An examination of the absence of established moose (Alces alces) populations
ABSTRACT: An analysis was performed on habitat-related factors for the southeastern side of Cape Breton Island, Nova Scotia to investigate the continued absence of moose (Alces alces) from the region. Temperature and snow depth, at times, reach levels that could cause thermal stress or impede moveme...

Anthropogenic factors such as poaching were not considered influential enough to exclude moose. A forest habitat comparison analysis was performed to identify habitat features that were statistically correlated with moose presence, and then were applied in a probability model to predict moose presence in the study area. The logistic regression model used to predict the probability of moose presence was composed of positively associated forest inventory variables (softwood average maturity, hardwood average maturity, % mixed hardwood, % non-forested area, total wetland area) that best fit the data.
