Fox Island Marsh Conservation Area Welcomes Endangered Babies

Sunday, September 14th, 2008

The Fox Island Marsh Conservation Area lies in South Wellfleet and, along with its neighbor the Pilgrim Spring Woodlands Conservation Area, comprises 68 acres of woods and 100 acres of salt marsh.  An exquisite parcel of these conservation lands is the Whale Bone Point Trail (see Google image below) described as the jewel in the crown for its unmatched overlook views of the Fox Island Marsh and Blackfish Creek.  These lands are owned by the Town of Wellfleet and the Wellfleet Conservation Trust.

Whale Bone Point

This last week the Fox Island Conservation Area witnessed the arrival of babies from two Massachusetts protected species: diamondback terrapins (threatened) and Eastern box turtles (species of special concern).  While the Whale Bone Point area had been assessed as box turtle habitat and the point has been documented as a terrapin nesting site, these are the very first babies of both species that have actually been discovered on the land as they were being born.   The conservationists, environmentalists and naturalists who worked to protect this precious habitat deserve two thumbs up, one for each of these listed species.

One of Four Eastern Box Turtle Hatchlings

Last week a resident abutting the Whale Bone Point area discovered four Eastern box turtle hatchlings in a nest in her mulched landscaping.  That story was reported below under Eastern Box Turtle Hatchlings.  These adorable babies were a bit disoriented, one might even say “grumpy,” at being so uncerimoniously disturbed from their post-natal snooze, and they were a little dehydrated, too.  So, after a few days of turtle R&R, the foursome was released into the protected woodlands of Whale Bone Point near their nest site.

Release of Eastern Box Turtle Hatchlings

After releasing these box turtle hatchlings on Friday, we trekked down to the tip of Whale Bone Point where we had documented diamondback terrapin nesting since 2000 based on depredated nests and discarded egg shells.  We discovered three emergence holes within about 12 inches of each other that contained the remnants of escaped hatchlings, undeveloped eggs and some eggs that had been destroyed by root and insect predation.  In the middle nest, tucked under the lip and cradled in roots that had drained moisture from the nest and had contorted the embryos inside their egg shells within their nose-like grip, three pipped and cracked eggs remained.  One had not survived the attack, but two others were alive, albeit distorted, severely dehydrated and frozen in a trance-like stupor.  The clip below documents our removal of one of these hatchlings from its egg cocoon; the babies were so weak that they couldn’t free themselves from the dried egg shell and dig themselves out of the nest.

Rescue of Terrapin Hatchling Trapped by Roots and Dehydration

You can see from the clip above how undersized these hatchlings are.  The image below gives you a good sense of their actual size.

Undersized Terrapin Hatchlings

The good news:  Terrapins (and most turtles, actually) are Timex critters.  “They take a licking and keep on ticking.”  Turtles are extremely resilient.  Given a little TLC, even the most hapless turtle can be given a head-start toward survival.  These two babies just need a few days of care before they, too, will join their siblings in the nursery salt marsh abutting the Fox Island Marsh Conservation Area.  And in about eight years … Mark your calendar for June 15th, 2016 … they may be returning to Whale Bone Point to deposit their own nest of hatchlings.  And so the cycle goes on.  Save one turtle and your action ripples through the ages.  Precisely like the “Time Machine” that Nature truly is.

Confronting Maggot Infestation in Wareham Turtle Garden

Saturday, September 13th, 2008

As we described earlier in the post, “Rescuing Live Hatchlings from Maggot Infested Nests,” fly maggots devastate threatened diamondback terrapin nests on the Outer Cape.  They devour tiny, vulnerable hatchlings as they break their eggshells in the secret darkness of their hidden underground nests.  When we encounter a nest infested with maggots, and after we suppress our disgust and repulsion, we aggressively excavate the egg chamber in order to save as many hatchlings as we can.

Terrapin Egg Completely Consumed by Fly Maggots

This Thursday we checked on a nest laid late last June in a new turtle garden off Broadmarsh River in Wareham, 60 miles from nests on the Outer Cape and on the other side of the Cape Cod Canal.  Still, once we penetrated the egg chamber the sand resembled an Indiana Jones movie scene with maggots playing the role of snakes.  “Maggots,” exclaims the Turtle Guy.  “Why does it have to be maggots?”

We ignore the stench and dig quickly through the slithering sand to rescue eight live hatchlings among the devoured remains of eggs and embryos of seven might-have-been siblings. 

Eight Saved, Seven Depredated by Maggots

The rescued hatchlings appeared lethargic as though traumatized by the experience.  But after an overnight stay in clean, moist soil, and a leisurely bath in warm fresh water, they were eager for release into the wild.  That is, turtle eager which isn’t quite the same thing as mammal eager.

Hatchling Strolls through Wareham Turtle Garden

The background of the previous video clip shows the exquisite nesting habitat that was created by private homeowners abutting the nursery salt marsh of Wareham’s Broadmarsh River off Buzzards Bay.  At their own initiative and their own expense, the homeowners petitioned the Town of Wareham Conservation Commission for permission to create a perfect nesting habitat along a beach front that had become sand starved over the years and had lost all upland nesting potential.  These generous homeowners ordered 20 tons of perfectly matched beach sand to make a large nesting site at least 10 inches deep for terrapins to place their clutches.  Within a couple of weeks of completing this turtle garden, the first female terrapin had scratched and dug her nest.  In total, six nests were deposited in the new sandy turtle garden … all of which were protected by predator excluders.  As these new babies mature, they too will return to this turtle garden, ensuring a whole new generation of diamondback terrapins in Broadmarsh River; all thanks to an exceptional family who are dedicated to restoring the Wareham coastal ecosystem for future generations.

Release of Little Dude

Saturday, August 9th, 2008

“Litte Dude,” a threatened diamondback terrapin, emerged on August 23rd, 2007 with 16 more live siblings from a nest on the Assonet Bay Shores Beach in Freetown. He weighed 6.6 grams at emergence, measured a smidgeon over an inch long and sported a large, pinkish yolk sac. His siblings were released within a week, but this character was “the runt of the litter,” and would not likely have survived. Overwintering with the National Marine Life Center in Buzzards Bay, “Little Dude” grew to hockey puck size and was released today, August 9th, 2008 back into his natal habitat. Carl Brodeur & the Assonet Bay community, the NMLC team and Sue Wieber Nourse of Cape Cod Consultants released “Little Dude” at 2:30 pm this afternoon (August 9th, 2008).
