tured in combined low severity and high severity burn areas (two and three years post-fire) in pon- 
derosa pine forest at 2,345 to 2,686 meters elevation in the Apache-Sitgraves National Forests in 
east-central Arizona (Saunders, 2015). They ranked eleventh in relative abundance (three 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 Ari¬ 
zona (Lutch, 1996). This species ranked eleventh in abundance among 15 species (17 bats captured 
among 1,673 individuals) netted over water in ponderosa pine and ponderosa pine-Gambel oak 
woodlands at 2,200 to 2,600 meters elevation on the Coconino Plateau of northern Arizona during 
1993-1995 (Morrell et al., 1999). 
New Mexico: Eighty-six western small-footed myotis (79% male) were captured over ponds, 
streams, and along cliff faces at 10 sites in the Jemez Mountains of New Mexico, ranging from 
1,753 to 2,729 meters elevation and including pinon-juniper woodland, ponderosa pine, and mixed 
conifer forests; this was the sixth most frequently captured species among 15 species and 1,532 
bats netted in the region during 1995-1997 (Bogan et al., 1998). Echolocation activity of these bats 
in the Jemez Mountains was commonly detected in riparian, conifer, pinon-juniper, and ponderosa 
pine habitat that had intensely burned 20 years earlier (Ellison et al., 2005). They ranked fourteenth 
in relative abundance (35 captures among 1,595 bats of 20 species) in the Mogollon Mountains of 
western New Mexico and adjacent Arizona, where they were most often captured in woodlands and 
evergreen forest above 1,524 meters (Jones, 1965). In a separate analysis limited to three sites over 
water in western New Mexico and including additional years of sampling, they ranked tenth of 19 
species (14 captures among 1,004 individuals) and were taken at all three sites; habitat at capture 
sites ranged from riparian hardwoods at 1,465 meters to pine-spruce-fir forest at 2,620 meters ele¬ 
vation (Jones and Suttkus, 1972). One of these bats was captured in a survey documenting 6 species 
and 130 individuals netted over water in riparian habitat along the middle Rio Grande in the 
Bosque del Apache National Wildlife Refuge in central New Mexico, within a broader Chihuahuan 
Desert landscape (Chung-MacCoubrey, 1999). 
Texas: This was the least abundant bat among 18 species captured across all habitats at Big 
Bend National Park in southwestern Texas, with a single bat taken (in woodland habitat) among 
4,807 individuals (Easterla, 1973). None were captured in a subsequent study during 1996-1998 
emphasizing lowland habitats at Big Bend National Park (among captures of 1,978 bats of 17 
species; Higginbotham and Ammerman, 2002). They also ranked least abundant out of 14 species 
(one out of 542 individuals) captured in mist nets that sampled at 108 locations over water in north¬ 
ern Chihuahuan desert habitats at Big Bend Ranch State Park in the Trans-Pecos region of Texas; 
the single bat was captured over a small pool in a sparsely vegetated area within a canyon (Yancey, 
1997). They were low in relative abundance (four captures out of 1,329 individuals in 12 species, 
ranking ninth) among bats captured in mist nets set over water at Palo Duro Canyon State Park in 
the Texas Panhandle, where habitats consisted of mesquite (Prosopis glandulosa ) -juniper associ¬ 
ations, grasses, cacti, and a riparian zone of cottonwood (Populus deltoides) and salt cedar ( Tamar- 
ix ramosissima) set within sandstone, shale, and limestone canyon walls (Riedle and Matlack, 
2013). 
Central Rocky Mountains and Western Great Plains: Colorado: Western small-footed 
myotis ranked as the second most abundant species (72 captures among 546 bats of 11 species) 
captured over stock ponds during surveys in pinon-juniper woodland at about 2,100 meters eleva¬ 
tion in the Uintah Basin of Moffat County in northwestern Colorado during 1979-1981 (Freeman, 
1984). They ranked lower in abundance in other areas of Colorado. These bats were intermediate 
in abundance at Mesa Verde National Park in southwestern Colorado (fifth most frequently cap¬ 
tured species, but with males outnumbering females) during mist netting of 1,996 bats of 15 species 
in pinon-juniper woodland, ponderosa pine, and mixed conifer forests during 2006-2007 (O’Shea
