and Jones, 1989) . Four-eared Bat Cave should be thoroughly 

 searched for sign of use by bats, especially use by Plecotus 

 townsendii . It should be visited during the winter and in early 

 spring, since this summer's investigation suggests that it may 

 not be used as a summer roost. Syke's Cave should be located and 

 searched for bat sign, and Royce Cave should be searched more 

 thoroughly and netting should be done at its entrance. The 

 several mining tunnels located should be investigated more 

 thoroughly. More complete data from all caves and mining tunnels 

 needs to be collected including humidity readings and temperature 

 readings at various locations within the caves taken throughout 

 the season. A more complete vegetation survey conducted at each 

 site, as well as more information collected on slope and aspect 

 of the cave and tunnel entrances will be necessary to 

 characterize the cave structures and habitat.
