WINTER UTILIZATION BY MOOSE OF GLYPHOSATE-TREATED CUTOVERS
Glyphosate (N-(phosphonomethyl) glycine) is an important silvicultural tool used in the boreal forest. This study was undertaken to determine if the use of this herbicide for controlling competing shrubs in plantations is significantly reducing forage resources and subsequent overwinter utilization...

Glyphosate (N-(phosphonomethyl) glycine) is an important silvicultural tool used in the boreal forest.
