AbstractThis study was designed to evaluate the effect of clearcutting on moose (Alces alces americana) populations in northcentral Newfoundland. Fourteen logged areas of various size and age were sampled for potential standing forage and current use. Balsam fir (Abies balsamea), white birch (Betula papyrifera), pin-cherry (Prunus pensylvanica), and willow (Salix spp.) were the most common forage species. Moose browsed most heavily upon pin-cherry, followed by birch and willow. Balsam fir was only lightly used. The most efficient sized plot for measuring browse production was found to be 6 m2. Available browse on balsam fir trees ≤5 m in height was measured by linear correlation with the product of stem diameter and height. Most winter browse was in cuts 8 to 10 years of age. The greatest use was in cuts 40 to 50 ha in size. A forest management plan which encourages a heterogeneous pattern of 40 to 50 ha block cuts and mature forest cover is suggested to be most compatible with the management of moose in northcentral Newfoundland.
