Impacts on declining moose populations in southeastern Manitoba
Moose (Alces alces) populations in eastern and central North America have declined in many parts of their southern range. Many potential impacts on moose have been suggested as contributing to moose declines, including changing habitat disturbance regimes and enhanced disease transmission through in...

Many potential impacts on moose have been suggested as contributing to moose declines, including changing habitat disturbance regimes and enhanced disease transmission through increasing deer populations.

Moose were more likely to be found in areas with high logging (>25%) and recent forest fires (within the past 30 years), indicating that moose respond favorably to habitat disturbances. The presence of roads did not affect the likelihood of moose presence. Moose were negatively impacted by white-tailed deer (Odocoileus virginianus).

Among the variables considered, deer presence had the highest relative importance. This study suggests that to increase moose numbers, controlled burns and potential logging areas should be considered as ways to produce new habitat and plant growth for moose in the area.

Moose (Alces alces) populations in eastern and central North America have declined in many parts of their southern range. Many potential impacts on moose have been suggested as contributing to moose declines, including changing habitat disturbance regimes and enhanced disease transmission through increasing deer populations.
