Certain caves in the Upper Snake River Districts serve as critical winter habitat
for bats because they provide a narrow yet optimum range of temperature and other
microclimatical variables required for successful hibernation. Research has
indicated that all bat species are extremely susceptible and sensitive to human
disturbance during hibernation, and that recreational caving trips during the
hibernation season are detrimental to the survival of bat species.

Dated: December 19, 1997.
