This is an interim report in a long-term study on fisher ecology and the results must be viewed with caution. This portion of the study involved monitoring 4 radio tagged female fisher in the West Chilcotin during the maternal season (May July 2006). No measurement on the availability of habitat features has yet been completed. All field work is expected to be complete by 2007 with final reports completed in 2008. The habitats used by the fisher during the maternal season were similar to those used during the winter season. Fishers in BC are known to be associated with riparian habitats and the majority of fisher locations in this study were in riparian forest. Fishers seldom use habitats without continuous overhead cover and only 3% of the locations in this study were in non-forested areas. Fishers are also thought to prefer older forest due to the presence of structures such as snags and large diameter coarse woody debris. Most observations in this study were in older structural stage forest stands. Mixed tree species stands, especially those containing white spruce, were also used extensively. Given the agreement between the findings here and what is known about fisher ecology elsewhere, interim forest management recommendations are for the maintenances of riparian habitats and mixed tree species stands. This retention is especially significant given the pace of salvage harvesting of mountain pine beetle infested stands in the Chilcotin.
