From l974-l98l, a study was conducted on the Kenai National Wildlife Refuge, Alaska to determine the response of spruce and moose forage [willow (Salix spp.), aspen (Populus tremuloides), and paper birch (Betula papyrifera) to fire and habitat management. Vegetation was sampled in five ages of burns, in stands which were managed from 1956-1971, and in stands managed by Le Tourneau tree crushers from 1974- 1978. Density of browse in burns that were 8, 13 and 30 years old was greater than in younger or older burns. In stands managed before 1974, browse density was greater than spruce by 1.8-12:1 and ranged Ibm 8680 to 34880 stems/ha. We sampled browse and spruce density before and four-years-after crushing in stands mattaged by LeTourneau tree crushers. Spruce density was reduced by 54-85% in the four areas managed. Density of browse increased significantly (p=>0.95) in two of the areas and decreased significantly in one. We further compared browse density in stands 8 to 30-years-old by soil phase on which they occurred. Greatest density of browse, especially willow, occurred on nearly level to rolling loamy soil. Greatest density of paper birch occurred on hilly to steep loamy soils. Aspen dominated stands occurring on moraines on gravelly soils; however, browse deosity was only 57% of that on the loamy soils. Density of browse on gravelly outwashes was about half that of the gravelly moraines indicating outwashes have low potential for management.
