|Scientific Name:||Pseudacris crucifer|
|Species Authority:||(Wied-Neuwied, 1838)|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer/s:||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This species occurs throughout the eastern USA and adjacent southeastern Canada (east to Labrador, Bergman 1999), west to Manitoba, Minnesota, Iowa, eastern Kansas, Oklahoma, and eastern Texas (Conant and Collins 1991). It is absent from southern Florida. It was formerly believed to have been introduced in Cuba (Schwartz and Henderson 1991), but it has not been found there (Powell and Henderson 1999).|
Native:Canada; United States

|Population:||There are thousands of populations and millions of individuals.|
|Habitat and Ecology:||Typically it is found in moist wooded areas, especially near breeding pools. The species is mostly terrestrial and it hides under logs, rocks, or other objects when inactive. Eggs are laid and larvae develop in small temporary or permanent waters of ponds (including those in fields with nearby forest), marshes, ditches, and swamps, especially those with standing plants, sticks, or other debris. Males call usually from among herbaceous vegetation adjacent to or standing in water. In northern Minnesota, successful reproduction in acidic bog water either does not occur or is a rare event (Karns 1992).|
|Major Threat(s):||Wetland drainage reduces the available habitat. It does not thrive in areas of urbanization and intense agriculture, but the species is moderately adaptable. However, the species does not face major threats on a global scale.|
|Conservation Actions:||There are no conservation methods needed. It occurs in many protected areas.|
