Conclusions (partial): Aerial track counts, trapper observations, harvest records, and carcass analysis indicated that furbearer populations in and near GAAR were in good condition and under no apparent threat of overharvest. Marten were harvested more than other species, but the population appeared to be healthy despite being at its northern habitat limit. Track counts showed the highest densities of red foxes, marten, lynx, and snowshoe hares were in areas having the greatest trapping pressure. Trapper observations of furbearer relative abundance in GAAR generally correlated with track counts. It was apparent from interviews with trappers that they were very aware of furbearer population changes and that they responded accordingly to prevent overharvest of any particular species. The current known distribution of trappers in and near GAAR seems to be compatible with the ability of populations to withstand the pressure. This situation is not likely to change significantly given the density of trappers, their conscientious efforts, and their access to suitable areas.
