Abstract

Aerial application of glyphosate at 1.07 kg/ha on a conifer plantation released planted trees satisfactorily while reducing browse stems available to moose (Alces alces) by only 5-41%. Loss of biomass for 8 major browse species (90% of stems browed) amounted to 96 kg/ha. Browsed stems/ha decreased from 15-82% on 5 of 6 sprayed strata, and increased by 130-3200 % in 5 of 6 control strata, BUT variability rendered difference is insignificant. On a second study area, ground application of glyphosate at 2.7 kg/ha are pre-planting site preparation reduced available browse by 63-92%, resulting in a loss of 145 kg/ha (for 90% of the browsed stems). Apparently, some silvicultural objectives can be achieved while retaining substantial densities of browse plants for at least the first year, but other silvicultural applications may reduce browse availability more seriously.
