Fuels consumption and nitrogen loss following prescribed fire: a comparison of prescription types in the Southern appalachians


Prescribed burning is frequently used as a tool for restoration of plant communities, wildlife habitat improvement, and site preparation. We compared and contrasted the effects of four burning prescriptions on forest floor and fine fuels consumption, and nitrogen loss. The burning treatments included dry (DU) and mesic (MU) understory burns, stand replacement (SR) burning, and fell and burn (FB) site preparation. On all sites, forest floor was sampled before and immediately after burning. It was separated into woody fuels ( -1 (90 percent wood, 10 percent litter, -1 (5 percent wood, 55 percent litter, 40 percent humus) on the MU burns. Nitrogen losses followed similar patterns 292 kg ha-1 (70 percent from wood, 28 percent litter, -1 (65 percent from wood, 35 percent litter, < 5 percent humus) on the SR site. High-intensity ground fires may result in greater losses of site nutrients, and this may have negative short- and long-term consequences.
