Abstract
Abstract In south-central Idaho, fire-scar and tree regeneration patterns in the Salmon River Breaks portion of the Frank Church River of No Return Wilderness suggest that primarily surface fires occurred frequently in semiarid ponderosa pine (Pinus ponderosa var. ponderosa)/Douglas-fir (Pseudotsuga menziesii var. glauca) forests. Efficient fire suppression since about 1935 has markedly reduced area fire frequency and has altered fuel succession, contributing to recent crown fire behavior in north- and east-facing stands. Prescribed fires might now be difficult to contain in these communities, but burning would help return fuels to pre-1935 conditions. West. J. Appl. For. 3(3):76-80, July 1988.
