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 8 radio tagged fisher in the West Chilcotin during the winter of 2006/07. 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 2008/09. The habitats used by the fisher during this winter season were similar to those used last year. Fishers in BC are known to be associated with riparian habitats and a large portion of fisher locations in this study were in riparian forest. Fishers seldom use habitats without continuous overhead cover and few 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. Generally, the fisher used mid to mature forests and the presence of spruce may also an important indicator of fisher habitat use. Other features used by fisher include the use of slash piles in harvested areas for subnivean denning. Fisher using the piles tended to access them using residual cover that had been left on the clearcut. 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, stands containing significant amounts of spruce, and retaining some slash piles in harvested areas. This retention is especially significant given the pace of salvage harvesting of mountain pine beetle infested stands in the Chilcotin.
