Description: Regeneration was studied on a mixed conifer stand on granitic soils on the Klamath National Forest. Six years after logging and hand planting with Douglas-fir, stocking and growth on cutblocks where slash had been broadcast burned was compared with that on similar unburned cutblocks. Conifers were seven times more plentiful on the unburned areas, the average height of the tallest conifer on each plot was nearly twice as great, and the yearly height growth was 27 percent greater. Results suggest that modification of burning policies on this soil type may improve regeneration.
