Status and Management of Endangered Bats in Arkansas

Three taxa of cave bats in Arkansas are listed as endangered: the gray bat {Myotis grisescens), the Indiana bat (M. sodalis) and the Ozark big-eared bat (Corynorhinus townsendii ingens). All occur primarily in the Ozark Plateau region of the northwestern and northcentral portion of the state. Population monitoring and ecological studies of endangered bats inhabiting important hibernation, summer, and transient caves were conducted annually since 1978.

Endangered Chiroptera of the Southeastern United States

Biologists consider four southeastern United States bat taxa to be endangered (in danger of extinction throughout all or a significant portion of their range). They are Myotis sodalis (Indiana bat), Myons grisescens (gray bat), Plecotus townsendii virginianus (Virginia big-eared bat), Plecotus townsendii ingens (Ozark big-eared bat). Causes of population declines include loss of habitat, direct killing, and disturbances to hibernating and maternity colonies.
