Findley (1993) stated that an increase in species richness 

 accompanies increased availability of roosts. "Forested regions 

 lacking cliffs, caverns, and caves support fewer species, and 

 those that do occur are known to use trees as daytime roosts in 

 summer. Mountainous, broken topography with opportunities for 

 roosting in crevices, cliff faces, caverns, and caves support 

 richer communities" (Findley 1993). 



Management activities that encourage undisturbed stands of old- 

 growth forest, especially old stands of Douglas fir and mature 

 hardwoods, the maintenance of healthy riparian areas, including 

 snags and old individual aspens and cottonwoods, and the 

 preservation of caves and access to abandoned mine adits will 

 provide roosting and foraging habitat for a diversity and 

 abundance of bats. Management activities that encourage large 

 monocultures of relatively young trees, and even-aged management 

 of forest stands will be detrimental to the diversity and 

 abundance of bats using the forest.
