We studied short-term and long-term effects of aerial treatment of clearcuts with the herbicide glyphosate on moose (Alces aloes) habitat and activity in winter. For short-term (1-2 years posttreatment) studies, we measured browse availability, use and nutritional quality, winter cover, and moose activity on six treated and six untreated clearcuts. For longterm studies (7-11 years posttreatment), we sampled 14 clearcuts that had been treated 7-11 years earlier and five similarly aged untreated clearcuts. Moose appeared to prefer treated clearcuts 7-11 years after treatment because the dense conifer cover allowed foraging and bedding on the same site. We discuss management options for minimizing effects of glyphosate treatment on moose habitat.
