was arbitrarily assigned to three categories: low= 0-4 bat passes 

 per hour; moderate= 5-9 bat passes per hour; and high= 10 plus 

 bat passes per hour. 



No bat activity was recorded at only two sites surveyed (Foster 

 Creek and Elkhorn). The evening that Foster Creek was surveyed 

 had thunderstorms with wind and occasional heavy rain. 



Light bat activity (one to four bat passes per hour) was recorded 

 at five sites (25%). These sites included Lowland Campground, 

 Basin Creek, the Boulder River, Old Highway 10 east of Butte, and 

 the unidentified mine site several miles northeast of Basin 



(Table 1). 



Moderate activity (five to nine passes per hour) was recorded at 

 Stoney Creek Campground, Elder Creek Campground, the Douglas 

 Creek Mines, Queen's Gulch, French Gulch, the Mountain Lion Mine, 

 and the Eva May Mine (35% of the sites visited )( Table 1). 



Sites with high activity (10 or more bat passes per hour) were 

 Bison Creek, Brown's Gulch, Beaver Creek, Pigeon Creek, Pikes 

 Peak Creek, and Boulder Creek (30% of the sites) (Table 1). 



The number of sites surveyed that contained a given habitat 

 component, and the number and percentage of these sites that had 

 high, moderate, or low activity, is shown in Table 2. For
