6) Large trees with natural cavities should not be removed. Besides providing nesting and 

 roosting sites for birds, some bats will use them for the same purposes (see Gellman and Zielinski 

 1996, Mattson et al. 1996, Wunder and Carey 1996). 



7) Because bats are vagile, some species may go undetected unless routine and long-term 

 monitoring is conducted. Such a program would be unprecedented in Montana and could 

 potentially provide a wealth of information on bat biology currently unavailable for this region.
