WINTER USE OF POWERLINE RIGHTS-OF-WAY BY MOOSE (ALCES ALCES)
The objectives of this study were to determine the influence of a powerline right-of-way on moose abundance and to characterize winter food availability and use by moose (Alces alces) in rights-of-way. Moose tracks and trails observed in six 120 km long by 500 m wide plots including a right-of-way w...

These means are not significantly different. The presence of rights-of-way did not seem to affect winter habitat selection or regional moose abundance. Results indicate that although rights-of-way studied were used by moose in winter, they did not offer very good feeding habitat, but neither did the adjacent forest habitat.
