Abstract: Bat use of the Weymer Creek karst area, Vancouver Island, British Columbia, Canada, was studied from 1996 to 1998, following the discovery of a Myotis bat hibernaculum. We used a variety of monitoring techniques backed up by careful observations to develop an understanding of how bats use the study area and to determine the climatic characteristics of subsurface bat habitat. We hope to produce recommendations that will lead to sound management of Myotis bats and their habitat within the west coast rain forest karst environment. The Weymer caves are used for swarming and hibernation by Myotis volans, M. lucifugus, M. yumanensis, and the rare and endangered M. keenii. In addition, M. californicus and Eptesicus fuscus use the surface habitat for feeding. Caves used for swarming and hibernation vary in elevation from 500 to 900 m, with the largest concentrations of hibernating bats being found above 800 m. Most hibernating bats are found in deep passages with stable environments of 34C and...
