Virginia’s Threatened Wood Turtle
I had never seen a wood turtle (Glyptemys insculpta) before. Which is not all that surprising, even given my time spent in the woods. In Virginia, the wood turtle is a threatened species. It has been assigned the Virginia Wildlife Action Plan rating of Tier 1 — Critical Conservation Need, which means it faces “an extremely high risk of extinction or extirpation. Populations of these species are at critically low levels, facing immediate threat(s), or occur within an extremely limited range. Intense and immediate management action is needed.”
My friend, naturalist Brian Balik has seen a few over the years, and knew of their decline in Virginia. So when he recently happened across two wood turtles in the same location in Northern Virginia, at first he couldn’t believe what he was seeing. “Spotting a threatened wood turtle ranks as a top experience in my life as a naturalist,” Brian said. “It’s something I am definitely not taking for granted, especially living in an area where there are very few of them.”
He took some photos of that first wood turtle and kept hiking, only to find another less than 100 yards away. So knowing there were at least two in the area, we set out a couple weeks later to hopefully re-find them so I could get some photographs. I was less confident than Balik, as I have a history of not being able to find things, but lo and behold, after hiking a few miles adjacent to a creek bed, Brian called out. “Turtle!” I couldn’t believe he had found one again! It was an extremely special sighting.
Just how rare is the wood turtle in Virginia? I contacted J.D. Kleopfer, a Herpetologist for the Virginia Department of Game and Inland Fisheries, who was excited about the find. “Not too many woodies left in that part of the world,” he said. “So any observations are critical.”
The turtle measured around eight inches long, was gentle and even a little curious. We spent a little time observing and photographing this affable little creature who cooperated for quite a while before deciding to wander off in search of lunch, privacy or both. But we were happy with the encounter and the photos we captured, so we left her and continued exploring, spotting some toads, a beautiful skink and even a yellow jacket nest along the way. (Balik is also better at finding yellow jackets than I am.)
I shared my photos with Ellery Ruther, Lead Field Technician of Virginia Working Landscapes for the Smithsonian Conservation Biology Institute, who graciously provided some information about the turtle we encountered. “At first glance, I thought this animal was a small female,” she said. “But after counting the annuli (rings on the shell) to estimate age, it looks like the turtle is a juvenile around 8 years old. Wood turtles don’t reach maturity until around 10-15 years of age.” They can live up to 60 years.
We did not closely examine our sample turtle (nor would I have known what to look for), but Ruther explains that the best way to tell sex would be to look at the bottom of the shell. “Males have concavity, and females are flat,” Ruther said. “Otherwise, females generally have smaller heads, smaller front claws, and smaller tails than males do.”
As with many threatened species, urban and agricultural development have been among the biggest contributors to wood turtle decline. “Wood turtles are semi-aquatic, so they rely on both terrestrial and aquatic environments, can occupy relatively large home ranges, and often move between watersheds,” Ruther said. “All of which makes them very sensitive to development.” In addition, these factors lead to increased predator encounters, mortality crossing roads and, perhaps most disturbingly, accessibility for poachers.
Kory Steele, President of the Virginia Herpetological Society, warns the public about removing animals from the wild. Once he was brought a wood turtle that was picked up on the road by someone vacationing in their range and brought home. He discovered it was a gravid female. “One of the important individuals in that population had been removed,” Steele said. “It emphasizes that turtles should NOT be picked out of the wild for pets.”
And it’s not just rare and threatened turtles that are put at risk by poaching. “Box turtles in particular are taking a big hit because of removal for pets,” Steele said. “Most box turtles at rescues are unwanted pets that were originally wild.”
If you happen to come across a rare or threatened specimen like Virginia’s wood turtle, Balik recommends taking a few photos and reporting the sighting to VDGIF. “Or if you are in a park land, report the sighting to park staff,” he said. “Keep in mind exactly where you are, nearby water bodies, road intersections, date, time and a photo.”
So please just enjoy Virginia’s precious wildlife where you find it. As the old maxim goes, “take nothing but pictures, leave nothing but footprints.”
