Alligator Snapping Turtle Study Continues
Southwest Region, October 1, 2000
Print Friendly Version
Oklahoma State University research assistants sampling the historic range of the alligator snapping turtle for remaining turtles were excited to find one of the largest populations at Sequoyah NWR. As a listed species in the state of Oklahoma, the alligator snapper has suffered dramatic declines throughout its range. The refuge alligator snapper population became the focus of another study to mark and recapture turtles to better understand their population dynamics. To date, nearly 200 alligator snapping turtles have been captured, tagged, and released from the waters of Sequoyah NWR. Several individuals over 50 pounds and three turtles over 100 pounds have been marked from this population. During 2000, several individuals were fitted with transmitters to provide data regarding individual seasonal movements of this species. The population seems to be in great shape, researchers are enthusiastic that this population may serve as a source population for reintroductions in the future.
