Prescribed Burning in Georgia's Piedmont Loblolly Pine Stands
Abstract:Summer prescribed fires were successful in killing back understory hardwoods and aiding the establishment of freegrowing loblolly pine seedlings in Georgia's lower Piedmont. No significant differences in the top-kill of hardwood stems were found between backfires and strip head fires; the kill from summer fires, however, was significantly greater than kill from winter fires. New regeneration following summer fires was twice as plentiful as on unburned tracts. Although results indicated no significant differences between burning techniques, strip head fires were less costly than backfires and generally less subject to wind fluctuations in hilly terrain. Wind speeds of at least 1 mile per hour within the stands were essential for proper fire movement. Optimum moisture condition for fine fuel was between 10 and 20 percent, with relative humidity from 25 to 50 percent. Soil erosion on these duff-mull sites was negligible. Generally, single repeat burns caused little additional kill of hardwood stems.
