We began bat studies in 1996 to inventory bat species in Clayoquot Sound and identify their critical habitat requirements. We used mistnetting to confirm the presence of six species of bats. We located two roost sites. We suggest that forest structure affects the flying and foraging activities of bats as dense stands and dense foliage reduces bat flight maneuverability. This document concludes by making the following recommendations for future samplings: that to increase the sample sizes in all locations, ensure that after each visit to an area, at least one sampling night is completed before moving on to another location, that to determine more information about critical structures for roosting, we need to intensify our efforts to radio-track bats to roost sites, and that since more bat passes were recorded at riparian areas relative to forested sites, we need to determine adequate buffer zones for riparian feeding areas.
