Fisher (Martes pennanti) harvest levels differ greatly between two adjacent regions in southcentral and southeastern Maine. The region of high harvests (approximately Wildlife Management Unity WMU 7) sustains an estimated population density of 1 fisher per 4.1 km2, compared to an estimated density of 1 per 65km2, in the low density region (WMUs 5 and 6). Prey abundance, as a casual factor, was examined between regions. Carcass condition and demographic parameters were also examined to delineate their relationship with fisher population levels.
