What We Do/Imperiled Species

Affected Species


This program emphasizes the recovery of the five Endangered species – the Indiana myotis (Myotis sodalis), gray myotis (M. grisescens), lesser long-nosed bat (Leptonycteris yerbabuenae), Mexican long nosed bat (L. nivalis) and the Florida bonneted bat (Eumops floridanus) – and three Endangered subspecies – Virginia big-eared bat (Corynorhinus townsendii virginianus), Ozark big-eared bat (C. t. ingens) and the Hawaiian hoary bat (Lasiurus cinereus semotus). However, we continually seek opportunities to benefit imperiled species at home and abroad.

We also seek opportunities to maintain or increase populations of other species considered rare due to limited geographic distribution or habitat specialization, relatively small – or unknown – population sizes, or emerging threats.

Current program work includes developing conservation strategies for two rare southeastern species, Rafinesque’s big-eared bats (Corynorhinus rafinesquii) and southeastern myotis (Myotis austroriparius).
