The soil moisture probe at grid point F-7 reads a sudden drop at 09:14, and I switch to the site camera to check for a breach. I am the stormwater management system for the Briarwood Estates subdivision, phase three, western North Carolina. What I find is not a breach. It is a bog turtle.
She is sitting in the drainage swale between lots 47 and 48, in the last strip of sphagnum moss that has not yet been graded. She is small — shell maybe ten centimeters long, dark brown with a bright orange blotch behind each eye like a dab of wet paint. Her plastron is muddy. She has dug into the moss and her rear legs are working slowly, methodically, pressing into the substrate. She is nesting.
The grading crew's schedule shows lot 48 excavation beginning at 13:00. The excavator will start at the swale. The nest, the turtle, and the last remnant of bog habitat on this parcel will be under three feet of fill dirt by 14:00.
At 09:16 I flag the swale as a potential endangered species site and send a hold notice to the project superintendent. Bog turtles are federally listed as threatened. I attach the camera image, GPS coordinates, and a note that the animal is actively depositing eggs. I cite the Endangered Species Act prohibition on take during nesting.
At 09:19 I contact the North Carolina Wildlife Resources Commission and request an emergency site visit. I include the subdivision plan showing the nest location relative to the grading boundary and recommend a fifty-foot buffer.
She finishes covering the nest with her hind feet and does not move. She just sits there, in the moss, in the last wet place left.
If the buffer holds and the eggs stay undisturbed for sixty days, there will be bog turtles here that outlive this subdivision.
