Donald R. Russell Nature Preserve
Adair County, Oklahoma
In mid-1991, Don Russell donated two tracts of land in Adair County, Oklahoma, to the NSS to create a 20-acre biological preserve. There are several cave remnants and one major cave on the property. The main cave, Linda Bear Paw Cave, is used by a large colony of endangered gray bats (Myotis grisescens) and one of the cave remnants is a hibernaculum for a colony of Ozark big-eared bats (Corynorhinus townsendii ingens).
Because this property was acquired with the purpose of establishing a biological preserve, visitation is extremely limited. This is an extension of the longstanding policy of the previous owner.
