State Protection: Endangered
A native species in imminent danger of extirpation or extinction in New York (includes any species listed as federally Endangered by the United States). It is illegal to take, import, transport, possess, or sell an animal listed as Endangered, or its parts, without a permit from NYSDEC. 1) Any native species in imminent danger of extirpation or extinction in New York. 2) Any species listed as endangered by the United States Department of the Interior.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
Eastern mud turtle hatchlings have a red-orange bottom shell (plastron); the scientific name of the species refers to this characteristic (Gibbs et al. 2007).

State Ranking Justification [-]
The eastern mud turtle is the rarest turtle species in New York. The species is rare in New York because of its limited distribution, small number of populations, and low numbers of individuals. It is limited to Long Island and nearby islands, which represent the extreme northeastern edge of its U.S. range (Ernst and Barbour 1972). Since 1990, eastern mud turtles have been documented at only seven wetland complexes in the state (New York Natural Heritage Program 2010). The largest and most secure population contained approximately 68 marked turtles in 1996 (Larese-Casanova 1997; Soule 1997), the next largest is currently estimated at 35 individuals, and the rest appear to be much smaller or have been insufficiently surveyed (Soule and Lindberg 2008).
