“…Habitat fragmentation isolates habitat patches and reduces patch size, thereby increasing the vulnerability of local popu¬ lations to environmental and demographic threats (Shaffer, 1981;Lande, 1988). Boreal caribou are wide-ranging with natural occurrence at low popula¬ tion densities typically between 0.03 -0.05 caribou/ km2, and have protracted time lag responses to habitat changes (Tilman et al, 1994;Arsenault, 2003;Schaeffer, 2003;Environment Canada, 2007;Vors et al, 2007;Wilkinson, 2008). Therefore, studies that focus on landscape pattern analysis, as well as struc¬ tural and functional habitat connectivity, are neces¬ sary to determine impact development thresholds, critical habitat, and movement corridors (Manseau et al, 2002;O'Brien et al, 2006;Fall et al, 2007;Racey & Arsenault, 2007;Galpern et al, 2010).…”
