keeping to deeper waters beyond this area, but<br />
ecology connected with it. I find young ones, up to age fifteen (but<br />
mostly younger, smaller individuals), on rare occasions, as their<br />
seasonal movement patterns closely follow those of the adult spotted<br />
turtles. Given the chance nature of Blanding&#8217;s turtle finds, I have a<br />
most unusual history with this eight year, who I first found as a one<br />
or two year old (refrain: it is in my notes; need to re-visit past<br />
notebooks some lifetime) and who I have found almost every year since.<br />
This is indeed a fortuitous consequence of this turtle&#8217;s intimate<br />
connection with the movements of the spotted turtles who overwinter in<br />
the Great Swale and great Alder Carr and travel to the Swale vernal<br />
pool habitat every year; remaining there until water levels fall too<br />
low to provide escape cover, usually from the end of June into July,<br />
later in very rainy summers. A key result of this history is that I<br />
have measurements of a wild, free-living juvenile-subadult Blanding&#8217;s<br />
turtle over this time frame. [I have an abundance of such records with<br />
young age class wood turtles, who - in great contrast - I have<br />
encountered with high frequency  over the years.] A compilation of<br />
times and places for such individuals is another key value of my field<br />
notes. And of course I always wish there were more notes with more<br />
details, etc. I would say that this young Blanding&#8217;s turtle has<br />
something on the order of twelve years to go before reaching breeding<br />
status. It is ever cause for reflection when I see a spotted, wood, or<br />
Blanding&#8217;s turtle that has survived eight, ten, twelve, or more years<br />
but still has years to go before becoming a breeding member of his or<br />
her colony.</p>
<p>On the 29th of April, two days after the encounter with &#8220;Bright<br />
Yellow&#8221; that I detailed in my last post, I observed a pair of spotted<br />
turtles engaged in the courtship chase I describe in YEAR OF THE<br />
TURTLE. (A print of the watercolor I produced to illustrate this<br />
elaborate ceremony &#8211; and other turtle art prints &#8211; is available via www.carrollstudiogallery.com<br />
; see also my artist&#8217;s page at www.Lake-Sunapee-Living.com; and coming<br />
soon: www.davidcarrollturtleart.com) But of course the season moves<br />
along too quickly to truly follow &#8211; there is joy and anguish in trying<br />
to keep up with it all, even if there were nothing else in life to do<br />
- and now it is nesting time.<br />
On the 28th of May, after several heated days following the extended<br />
rainy season of some three weeks of cool, even chill, dark and rainy<br />
days (vital to maintaining the water level in the Swale, overcoming<br />
for a time the effects of a culvert&#8217;s draining) I observed an adult<br />
female out in the late afternoon, along the margins of the greatly<br />
reduced nesting terrain associated with the east Brook. She could have<br />
begun her searching for a nesting site. This can take days, or on some<br />
occasions be the work of a single evening or morning. Soon after, I<br />
found one definitely engaged in a search for a place to nest. She had<br />
already dug a trial nest and abandoned it (common practice with this<br />
species) and her carapace was well-covered with sand along the<br />
margins.  As I am making a concerted effort this year to take a census<br />
of the wood turtles in the confluent two-stream central habitat for<br />
the colony I have followed for some twenty four years I picked her up<br />
in order to make an identification. I hated to do this, but a major<br />
quest for me is to see who the nesters are at this time, with a view<br />
to the great otter depredation of adults of four or five years ago.<br />
And the turtles will in time go about their necessary business. In<br />
fact this one, a long-familiar older female, did go on to complete her<br />
nest that same evening despite my intrusion &#8211; I found it the next<br />
morning. And that same morning, as I drove in on a dirt road at the<br />
East brook area, I saw a wood turtle nesting in a sandy, scraped-out<br />
niche used at times by farm equipment. This was precisely where I saw<br />
my first wood turtle nesting, 24 years ago. Generally the passing of a<br />
car does not disturb a nesting turtle enough for her to abandon her<br />
project. As she was well-dug-in I did not want to go near her, and was<br />
going to continue with my survey. But as I looked back, I saw her<br />
crossing the narrow dirt road, heading back to cover along the brook.<br />
So, I was able to capture her for identification. She was one of<br />
twelve wood turtles we outfitted with radio transmitters for a study<br />
Sheila Tuttle conducted a her Master&#8217;s Thesis for Antioch New England<br />
in 1993. She was one of two subadults I chose to include, along with<br />
the ten adults, in this radio-tracking study. As I recall, she was 11<br />
years old then, which would put her in her 30th year.</p>
<p>On the first of June, following a very hot and humid spell of several<br />
days in the upper 80s and even reaching 90 degrees, a day when tornado<br />
warnings were posted for NH and adjacent areas, a thunderstorm passed<br />
by to the immediate south of the wood turtle center, and a brief<br />
period of rain fell. This lasted less than ten minutes &#8211; maybe five,<br />
as I think of it &#8211; not at all the rain I had hoped for, and gardens<br />
and swamps have been affected by another dry spell. At least we were<br />
spared the severe storms that struck elsewhere; such as the tornado<br />
that struck Monson, MA, site (along with Wales) of the Norcross<br />
Wildlife Foundation&#8217;s sanctuary, Tupper Hill, where I served as artist-<br />
Naturalist form 1994-1997 (as described in my SELF-PORTRAIT WITH<br />
TURTLES). But this pattern of well-heated days following a cool, dark,<br />
dry spell, followed by late afternoon rain and imminent or actual<br />
thunderstorms is a classic signal for wood-turtle nesting. It occurs<br />
with other species as well, but seems to me to be a hallmark of the<br />
wood turtles. Between 4:30 and 6:30 I found four out to nest. As with<br />
the previous two observed, these were older (30 years and up,<br />
impossible to determine as they were already beyond accurately aging<br />
when I first found them, twenty and more years ago) long-familiar<br />
turtles. After this day of storms and near-storms, the weather went<br />
from Guatemalan to Nova Scotian, from blazing sun, high heat and<br />
humidity to heavily clouded days with strong winds (15-25 mph, gusts<br />
to 35), cool to chill, and very low humidity; a pattern  not typically<br />
conducive to nesting. I intend to continue my quest to identify<br />
nesting females. So far, the general (prevailing?) tendency appears to<br />
be of the nesting in the colony to be carried out by the older<br />
females; individuals I think of as the matriarchs. But I want to see<br />
if any in the 15-20 year class nest as well, and hope I can be in all<br />
the places at all the right times to get a handle on the age<br />
distribution of those who nest.</p>
<p>My census continues, and will through the  season, something of a<br />
roundup to see who is still here, who is not, and new recruits into<br />
the colony. Initial findings strongly bear out that recruitment here,<br />
demonstrated by finding turtles in the 1-15 year age class, is<br />
unusually high, based on what I have read in the literature about<br />
other study areas, and my conversations with others who are engaged in<br />
long-term studies of wood turtles (I am a bit out of touch with these<br />
sources in recent years, but believe the scenario holds, with findings<br />
of subadult turtles uncommon to rare). Already this year I have found<br />
a number of previously undocumented 3, 6, and 9 years olds. It<br />
continues to amaze me that I find turtles who have lived 2-10 years in<br />
an area of no particular great extent that I have covered so closely<br />
for so many years. I found a 13 year old who is missing both front<br />
legs but still surviving, no doubt one of the many victims of the<br />
winter of heavy predation by otters; but I am not seeing a number of<br />
double-amputees I found the first-third years after their injuries. My<br />
impression is that the wood turtles can survive the loss of feet or<br />
half or entire limbs, but those more severely handicapped may not<br />
survive long-term. Again, I hope more searches and more finds bring me<br />
a clearer picture of these and other dynamics.</p>
<p>A week ago I had a most interesting interview with Mary Helen Miller,<br />
who is writing for the Christian Science Monitor&#8230; a three-hour<br />
dialog in our studio gallery and out by the swamps. She is writing<br />
piece for the paper&#8217;s weekly magazine, for a column entitled &#8220;People<br />
Who Make a Difference&#8221;. I am honored by this of course, but surely<br />
wish I could make much more of a difference in that difficult area of<br />
inspiring our culture and economics move beyond conservation to<br />
preservation, as often addressed in my books and always in my talks.<br />
More on this difference another time. I am not sure when Mary Helen&#8217;s<br />
article will appear.</p>

			<content:encoded><![CDATA[<p>Mid- april into early May is a key time of turtle migration in the<br />
primary areas I have observed over the past thirty years. As described<br />
in YEAR OF THE TURTLE and in SWAMPWALKER&#8217;S JOURNAL (v. &#8220;Migrations&#8221;.<br />
p. 175 ff.) when the first really heated days occur, with temperatures<br />
above 70 or so, and especially in the 80s (if such temperatures occur<br />
in the springtime&#8217;s early going) turtles begin to shift from niches in<br />
which they have overwintered to the habitats of their critical early<br />
foraging and, for adults,  mating. I suspect that these journeys had<br />
already been under way when I sighted my first spotted turtle in the<br />
Swale, a large vernal pool habitat with emergent reed canarygrass; and<br />
tussock, inflated, and other sedges, bordered by dense emergent alder<br />
and winterberry. This spring has had spells of dark and rather chill<br />
weather, with only two days or so of days with full sun and<br />
temperatures in the 70 -80 degree range. But the turtles have taken<br />
advantage of parts of days when these journeys were favored by travels<br />
out and away from their winterholds. On the 27th of April I saw a pair<br />
of spotted turtles, male and female, basking together on a tussock<br />
sedge mound in the Swale. It is not uncommon to find both sexes<br />
basking in close proximity at this early in the season, so close to<br />
their time of courtship and mating. They were out beyond the dense and<br />
difficult shrub border, with its myriad interwoven stems and branches,<br />
and more of their woody growth horizontal (from the water surface to<br />
their crowns) than vertical. I knew I could not approach them without<br />
having them take to cover in the water, so backed away without being<br />
noticed and spent time in a key migration stream, a slender, shallow<br />
slip of water through alder and red-maple swamp, to see if I might<br />
encounter others on their way to the Swale. (This is a primary setting<br />
in my FOLLOWING THE WATER.) I encountered no traveling turtles and<br />
returned to look in on the Swale, where &#8211; almost three hours later &#8211;<br />
the pair of spotted turtles was still basking. Again I knew that I<br />
could not sneak up on them in their clear space, but decided to wade<br />
into the shrub border and on out to the extensive grass and sedge zone<br />
in which they were sunning themselves. I might be fortunate enough to<br />
come upon a turtle in the water who was not aware of me. My struggle<br />
through the shrub margin took awhile, and of course could not help but<br />
be observed by the basking turtles, and they were long gone by the<br />
time I waded into the clear. Clear above the water that is; this great<br />
pool (perhaps two and a half acres in all) is filled with submergent<br />
stems and blades, dense mattings of them, from the previous year&#8217;s<br />
rampant growth. And this thick array of sunken vegetation serves each<br />
spring as escape cover for the spotted turtles in a wetland with a<br />
firm (vs. the usually favored deeply mucky) substrate and only ten to<br />
eighteen inches of water (mostly on the order of foot deep). It is<br />
absolutely remarkable how quickly and completely they can vanish in<br />
this melange, even at fingertip range from the one who would capture<br />
them for identification&#8230; it never ceases to amaze me, despite my<br />
long history with such escape-cum disappearances.</p>
<p>By the time I got the sedge mound on which the pair had been basking I<br />
felt that one or the other might be ready to put his or her head above<br />
water; maybe within my grasp (that means very close, as described<br />
above). So I adopted my wait-and-watch mode, keeping still while<br />
scanning the water round me, and looking into the few openings in the<br />
underwater vegetation. Before long a male did surface, presumably he<br />
who I had interrupted with my awkward movements in wrestling my way<br />
through the shrubs. He was only a stride and a lunge from my right<br />
hand, but I knew it would be all but impossible to make even such a<br />
small move in time to grab him. He went into that &#8220;stare&#8221; &#8211; the only<br />
way I can describe it &#8211; that I have found to be characteristic of<br />
spotted and Blanding&#8217;s turtles. I have gotten great back pains from<br />
keeping absolutely still and trying to wait out one of these turtles<br />
in such a&#8230; vigilant trance? Only rarely have I succeeded in &#8220;out-<br />
staring&#8221; one, having the turtle put his head down into the water and<br />
grant me a second or so (or less) additional time in which to make my<br />
capture-move. This has often been a hazardous lunge among twigs and<br />
branches that at times has gotten me badly poked in the eye, or in the<br />
early going, up to my shoulders and chin in ice water and muck.</p>
<p>I knew I could not endure the waiting-out on this occasion, so made my<br />
futile move. The turtle vanished. My hand in the reedgrass came up<br />
empty. I took a second step forward, and groped among the grasses, but<br />
this, too,<br />
has historically failed to produce a turtle in nearly all cases.<br />
However, my left foot came down upon a turtle, and I felt I had him. I<br />
reached down and pulled forth a spotted turtle, but it was a female,<br />
so not the one I had attempted to capture. Three, perhaps four times<br />
before over all of these years, I have found a spotted turtle with my<br />
foot. As a boy in connecticut, in smaller pools and marshes with<br />
abundant spotted turtles, I actually searched for them with my bare<br />
feet &#8211; that strategy does not apply to these more northern wetlands of<br />
my later years, not even in the exceptionally spotted-turtle-rich<br />
Swale. I immediately recognized the turtle as &#8220;Bright Yellow&#8221;, one of<br />
a handful of turtles to whom I have given a name; one I first found in<br />
this remarkable vernal pool when she was five years old. I thought of<br />
her as a precocious turtle, being large for her age, and of an age<br />
some five years younger than most subadults I have found to migrate<br />
here. And these have been few; it is very rare for me to find a<br />
subadult in the Swale (&#8221;Reedgrass Pool&#8221; in SWAMPWALKER&#8217;S JOURNAL). She<br />
is a particularly brilliantly marked turtle, with abundant bright<br />
yellow spots and glowing orange head, neck, and leg markings. And she<br />
is just as &#8220;Bright Yellow&#8221; as when I first saw her. At the time of<br />
that first encounter I had read about a marvel of a very young Chinese<br />
ballet dancer, whose name meant &#8220;Bright Yellow&#8221;; and I decided this<br />
was too good a fit not to bestow a name. I have seen her in a number<br />
seasons since that first finding, but not in the past three or four<br />
years. As I recall, she was twenty one years old when I last saw her.</p>
<p>As I took great pleasure in being able to see her again and recorded<br />
her in my notebook, I caught sight of a bit of a spotted turtle<br />
carapace moving through sunken reedgrass, made a second lunge and<br />
grasp, and this time came up with a male, in all probability he who<br />
had escaped me. Another long-familiar turtle, first seen as an adult,<br />
and so considerably  older than the one I held in my hand. (There is<br />
no way of ascertaining the age of a spotted turtle after eighteen<br />
years or so.) Here was the &#8220;luck of Guido&#8221;, as I call it, manifest.<br />
Two turtles sighted, that I did not think I would be able to take in<br />
hand and identify, captured not by any great prowess, but by great<br />
good fortune (for the capturer anyway, not those captured). But they<br />
were immediately back in their realm. I think so often of the luck I<br />
have had in my following the turtles through so many decades. Again on<br />
this occasion I had to think I simply did not deserve to have such<br />
pure luck one more time. But another time I was deeply grateful for it.</p>
<p>On the 28th of April I found four spotted turtles in the migrating<br />
stream. And later in the afternoon, around five o&#8217;clock, a large<br />
snapping turtle was near the end of his migration to the great beaver-<br />
supported wetland distant from the Swale. This was a classic sighting<br />
(I write of five making &#8220;the crossing&#8221; &#8211; luckily in this case not of a<br />
road &#8211; in an hour and a half&#8217;s time in &#8220;Migrations&#8221;, SWAMPWALKER&#8217;S<br />
JOURNAL). Here was a majestic snapping turtle of who knows how many<br />
years, making again this critical overland journey, a necessary<br />
seasonal movement that is fatal to so many turtles of so many species<br />
in a world that has become so fragmented by  roadways, cut into small<br />
unsustainable pieces by them. There is something especially impressive<br />
about these large turtles on these migrations following their<br />
hibernations. Their carapaces are sometimes a clear slate blue,<br />
sometimes covered with a patina of algae. This one, I can say<br />
&#8220;gorgeous&#8221;, had massive carapace tinged with green algae along both<br />
sides, and algal coating etched with lines from his or her brushy<br />
passage; and a clear crest of the shallow dome that looked like<br />
burnished plate&#8230; more moving than gorgeous actually, so shield-and-<br />
warrior-like. Such a turtle is truly a warrior of the seasons, of time<br />
and place.</p>
<p>SNAPPING TURTLES: I will give a slide-illustrated talk at<br />
MainstreetBookends  (Main Street, Warner, NH) on Friday, 27 May, at<br />
7PM. No admission charge.</p>

			<content:encoded><![CDATA[<p>The first salamander rain came on the 11th of April, a week after the<br />
first spotted turtles were up from hibernation to sun themselves in<br />
the Great Alder Carr (v. my previous posting: First Turtle&#8230;). As<br />
noted before (and in my books) spotted turtles select overwintering<br />
sites that are the first niches &#8211; often relatively small &#8211; to open up<br />
in wetlands at thaw, when in typical years larger stillwater wetlands<br />
are yet locked in ice and forested uplands still under 2&#8242;-4&#8242; of snow,<br />
prohibiting amphibian migrations. This spring I have happily agreed to<br />
serve as project director for a young friend&#8217;s senior project at<br />
Proctor Academy. Colin Nevins will be mapping and doing an ecological<br />
survey on hie parents&#8217; 35 acre woodland beginning the 5th of May and<br />
continuing for three weeks. His approach will be modeled after maps I<br />
have drawn for my books (as in the endpapers of FOLLOWING THE WATER),<br />
combining field work; plant and animal inventories; field-naturalist<br />
observations; creative writing; art; and photography. His project<br />
property abuts our own 14 acres that consist mostly of forested upland<br />
laced with to seasonal streams and featuring a large vernal pool<br />
habitat; as well as two sections of field and shrub totaling about<br />
three and a  half acres. So this project will be an extension for me<br />
of the habitats on my own land whcih, after 37 years&#8217; residency, I<br />
have never investigated as thoroughly as I would like, since most of<br />
my time is spent in turtle places not far away.</p>
<p>April has progressed with customary gradualism; I was quite sure that<br />
at last on the 11th conditions were right for the first amphibian<br />
migrations and this proved to be true. Colin and I decided to do some<br />
early exploring, as by the official project date the vernal pool<br />
breeding would have long been concluded &#8211; the mating and egg-<br />
deposition, that is to say. We met at 8PM (my kind of commute: half a<br />
mile or so from my fireplace wood stove) to find wood frogs already<br />
chorusing in some number in a vernal pool in the small pasture sector<br />
of his parents&#8217; land. Colin then found a spotted salamander en route<br />
to a pool, crossing the dirt road he lives on. No frog or salamander<br />
had yet entered a pool in woodland habitat across the dirt road. We re-<br />
visited this one the following night and saw spotted salamanders that<br />
had evidently moved in over the course of the rainy night. Males had<br />
already deposited sperm packets in several places. For some reason<br />
this small pool brought thoughts of fairy shrimp to mind &#8211; something<br />
of a premonition. I have never found them in upland pools in this<br />
area, only in vernal pool habitats in the floodplain of the nearby<br />
Warner River, and quite commonly in floodplain pools along the Lamprey<br />
River in southeastern NH during my field work with turtles there from<br />
1993-2003, in league with the &#8220;wild and scenic river&#8221; designation<br />
studies of that river. But soon after wading into this small pool I<br />
sighted some fairy shrimp, an early highlight of the season for me and<br />
auspicious beginning to Colin&#8217;s project.</p>
<p>A survey by a logger friend the previous autumn, with an eye to some<br />
possible selective timber cutting (the Nevins are dedicated to not<br />
doing anything that might negatively impact the ecology of their land)<br />
revealed, if I recall correctly &#8211; something in the neighborhood of 30<br />
vernal pool basins. The terrain is markedly uneven, with very step<br />
ascents and descents, a veritable boulder yard generously studded with<br />
glacial erratics, quite different from the customary turtle habitats I<br />
keep to and evidently well-suited to salamanders. Colin told me that<br />
this pool never dried out, and that intrigued me. This all the more so<br />
when I noticed a small circular pool, lined with stones, perhaps three<br />
feet in diameter, just a few feet off to one side of the vernal pool.<br />
The precision of the circle and the arrangement of the stones would<br />
certainly seem to be the work not of glaciers, but of human hands. It<br />
is not a flowing spring &#8211; neither it nor the adjacent pool has any<br />
inlet or outlet &#8211; but some hydrologic feature may keep it filled with<br />
water throughout the year, and it seems it may have provided a source<br />
of water for some purpose.</p>
<p>Over the next week I surveyed another much larger and deeper vernal<br />
pool on the eastern end of the property that my grandsons Michael and<br />
Ricky Couture had told me about (their property abuts the Nevins&#8217;<br />
woods on that side). I had intended for several years to visit this<br />
pool but never had found the time (or made the effort) to do so during<br />
the vernal season, when my focus is overwhelmingly with the turtles. I<br />
placed four minnow traps in this pool, in which several spotted<br />
salamander egg masses were already in place, and some wood frogs were<br />
calling. Traps yielded two spotted salamanders the first night. The<br />
second night brought only one salamander, but it was a Jefferson<br />
salamander. I had felt certain that this species was also present,<br />
although I have rarely found it in the area.  And I saw two egg masses<br />
that I am 90% certain were those of blue-spotted salamanders. This<br />
pool bears watching, but breeding activity seemed quite limited, and<br />
appeared to have been concluded for the season. I then went to two<br />
pools downslope, and here I found what I am certain are Jefferson<br />
salamander egg masses. One area of deposition was remarkable: a sunken<br />
branch tangle that had been a center for communal egg-laying, every<br />
facet of the branches lined with linear egg deposits, long clear jelly<br />
accretions (some on the order of a foot and a half long) with eggs<br />
plainly visible within. The aggregation looked something like a coral<br />
reef formation.  Minnow traps deployed over the next two nights<br />
captured no salamanders &#8211; I was too late here. Colin&#8217;s project will be<br />
essentially an independent study, but as I check in from time to time<br />
one thing I will have in mind is attempting to net larval salamanders<br />
in this pool once they have reached an identifiable stage of<br />
development.</p>
<p>On the 14th of April I returned to the beaver-flooded wood turtle<br />
area, and immediately upon descending the yet snow-covered shoulder of<br />
the hayfield slope above the inundated alder zone I sighted one<br />
basking in a sheltered spot that featured some fallen branch and<br />
bramble cover. She was a long-familiar adult, one I have seen only at<br />
intervals spaced widely over the years. She is one of the most<br />
secretive members of this colony, and seems to be one of the oldest:<br />
her plastron is worn ultra-smooth; it was that way the first time I<br />
found her some eighteen (twenty?) years ago. As I suspected, the wood<br />
turtles who formerly made use of the alder thickets during their<br />
terrestrial times are restricted to this slope, a rather narrow band<br />
situated between the the extended hayfield and the beaver impoundment,<br />
running parallel to the stream. My laser temperature recorder read<br />
92.5 degrees on the dry leaf-pack next to the turtle and her carapace<br />
gave a reading of 97.4 &#8211; this on an afternoon with an air temperature<br />
of 58 f and brisk, chill winds. A water temperature of 45.5 was<br />
indicated in the main current of the brook. Further upstream I found a<br />
familiar sixteen year old male, one of few, following the winter of<br />
great otter predation five or six years ago (more? &#8211; its in my notes),<br />
who is perfect to the tip of his tail. A very slight notch on his<br />
twelfth right marginal suggests that he may be one I marked as a<br />
hatchling. He has attained a size that would seem to make him a<br />
breeding member of his colony. He was sequestered in limited cover in<br />
a manner very much like the female previously discovered. These<br />
turtles are clearly stuck &#8220;between the devil and the deep blue sea&#8221; in<br />
terms of terrestrial habitat availability. I carried my search on<br />
upstream to the end of their resident reach of this brook, with no<br />
further sightings. As a result of the canopy of second-growth trees,<br />
mostly red maple and then ascending to beech as the streambank rises<br />
to upland woods, the dense low cover that wood turtles require is<br />
almost entirely absent. The area is now primarily open forest floor<br />
with some zones of cinnamon fern that do not provide the complex<br />
layering and thick mattings of fallen vegetation that wood turtles<br />
need. This is strikingly evident at a deep-bend meander in the brook<br />
at the upper terminus of their home range here, a site much favored<br />
for overwintering in past years (during my observations from 1986 to<br />
approximately 1996). With a complete absence of cover for some extent<br />
beyond this part of the stream now &#8211; none of that bankside cover<br />
essential for first basking after emergence from hibernation and<br />
beyond &#8211; it appears that the turtles no longer come here for their<br />
overwintering. There is no other suitable riparian wood turtle habitat<br />
for perhaps a mile upstream, and that is a limited compartment. There<br />
are better options for them downstream, toward a river floodplain a<br />
mile or so distant. Over the course of the season I will attempt to<br />
see if I can gain insights into any movements they may make in<br />
response to these habitat factors. There is much to think about here.<br />
(So often I feel something akin to a headache as I walk and wade this<br />
wood turtle terrain and try to fathom the ongoing ecological processes<br />
and the turtles&#8217; responses to them.) A suite of factors, human-based<br />
and natural, conspires to alter the habitat over time, and in a<br />
landscape increasingly marginalized and disrupted by an array of human<br />
activities options for migration, re-location, which had been in place<br />
for millennia, species like the wood turtle are driven to local and<br />
broader disappearances. I will discuss this further in later postings<br />
(it is lready a feature of my published writings and unpublished<br />
reports). Regrettably the places of wood, spotted, and Blanding&#8217;s<br />
turtles that I have known over the past three decades have become a<br />
paradigm for this well-known, oft-discussed and lamented, but all but<br />
entirely unaddressed phenomenon.</p>

			<content:encoded><![CDATA[<p>Dateline 7 April, 2011.   Still early in the time of emergence from<br />
hibernation: I made the fairly long walk and wade to a compartment I<br />
call the Cranberry Sedge Meadow, or alternately (or simultaneously)<br />
the Sweetgale/Leatherleaf Meadow. This is a wetland I would like to<br />
describe in more detail in the future; a level expanse that at thaw<br />
and into spring is flooded to a depth ranging from 6&#8243;-10&#8243;, rather<br />
consistently throughout its extent. The substrate is solid, a peaty<br />
turf perhaps, built up by its plant community that consists of wooly-<br />
fruited and other sedges, large cranberry, and colonies of sweet gale<br />
and leatherleaf. In recent years, stands of alder have begun to<br />
encroach on the still-dominant vegetative structure. There are very<br />
occasional mucky sinkholes where I drop into gripping muck up to a<br />
foot deep. I have never seen adult spotted turtles here, something I<br />
attribute to a lack of escape cover, as the dense vegetation is<br />
prohibitive for navigation and the substrate predominately non-<br />
burrowable (at least not quickly, something critical to turtles<br />
needing to disappear from harm&#8217;s reach). I have long thought that this<br />
habitat block was likely to serve as a nursery for hatchling and<br />
juvenile spotted turtles and finally several years ago, en route to<br />
look for adults at emergence at its far south end, did find a two-year-<br />
old basking in leatherleaf stems. The broader area is difficult to<br />
search, and looking for little turtles in it would be a paradigm for<br />
the needle-in-a-haystack saying. But since that discovery, which may<br />
well have been a once in a lifetime event, I have searched may way<br />
along the animal trail I wade to reach the micro-niche in which I have<br />
found adult spotted turtles at emergence. This does not shorten my<br />
time in reaching my ultimate destination. This is an area of perhaps<br />
35 square yards, just in from a broader, deeper channel I call &#8220;The<br />
Slough&#8221;; which itself is the confluence of a small stream that runs<br />
through an extensive red maple swamp with a larger permanent stream.<br />
(Guess I need to draw another map someday.) Some years ago I<br />
discovered this restricted zone to be the site of emergence from<br />
hibernation by spotted turtles, three to five on any given day; but<br />
only for a day or to at the very beginning of their season. I was<br />
certain that there was no active-season, resident habitat for them in<br />
the vicinity, and eventually found them to migrate perhaps a quarter<br />
of a mile (not a great distance for them to travel) to a backwater fen<br />
of a large glacial pond for their seasonal feeding and mating. On one<br />
day I made some personal history, stealing upon this site, very<br />
difficult to approach without being seen as the vegetation is almost<br />
entirely below waist-high to me, and in one rush managing to take in<br />
hand all five turtles I had seen basking. To this day I am not sure<br />
how I managed that juggling act. Again, this is a quite-compressed<br />
area that they use. In recent years I have found few or none; and on<br />
this day I saw none. I waited an hour or so, on the remote chance that<br />
I would be there to witness one come up to sun himself.  This did not<br />
occur. I returned again the next day, another featuring ideal<br />
conditions for basking; again I found no sign of a turtle (it is only<br />
spotted turtles who hibernate here; it is typical of this species, at<br />
least in my experience, to overwinter in situations unique to them). I<br />
go through all of my old thoughts (to be discussed at another time<br />
perhaps). as I try to figure out their seasonal connection here.</p>
<p>After this second sojourn here (my last of the year, most likely: they<br />
do not stay here), I returned to the Far End of the Great Alder Carr,<br />
where I had a recapture of that first turtle of the year. Late in the<br />
afternoon I saw one go down from a sunning mound, too distant for me<br />
to attempt a capture. This left me at one turtle for the year. *** the<br />
next day, 9 April, I was back in this favored overwintering place of<br />
the spotted turtles. Two went down from mounds before I could even see<br />
them (their rustling descents and rippling disappearances are<br />
unmistakable). After more than an hour (not a great span of time in<br />
terms of turtle searches) of wading with no further sign of a turtle I<br />
adopted my wait-and-watch mode, getting up on a mound of royal fern<br />
and alder that was firm enough to support me, and beginning a vigil. I<br />
went into something of my hydromancer&#8217;s trance, only turning my head<br />
very slowly now and then, to survey the narrow channels around me. My<br />
stillness was attested to by a chickadee&#8217;s approaching so closely I<br />
felt the wind from his wings on my ear&#8230; and the wonderful sound of<br />
flight. I was hoping he would land on me and attempt to pull out a<br />
hair or two for nest-building; this has happened to me twice, under<br />
similar situations. I remember well those tiny feet alighting first on<br />
my shoulder and then on the top of my head, and the tugging of my<br />
hair. I like to think that a strand or two came loose and became part<br />
of a nest. After perhaps twenty minutes, at three-thirty, a turtle<br />
appeared, a brilliantly marked male, proceeding along a channel<br />
directly toward me. At such times I recall a day in Vermont with good<br />
friend Steve Parren, Director of VT.,s nongame program. He had invited<br />
me to help him search for spotted turtles in the only know site (at<br />
the time) to support the species in the state. We separated out in an<br />
area of shrub swamps and vernal pools and at one point I took up my<br />
surveillance, sequestered among emergent buttonbush. At length Steve<br />
came wading along, saw me, and asked, &#8220;Are you waiting for them to<br />
come to you?&#8221;. He spoke in jest, but that is exactly what I was doing;<br />
this has worked for me, even on occasions when I was in wetlands brand-<br />
new to me, that suggested a spotted turtle presence. I waited until<br />
the turtle was directly below me to make my lunge, and found myself<br />
coming close to drinking the swamp as all around me gave way and both<br />
arms went full length down into water and mud, becoming braced only<br />
when my nose was at the surface. I unintentionally drove the poor<br />
turtle about a foot into the muck, and it was only with great effort<br />
that I extricated the two of us. The turtle was familiar male #108,<br />
one of those in this colony who features abundant, very large spots.<br />
My turtle for the day, #2 for the year. I am working hard for me<br />
turtles this season, and feel my years in these difficult habitats.</p>
<p>10 April: I made my first excursion to wood turtle territory, going to<br />
a fairly extensive alder thicket that is a key terrestrial riparian<br />
compartment for these turtles, especially at first emergence from the<br />
stream that borders it after hibernating there. Bank overflow does<br />
occur here, but unlike the Great Alder Carr the floodwaters do not<br />
inundate the entire shrub carr, and only inundate its brookside margin<br />
briefly with water barely ankle deep. I looked forward to the easier<br />
going of this habitat element, and seeing my first wood turtles of the<br />
new season. But as I descended the snow-covered slope from a high<br />
hayfield edge I saw that a great transformation had occurred.<br />
The alder zone was flooded right to the base of the upland rise;<br />
beavers had restored an old dam, a large one, and built a lodge among<br />
the alders, in a bit from the stream corridor. Luckily I had not gone<br />
with my idea of giving myself a bit of a break and not wearing waders,<br />
just some boots. (After the first three days, when the water<br />
temperature got to 40 degrees or a little above, I was able to switch<br />
from my neoprene to my gore-tex waders, making the going much less<br />
arduous.) I waded into the alder thicket, about knee-deep where I had<br />
expected to traverse a sun-flooded, leaf-strewn riparian zone in quest<br />
of basking wood turtles, who are generally within three meters of the<br />
water&#8217;s edge, and often directly at it. Turtles would have to swim for<br />
shore through extensive water considerably shallower than the brook<br />
itself, and then return to the deeper streambed for the night, vs,<br />
their habit of simply moving a short distance &#8211; or none &#8211; and dropping<br />
back into the stream. I took up a search of &#8220;islands in the stream&#8221;,<br />
recalling only two previous occasions when I had found a turtle on<br />
one. And this was in situations where spring spates would be short-<br />
lived; now this entire area would be flooded and entirely lost as<br />
highly favorable riparian terrestrial wood turtle habitat for as long<br />
as the beaver dam was maintained. And that could be for years. It is<br />
possible that humans might take out the dam, as they are wont to do,<br />
even in situations like this where the impoundment has no impact on<br />
dwellings, roads, agricultural, etc. interests. The great habitat<br />
constriction the wood turtles face now is exacerbated by the fact that<br />
the hayfield has been extended to essentially the very edge of the<br />
rise from the lowland wetlands, eliminating an ecotone that, again,<br />
much-favored these turtles during their long terrestrial phase. Such<br />
habitat has now been reduced to the lope itself, which is largely<br />
open, devoid of the vegetative tangles and layers (grasses, sedges,<br />
brambles, goldenrod, sweetfern, clematis, and the like) that are<br />
absolute requisites for these turtles. I wondered how any hatchlings<br />
who might have had their first overwintering in this stream-reach<br />
would fare; and the wood turtles in general. They all awakened to a<br />
vastly altered environment. &#8220;Brook trout&#8217;s world expands as wood<br />
turtle&#8217;s world constricts&#8221;, I thought.</p>
<p>The only lodgings for basking that were above water were the bases of<br />
some alder mounds, and these featured very limited purchases and<br />
virtually none of the cover required for the classic cryptic basking<br />
of the wood turtle. In my Lamprey River work of some years ago<br />
(1993-2003 or so) I did find wood turtles to emerge on something of<br />
&#8220;islands in the stream&#8221;, but these were more like barrier islands,<br />
linear holdfasts of silky dogwood of some extent in reach along the<br />
stream corridor, out from the riverbank. But I did find one wood<br />
turtle, a new-to-me three year old, who had taken a place in the sun<br />
on a crisscrossing of fallen pine trunk and branches (a few small<br />
struggling white pines do manage grow among the alders in the wet<br />
footing that is now submersed footing &#8211; they are likely to die out.)<br />
After my wading, I searched the slope, finding no turtles. I will<br />
return here, to attempt to come to some idea of how the wood turtles<br />
respond to this suite of significant human and natural (=beaver)<br />
transformations of a habitat element that has served them so well for<br />
at least a couple of decades.</p>
