The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

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.
