We constructed an artificial nesting mound for Glyptemys insculpta (Wood Turtle) in the Great Swamp National Wildlife Refuge, NL The original nesting site was impacted by development and invasive plants. The new nesting mound was constructed from similar soil and was 100 m distant from the original site. The new mound was 50 m from stream habitat and in an old field where it received full sun for the entire day. The mound was 18 m long, 8 m wide, and had a maximum height of 1.5 m, with gently sloping sides. We encountered nest-searching female Wood Turtles on the impacted site during late May to early June for four years, 2007–2010. We carefully hand-carried females to the new nesting area and allowed them to choose whether or not to nest on the mound. We protected all nests from predators. Seventeen of 18 nests that were deposited and left on the nesting mound produced live hatchlings. Six clutches had 100% hatching success, with only one failing completely. At least nine different female Wood Turtles nested on the mound. One female returned on her own in three subsequent years, another returned on her own in one subsequent year, several were re-shown the mound in subsequent years, and one turtle found the mound and nested on it on her own. The nesting mound has produced 142 hatchling Wood Turtles over the four years. We suggest that it is possible to entice female turtles to nest in a new area and that when nesting resources are limited, construction and protection of nesting areas can be a useful conservation action.
