and 4 AM), or before sunrise, but so few bats were recorded that this 

 practice was abandoned. 



Habitats sanpled for bat activity were broken into several habitat 

 conponents for analysis. The ccitponents were: 



COMPONENT CODE 



Etense lodgepole pine forest Lpp 



Mixed hardwoods Mh 



Mature Douglas fir DF 



Sub-apine fir/limber pine SF 



Clearcuts nearby CC 



Lake nearby La 



Ftock outcrops nearby Fto 



Cave/Adit nearby Ca 



Riparian (willow, alder, aspen) Ri 



Beaver ponds nearby Be 



Sites were assigned codes determined by habitat oonponents at or near 

 that site, and bat occurrence and relative density (meastired by bat 

 passes recorded per hour of walking transect) using various habitats 

 was determined. 



Mixed hardwoods were primarily cottonwoods and/or aspen stands. 

 Mature Douglas fir stands consisted of trees generally 18 inches 

 diameter at breast height (DBH). "Nearby" habitat components were 

 within 1/4 mile (440 m) of the survey sites.
