Abstract: In Manitoba, moose are the preferred prey species, and occupy similar landscapes to caribou. To reduce predation, caribou separate themselves from moose by selecting habitat less suitable to moose. Corridors linking caribou and moose habitat can facilitate access to caribou. The relationship between species and linear features was assessed through radio telemetry and surveys along natural and anthropogenic corridors. Surveys were used to determine distribution of all species relative to each other, and their proximity to linear features. Wolf scat was used to determine diet. Corridor surveys showed an even distribution of use between natural and anthropogenic corridors. Surveys showed association between moose and wolves, but not caribou. Wolves and moose were closer to river and road features and farther from lakes than caribou. Wolf diet included moose and beaver, not caribou. Caribou demonstrated partitioning from moose. Anthropogenic corridors appear to be additive, contributing to an overall wolf travel network.
