Woody fuel dimensions within Great Smoky Mountains National Park. Research/resources management report

Diameters and bulk density were examined for downed wood in major forest types found in Great Smoky Mountains National Park. One-hour fuel (0 - 7 mm) diameters were smallest in spruce-fir and hemlock forests, intermediate in yellow pine forests, and largest in hardwood forests. Diameters for 10 hour (7 - 25 mm) and 100 hour (25 - 76 mm) fuels were not significantly different between forest types. Bulk density decreased with a decrease in bark coverage.
