Reptiles and Amphibians of the Packsaddle Wildlife Management Area

**For best viewing, please use Safari as your web browser**

   Packsaddle Wildlife Management area is located in Ellis County, Oklahoma adjacent (north) to the Canadian River. The habitat varies from sandy rolling hills and wooded canyons to river bottomlands. Upland sites contain mixed grass prairie plant communities, canyons contain riparian vegetation including mixed oak and cottonwood stands, and river bottom areas are dominated by cottonwoods, elms, and hackberries. More detailed information on the general habitat and area can be found at:

   The patchwork of habitats at Packsaddle provides habitat for a wide diversity of amphibians and reptiles, including mixed grass prairie species (e.g., Prairie Skinks), western species (e.g., Glossy Snakes), and eastern deciduous forest species (e.g., Brown Snakes). Consequently, it is an excellent place to see many species of amphibians and reptiles of Oklahoma in their natural habitat, especially during April, May, and June.

We surveyed amphibians and reptiles of the Packsaddle WMA during summer of 2006. We used a variety of techniques to observe and register amphibians and reptiles during our survey. They include haphazard searches through all habitats; drift-fence trapping with funnel and pitfall traps, hoop net trapping for turtles, night searching of ponds and the Canadian River, and road cruising for some nocturnal species. We established two sets of drift-fence arrays. Each array consisted of three plastic fences approximately 8 m in length with minnow traps on each side of each wing. Centrally placed pitfall traps were added after determining that no archeological or historic sites were present. Twenty arrays were established in two different drainage valleys extending on adjacent hillsides. Each array was monitored at least once per day over a 2.5 month period. We recorded all amphibians and reptiles trapped and released most animals at the site of capture. A drawing of the funnel trap array appears below as well as a photograph of an array.

   We documented six turtle species in 4 families, 8 lizard species in five families, 21 snake species in 3 families, 8 frog species in 5 families, and one salamander species. An additional five species (one frog and four snakes) are likely to be eventually found at Packsaddle. About a dozen species represent new distributional records for Ellis County and several represent significant range extensions for the species.

   Field work for this survey was conducted by the following researchers: Donald B. Shepard, Laurie J. Vitt, Janalee P. Caldwell, Gabriel C. Costa, Chris Wolfe (Sam Noble Oklahoma Museum of Natural History), Buddy Brown (Morris High School), and Tim Colston (University of Oklahoma). All field studies were conducted under the auspices of Scientific Collecting Permits (all participants) issued by the Oklahoma Department of Wildlife Conservation and an IACUC protocol issued by the University of Oklahoma. Voucher specimens and tissues collected during this study are deposited in the Herpetology Collection and the Genomic Resources Collection, respectively, of the Sam Noble Oklahoma Museum of Natural History in Norman.

No reptiles or ampibians are considered endangered and threatened in Oklahoma (see Threatened and Endangered Species of Oklahoma).
