Abstract
Oak–pine stands in the Upper Piedmont of Georgia were whole-tree harvested to 10-cm and 2.5-cm lower dbh limits in both the dormant and early growing seasons. Pine natural regeneration and hardwood coppice were observed through five growing seasons. Dormant-season harvesting resulted in pine stocking of over 90% and 60% for the 2.5-cm and 10-cm limit, respectively. Growing-season harvesting resulted in initial pine stocking of less than 15%. Initial coppice coverage was greatest after dormant-season harvesting, but due to pine competition was approximately equal to the growing-season harvest coverage after 5 years. Residual stems with total basal areas less than 7 m2/ha after 10-cm limit cutting suppressed growth of both the pine regeneration and the hardwood coppice. Results demonstrate that modifications in harvesting alone can substantially influence subsequent species composition and stand development.
