Survey for bats in the Los Alamos National Environmental Research Park, with special emphasis on the spotted bat, Euderma maculatum
To increase knowledge about the presence of endangered species and their habitat at the LANL, 3D/Environmental Services, Inc. conducted a mist net survey for bats on Laboratory lands. In addition to documenting the presence of threatened and endangered species, this survey was conducted to gain more knowledge about the diversity and distribution of the bat fauna existing on the Laboratory. There are 25 species of bats found in New Mexico, about 16 of which are likely to occur in the region of the Laboratory. Of particular interest was documentation of the presence of the spotted bat, Euderma maculatum. The spotted bat is listed as Endangered, Group 2 by the State of New Mexico, and is a Federal Candidate for listing as endangered. As such, conservation of this species and its habitat should be a management priority on the Laboratory. A total of 94 bats were captured in 16 net nights, between 30 June and 05 July 1992. Thirteen species of bats were caught during the study: Antrozous pallidus (pallid bat), 10.6 percent; Eptesicus fuscus (big brown bat), 10.6 percent; Lasionycteris noctivigans (silver-haired bat), 16 percent; Lasiurus cinereus (hoary bat), 11.7 percent; Myotis californicus (California myotis), 4.3 percent; M. evotis (long-eared myotis), 7.4 percent; M. leibii (small-footed myotis), 5.3 percent; M. thysanodes (fringed myotis), 13.8 percent; M. volans (long-legged myotis), 7.4 percent of the catch; M. yumanensis,(Yuma myotis), 5.3 percent; Pipistrellus hesperus (western pipistrelle), 1.1 percent; Plecotus townsendii (Townsend`s big-eared bat), 1.1 percent, and Tadarida brasiliensis (Brazilian free-tailed bat), 5.3 percent.
