Graptemys pseudogeographica, 124 - Tortoise and Freshwater Turtle Specialist Group

Distribution

USA. Occurs in the larger rivers of the Mississippi River Basin, from the St. Croix and Wisconsin Rivers in northern Wisconsin and the Mississippi and Minnesota rivers in Minnesota southward to Louisiana and westward into Missouri, Kansas, and Oklahoma, in the Missouri River northward into North Dakota, and in the Ohio River eastward into the lower Tennessee and lower Cumberland rivers in western Tennessee and Kentucky and the Wabash River in Indiana. Also occurs in isolated river drainages west of the lower Mississippi along the western Gulf Coast: the Mermentau, Calcasieu, Sabine, Neches, Trinity, Brazos, and San Bernard drainages in Louisiana and Texas.

Distribution of Graptemys pseudogeographica in the USA. Yellow dots = museum and literature occurrence records of native populations based on Iverson (1992), other more recent literature records (see TTWG 2017, 2021), and authors' additional data; orange dots = possibly introduced or translocated specimens; colored shading = estimated historical indigenous ranges of: 1) G. p. pseudogeographica = red, and 2) G. p. kohnii = blue; purple-colored overlap areas = presumptive intergrades. Distribution based on fine-scaled GIS-defined level 12 HUCs (hydrologic unit compartments) constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs based on Buhlmann et al. (2009), TTWG (2017, 2021), and data from authors and other sources.
