Distribution and management of Alligator snapping turtles, Macrochelys temminckii, in Kansas and Oklahoma

The Alligator snapping turtle, Macrochelys temminckii, historically occurred in the Arkansas, Caney, Verdigris, Neosho, and Spring river drainages of northern Oklahoma and southern Kansas. High harvest rates in Oklahoma and river impoundments in both states have greatly reduced populations by decimating populations and impeding dispersal routes. Populations of M. temminckii are poorly studied in both states, but particularly so in Kansas. Management efforts for M. temminckii were initiated in Oklahoma in 1997 with the collection of information on distribution, habitat use, and population structure, and establishment of a captive breeding/headstart program. Management efforts in Oklahoma could have positive repercussions for M. temminckii in Kansas. We outline current knowledge of the species in both states, provide information on management efforts for the species in Oklahoma, and provide recommendations for interstate collaboration for managing the species in Kansas.
