surrounded by cottonwoods situated in a sagebrush dominated 

 valley (Figure 2). Myotis species were heard on the bat detector 

 at most sites surveyed on the Deerlodge National Forest in 1992. 

 Myotis were almost always the most abundant bats present (they 

 were not heard at one site where other bat species were; the Eva 

 Mae Mine northeast of Basin). 



Long-eared myotis (Myotis evotis) were captured at two sites in 

 1992 on the Deerlodge N.F.; near the Douglas Creek mines and on 

 Pikes Peak Creek. Both sites are riparian, have caves or adits 

 nearby, and have mature Douglas fir in the vicinity (Figure 2). 



A Small-footed myotis (Myotis ciliolairum) was captured near 

 the adits, and observed exiting from them, at the Douglas Creek 

 mines (Figure 2). 



Fringed myotis (Myotis thysanodes) were captured at Queen ^ Gulch 

 and Beaver Creek in 1992 (Figure 2). Both of these sites were 

 near streams and riparian vegetation in mature Douglas fir 

 forests. There are rock outcrops nearby in Queen •'^ Gulch, and 

 beaver ponds and extensive willow stands on Beaver Creek. 



Big brown bats ( Eptesicus fuscus ) were captured in mist nets at 

 the Douglas Creek mines in 1992, and at Queen •% Gulch in the 

 Elkhorn Mountains east of Boulder in 1991. They were also 

 observed, and heard on bat detectors, at the Mountain Lion Mine
