Abstract
Potential impact of litter removal in longleaf pine (Pinus palustris Mill.) plantations includes disruption of both hydrologic and macronutrient cycles. Both could cause growth reduction of plantation trees. In longleaf pine plantations on the Savannah River Plant which were examined 2 or 3 years following litter removal, growth (as determined by ring analysis) was reduced in the first year following removal. Growth reduction may also continue through the second year. Due to the rapid response to litter removal, disruption of the hydrologic cycle seems most probable. No differences were found in macronutrient concentration of foliage or litter components between treatments. The economic benefit of this practice must be evaluated in light of the observed growth reduction to determine the overall costs of this practice.
