Ecology: The wood turtle inhabits wetlands, streams, and rivers, as well as meadows, forests, and farmlands adjacent to water (Ernst et al. 1994; Conant and Collins, 1998).
The species hibernates in water, and is most aquatic in the northern portion of its range (Ernst et al. 1994; Conant and Collins, 1998). Mating peaks in spring and fall and nesting occurs in May and June, when 4 to 18 eggs are laid in holes excavated in the soil (Ernst et al. 1994).
Means of Introduction: Pet release.
Status: Failed in Florida and Massachusetts.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
