or feeding," depending on activity, by species if identifiable, 

 and by time period. 



As information collected in 1991 suggested that little bat 

 activity occurred after midnight, walking transects were run no 

 later than that time. 



Habitats sampled for bat activity were broken into several 

 habitat components for analysis. These were : 



COMPONENT CODE 



Dense lodgepole pine forest Lpp 



Mixed hardwoods Mh 



Mature Douglas fir forest DF 



Sub-alpine fir/limber pine SF 



Clearcuts nearby CC

Rock outcrops nearby Ro 



Cave/Adit nearby Ca 



Riparian (willow, alder, aspen) Rl 



Beaver ponds nearby Bo 



Old buildings nearby BL 



Open areas (meadows, fields) Op 



Sites were assigned codes determined by habitat components at or 

 near that site, and bat occurrence and relative density (measured 

 by bat passes recorded per hour of walking transect) using
