O’SHEA, CRYAN & BOGAN: UNITED STATES BAT SPECIES OF CONCERN 
173 
abandoned mines and tunnels in six habitat zones (Ports and Bradley, 1996). They ranked second 
in relative abundance (103 of about 2,000 bats) among 13 species captured foraging in four vege¬ 
tation zones (ranging from desert scrub to bristlecone-limber pine forests) in the White and Inyo 
Mountains of California and Nevada, and they were one of only two species of bats captured in the 
high elevation bristlecone-limber pine forests (Szewczak et al., 1998). This species ranked third in 
relative abundance at the Nevada Test Site (among more than 2,000 bats of 13 species netted over 
water), where nearly all (180 of 183) were netted in Great Basin Desert habitat (Hall, 2000). They 
ranked ninth (five captures among 299 bats of 11 species) in mist-netting surveys over water in 
west-central Nevada in habitats categorized in four vegetation zones but were only taken in the 
pinon-juniper woodland zone (Kuenzi et al., 1999). 
Southwestern U.S.: Arizona : The long-legged myotis was one of the most commonly cap¬ 
tured species of bats in ponderosa pine forests on the Coconino Plateau in northern Arizona at ele¬ 
vations ranging from 2,018 to 2,621 meters, where they ranked first among 15 species document¬ 
ed in a 1993-1995 study (400 among 1,673 individuals captured) but were disproportionately 
lower in relative abundance in mixed ponderosa pine-Gambel oak habitat at slightly lower eleva¬ 
tions within the larger study (Morrell et al., 1999). They were the most commonly captured species 
among 17 species of bats (321 captured of 1,171 total bats netted) taken over water mostly in pon¬ 
derosa pine and pinon-juniper habitats of the Arizona Strip in northwestern Arizona (Herder, 1998). 
Long-legged myotis ranked second in relative abundance (261 captures among 1,441 individuals 
of 14 species) captured in combined low severity and high severity bum areas (two and three years 
post-fire) of ponderosa pine forest at 2,345 to 2,686 meters elevation in the Apache-Sitgraves 
National Forests in east-central Arizona (Saunders, 2015). This species ranked fifth in relative 
abundance (268 captures among 3,458 individuals) of 17 species netted over water in Mohave 
County in western Arizona, but it was only captured at sites in or near higher elevation mountain 
habitats (Cockmm et al., 1996). Long-legged myotis ranked ninth in relative abundance (six bats 
among 353 individuals of 15 species) in ponderosa pine forests at 1,350 to 1,930 meters elevation 
along the East Verde River below the Mogollon Rim, on the Tonto National Forest in central 
Arizona (Lutch, 1996). A mist-netting survey in five riparian canyons in the Huachuca Mountains 
in southern Arizona during 1993 and 1994 found this species to rank eleventh in relative abundance 
among 13 species documented (two captures out of 145 individuals; Sidner and Davis, 1994). 
New Mexico : Long-legged myotis were the second most frequently captured (a total of 226) 
among 1,595 bats of 20 species taken in the Mogollon Mountains of western New Mexico and 
adjacent Arizona, where they were most abundant in evergreen forest above 2,134 meters (Jones, 
1965). In a separate analysis limited to three sites over water in western New Mexico and includ¬ 
ing additional years of sampling, they ranked third of 19 species (145 captures among 1,004 indi¬ 
viduals) and were taken at all three sites; habitat at capture sites ranged from riparian hardwoods 
at 1,465 meters to pine-spmce-fir forest at 2,620 meters elevation (Jones and Suttkus, 1972). In the 
Jemez Mountains of north-central New Mexico, they were intermediate in relative abundance, 
ranking fifth of 15 species (101 among 1,532 captures) and were netted over water at elevations 
ranging from 1,753 to 2,774 meters and habitats ranging from ponderosa pine to spruce-fir forests 
(Bogan et al., 1998). Echolocation activity of this species was commonly detected in riparian, 
conifer, pinon-juniper, and previously (20 years) intensely burned ponderosa pine habitat in the 
Jemez Mountains, but it was heaviest in riparian areas (Ellison et al., 2005). This species ranked 
second in relative abundance (48 among 302 bats of 10-11 species) netted in mostly ponderosa 
pine habitat at 2,600 to 2,885 meters on Mount Taylor in northern New Mexico (Geluso, 2008). 
Chung-MacCoubrey (2005) presented evidence that this species is commonly associated with 
both pinon-juniper woodlands (the fourth most abundant species taken in mist nets, with 118 cap-
