Yuma Myotis Myotis Yumanensis
Wyoming Species Account Yuma Myotis Myotis yumanensis REGULATORY STATUS USFWS: No special status USFS R2: No special status USFS R4: No special status Wyoming BLM: No special status State of Wyoming: Nongame Wildlife CONSERVATION RANKS USFWS: No special status WGFD: NSS4 (Cb), Tier III WYNDD: G5, S1 Wyoming Contribution: LOW IUCN: Least Concern STATUS AND RANK COMMENTS Yuma Myotis (Myotis yumanensis) has no additional regulatory status or conservation rank considerations beyond those listed above. NATURAL HISTORY Taxonomy: There are six recognized subspecies of Yuma Myotis 1. Because of distributional uncertainties, it is unclear which subspecies occur in Wyoming. In general, the subspecies M. y. yumanensis occurs in the southern Rocky Mountains, while M. y. sociabilis occurs in the northern Rocky Mountains 1, 2. Description: Yuma Myotis may be difficult to identify in the field, even by skilled observers. The species is a small vespertilionid bat, but medium in size among bats in the genus Myotis. Pelage color is variable across the species’ range. Dorsal fur is short, dull, and varies from gray and brown to pale tan in color. Ventral fur is lighter in color, white or buffy. The ears, wing, and tail membranes are pale brown to gray 1. Males and females are identical in appearance, but females may be significantly larger than males in some populations 1. Juveniles are similar in appearance but can be differentiated from adults by the lack of ossified joints in the phalanges for the first summer 3, 4. Yuma Myotis is similar in appearance to other co-occurring Myotis species. Yuma Myotis can be distinguished from Long-legged Myotis (M. -
Lower Colorado River Bat Monitoring Protocol
LOWER COLORADO RIVER BAT MONITORING PROTOCOL Patricia Brown, Ph.D. January 2006 INTRODUCTION AND BACKGROUND European man has drastically changed the natural habitat of the Lower Colorado River (LCR) over the past 150 years. Dams for power, flood control and water export; bank stabilization and channelization have altered the flow and flood patterns, salinity and plant communities of the LCR. The destruction of the native vegetation, most notably the cottonwood/willow riparian, and its replacement by exotics, especially salt cedar continues unabated. Over the past 50 years, declines have been observed in some bat species, such as the cave myotis (Myotis velifer) and Townsend’s big-eared bat (Corynorhinus townsendii), that were at one time relatively abundant along the LCR. Large deposits of the distinctive guano of these colonial species are found in abandoned mines that border the LCR, although the bats are now absent or present in very small numbers. Only four maternity colonies of cave myotis and one maternity colony of Corynorhinus are now known along the LCR. The Arizona myotis (Myotis occultus) appears to have disappeared from the LCR, with the last museum specimen collected in 1945. The type locality for this species was Ft. Mojave north of Needles. One hypothesis for the decline of some bat species is the removal and replacement of native floodplain vegetation that supported the insect diets of these bats. Another is the heavy pesticide spraying in agricultural areas (conducted principally at night) that directly reduces the preybase and indirectly poisons the bats. A third possible cause is the disturbance of roosts of colonial bat species by the increased resident and recreational human population along the Colorado River. -

Life History Account for Yuma Myotis
California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group YUMA MYOTIS Myotis yumanensis Family: VESPERTILIONIDAE Order: CHIROPTERA Class: MAMMALIA M023 Written by: J. Harris Reviewed by: P. Brown Edited by: S. Granhom, R. Duke DISTRIBUTION, ABUNDANCE, AND SEASONALITY The Yuma myotis is common and widespread in California. It is uncommon in the Mojave and Colorado Desert regions, except for the mountain ranges bordering the Colorado River Valley. Found in a wide variety of habitats ranging from sea level to 3300 m (11,000 ft), but it is uncommon to rare above 2560 m (8000 ft). Optimal habitats are open forests and woodlands with sources of water over which to feed. SPECIFIC HABITAT REQUlREMENTS Feeding: Feeds on a wide variety of small flying insects found by echolocation. This species usually feeds over water sources such as ponds, streams, and stock tanks. Prey includes moths, midges, flies, termites, ants, homopterans, and caddisflies (Easterla and Whitaker 1972, Black 1974, Whitaker et al. 1977, 1981). The Yuma myotis is an efficient forager, sometimes returning to the roost with a full stomach 15 min after dusk (Barbour and Davis 1969). These bats respond to temporary patches of prey, such as ant swarms (Vaughan 1980), although many authors report that regular foraging routes are followed. Cover: The Yuma myotis roosts in buildings, mines, caves, or crevices. The species also has been seen roosting in abandoned swallow nests and under bridges. Separate, often more open, night roosts may be used. Reproduction: Maternity colonies of several thousand females and young may be found in buildings, caves, mines, and under bridges. -
Habitat Partitioning of Bat Communities in Northern California
Habitat partitioning of bat communities in Northern California Paige Klotz1, Vanessa Lundsten2, Nic Morat3, Kenna Sherman4 1University of California, Merced, 2University of California, San Diego, 3University of California, Riverside, 4University of California, Santa Barbara ABSTRACT The theory of niche partitioning states that species coexisting at equilibrium within a stable community must share limited resources (Hutchinson 1957). This theory has been widely studied in diverse community assemblages, but few studies have applied niche partitioning to bat communities. Specifically, little is known about how bat species occupy different microhabitats in order to coexist. Our study aims to understand the effect of habitat on bat diversity and abundance within the scope of niche partitioning. To observe the difference in bat assemblages across varying habitats, we identified bat species diversity and abundance using acoustic detection in three different habitats (meadow, forest, and river). We used light traps to survey invertebrates as a measure of abundance throughout the night. Bat calls were most frequent at the river, where Yuma myotis (Myotis yumanensis) dominated. Hoary bats (Lasiurus cinereus) dominated the meadow. Overall, bat activity was lowest in the forest. As time progressed through the night, bat activity decreased at all sites, particularly in the meadow. We also observed ten times more invertebrates in the meadow compared to the other sites. Although the diet of generalist foraging bat species may overlap, species appear to partition into different habitats, possibly to avoid competition and coexist. Understanding more about bat community composition and activity may be useful in protecting this declining guild of mammals.

U.S. Geological Survey Response to White-Nose Syndrome in Bats
U.S. Geological Survey Response to White-Nose Syndrome in Bats Overview Since its discovery in 2007, the fungal disease known as white-nose syndrome (WNS) has killed more than six million bats. Ten of 47 bat species have been affected by WNS across 32 States and 5 Canadian Provinces. The cold-growing fungus (Pseudogymnoascus destructans) that causes WNS infects skin covering the muzzle, ears, and wings of hibernating bats. The fungus erodes deep into the vitally important skin of bat wings and fatally Big brown bat (Eptesicus fuscus) Cave bat (Myotis velifer) disrupts hibernation of bats through physical damage Ann Froschauer, USFWS Public Domain, NPS and energy depletion as they try to cope with infection. U.S. Geological Survey (USGS) science has been critical in identifying the causal fungus, characterizing the effects of WNS, and tracking the fungus as it rapidly spreads through many populations of bats in North America. Early USGS research enhanced our understanding of how WNS affects individual bats and how the fungus persists in the environment.

Appendix J Wildlife Reports
Appendix J Wildlife Reports To: Linda Cope, Wyoming Game and Fish Department From: Kim Chapman & Genesis Mickel, Applied Ecological Services Date: June 14, 2017 Re: Memo on new surveys requested by Wyoming Game & Fish Department _____________________________________________________________________________________ AES biologists have been collecting baseline biological data and recording incidental observations for the Boswell Springs Wind Project between 2011 and 2016 in consultation with Wyoming Game and Fish Department (WGFD) and U.S. Fish and Wildlife Service (USFWS). During a Project meeting on May 26, 2017 and follow-up letter dated June 5, 2017, staff at the WGFD requested targeted surveys for four species of interest to better assess their presence or absence in the Project area. The four species are black-footed ferret, swift fox, mountain plover, and long-billed curlew. The purpose of this memo is to summarize the survey methodology presented and accepted by WGFD on a June 12, 2017 conference call. 1. White-tailed prairie dog activity areas. Incidental sightings or evidence for black-footed ferret, swift fox, and mountain plover, have been isolated to areas identified as high-density for prairie dog burrows. As a result, the first task is to refine the mapping of the prairie dog colonies and field verify the high- activity areas. The resulting high-activity areas will then be used to survey for presence or absence of these species. Prairie dog burrow densities were originally mapped in the Project area from aerial photos, which were then ground-truthed along transects. The resulting map indicated areas of burrows at high, moderate, and low densities, but did not pinpoint the areas where prairie dogs were most active.
