Slash burning in a clearcut under conditions producing very light to light burn intensities (<150°F or 66°C) for a short duration did stimulate resprouting, but resulted in almost no enrichment of biologically essential nutrients in the foliage. Burns of this low temperature range are not suitable for improving the quality and quantity of browse. Exceedingly dry soil conditions during the summer months appear to have resulted in low nutrient contents in clip plots where plants were crowded and dense, but not in controls where spacing was wider.
