Garant, Crete Yves, Michel Fisher, Martes pennanti, home range characteristics in a high density untrapped population in southern Quebec. 1997 The Canadian Field-Naturalist 111(3):359-364 Most Fisher (Martes pennanti) populations in North America are moderately to heavily trapped. Trapping may reduce density and can indirectly affect spacing patterns of solitary terrestrial carnivores by creating vacant territories. From 1991-1993, we studied home ranges of radio-collared fishers in Gatineau Park (Quebec) where trapping had been prohibited for > 20 years. p.359
Trapping affects more than population size; it has repercussions on other population attributes (e.g., age structure, sex ratio) that we should consider for sound management of this furbearer. p, 363
