Sulfur (S) content of samples of ponderosa pine (Pinus ponderosa Dougl. Ex Laws.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), Sitka alder (Alnus sinuata (Regel) Rydb.), snowbrush ceanothus (Ceanothus velutinus (Dougl.)), and forest litter combusted in an aerated muffle furnace at 375/sup 0/-575/sup 0/, 575/sup 0/-775/sup 0/, 775/sup 0/-975/sup 0/ and 975/sup 0/-1175/sup 0/C for 5, 30, and 60 min was compared with S content of unburned samples. Sulfur losses at 375/sup 0/-575/sup 0/C for 5 min ranged from 24 to 79% of S contained in unburned material. At 975/sup 0/-1175/sup 0/C for 60 min, losses ranged from 61 to 92%. Results suggest that prescribed burning and wildfire could potentially cause substantial volatilization losses of S from foliage and litter.
