The Selman Living Laboratory (SLL) is a potential refuge for a number of species including Arkansas Darter, Texas Horned Lizard, Peregrine Falcon, Lesser Prairie Chicken, Least Tern, Mexican Free-tailed Bat, and Swift Fox. The Cimarron Gypsum Hills are unique herpetologically in that some western species are more or less restricted to these hills. Approximately 230 plant species occur on the SLL. The Selman Cave System is the fourth largest cave in Oklahoma. It is the only cave located at a biological field station and is available for research and education.

The major categories of species at the SLL are listed below. The links list individual animals, invertebrates, and plants in the group.
