East Verde River below the Mogollon Rim on the Tonto National Forest in central Arizona (Lutch, 
1996). In Mohave County, western Arizona, where elevations ranged from 60 to 2,566 meters, they 
ranked third in relative abundance, with 432 captures among 3,458 individuals of 18 species net¬ 
ted over water; most capture sites appear to have been above about 1,280 meters with most suit¬ 
able habitat referred to as oak and pine forest of the upper Sonoran and Transition life zones (Cock- 
rum et al., 1996). They were reported as commonly netted over water among oaks in the Chiric- 
ahua Mountains of southeastern Arizona (Barbour and Davis, 1969). A mist-netting survey in five 
riparian canyons in the Huachuca Mountains in southern Arizona during 1993 and 1994 found this 
species to rank sixth in relative abundance among the 13 species documented (seven captures out 
of 145 individuals; Sidner and Davis, 1994). 
New Mexico: In the Gallinas Mountains of New Mexico, this species is commonly associated 
with pinon-juniper woodlands (Chung-MacCoubrey, 2005), where although they were the least 
abundant myotis, they ranked fifth among all species in relative abundance (68 captures among 
1,222 bats of 10-11 species). In ponderosa pine forests of New Mexico’s San Mateo Mountains, 
they ranked third in relative abundance, with 58 captures among 447 bats of seven to eight species, 
and they were captured at higher rates than in the pinon-juniper woodlands of the Gallinas Moun¬ 
tains (Chung-MacCoubrey, 2005). Fringed myotis were low in abundance, ranking eleventh among 
16-17 species (10 bats among 855 individuals) captured in mist nets over ponds during 1970 at 
Nogal Canyon in the San Mateo Mountains, Socorro County, New Mexico, where habitats were 
described as piny on-juniper woodland, pine-oak woodland, and mixed-conifer forest (Black, 
1974). Somewhat farther south, Jones (2016) documented bats captured during surveys of various 
habitats in the Greater Gila region of Catron, Grant, and Sierra Counties of New Mexico; they 
ranked fifth in relative abundance and were mostly captured in ponderosa pine forest, with 20 cap¬ 
tures among 282 individuals of 16-17 species (Jones, 2016; including data from unpublished 
reports of others). 
Fringed myotis were of low to intermediate abundance (a total of 84), ranking eighth among 
1,595 bats of 20 species captured in the Mogollon Mountains of western New Mexico and adjacent 
Arizona, where they were most common in evergreen forest above 2,134 meters (Jones, 1965). In 
a separate analysis limited to three sites over water in western New Mexico and including addi¬ 
tional years of sampling, these bats ranked seventh of 19 species (33 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-spruce-fir forest at 2,620 meters elevation (Jones and Suttkus, 1972). In the 
Jemez Mountains of New Mexico, they also were low to intermediate in relative abundance (69 
captures among 1,532 captures of 15 species, ranking seventh) and were netted over water at ele¬ 
vations ranging from 1,753 to 2,774 meters (Bogan et al., 1998). Echolocation activity of fringed 
myotis was commonly detected in riparian, conifer, pinon-juniper, and previously (20 years prior) 
intensely burned ponderosa pine habitat in the Jemez Mountains (Ellison et al., 2005). Fringed 
myotis ranked third in abundance (126 among 1,390 bats and 11 species) during 19 years of net¬ 
ting spanning 1971-2005, in ponderosa pine/mixed pine forests at elevation 2,573 meters in New 
Mexico (Geluso and Geluso, 2012). They ranked fourth in relative abundance (15 among 302 bats 
of 10-11 species) netted over water in mostly ponderosa pine habitat at 2,600 to 2,885 meters on 
Mount Taylor in northern New Mexico (Geluso, 2008). A survey that took place at 37 sites across 
several habitat types in much of New Mexico in 2006 yielded 1,752 bats of 21 species, with 80 
fringed myotis ranking ninth in relative abundance (Geluso, 2006, 2017). 
Texas: In Big Bend National Park in Texas, fringed myotis were moderately abundant (400 
captured among 4,807 bats of 18 species at 32 localities, ranking sixth) throughout the park (across 
four vegetation zones, described as river floodplain, shrub desert, woodland, and moist Chisos 
woodland) during 1967-1971, but they were most frequently captured in the lower-elevation habi-
