Disclaimer:

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.

Common name: False Map Turtle

Taxonomy: available through www.itis.gov

Native Range: Texas, Louisiana, Mississippi and Arkansas north along the Missouri, Mississippi, and Ohio river drainages to North Dakota, Minnesota, Wisconsin, Illinois, and Indiana. Isolated populations occur in central Ohio and northern Indiana (Ernst et al., 1994; Conant and Collins, 1998).

Alaska	Hawaii	Puerto Rico & Virgin Islands	Guam Saipan

Hydrologic Unit Codes (HUCs) Explained
Interactive maps: Point Distribution Maps

Means of Introduction: Pet releases.

Status: Reported in Virginia.

Impact of Introduction: Negligible since the species is not established in Virginia (Mitchell, 1994; Ernst et al., 1997). Because G. pseudographica is omnivorous, eating mollusks, insects, crayfish, aquatic plants and more, an established population could influence the food web (Ernst et al., 1994).

Remarks: Habitat: Large rivers and backwaters, but also lakes, ponds and other wetlands (Ernst et al., 1994). Life History: Two to three clutches containing 2 to 22 eggs are laid from May to July. Females usually excavate nests in the morning or on overcast days on banks or beaches (Ernst et al., 1994).

Scientific and standard English names follow Crother (2008).
