Species OCmposition, Tree QUality and wood properties of Southern pine Stands Under Ecosystem Management on National FOrests in the Piendmont and COastal Plan

摘要

National Forests in the United states are under sustainable ecosystem management to conserve biodivesity, achieve sustainable ocnditins and improve the balance among forest values. This paper reports on a study established to identify the implications of ecosystem management strategies on natural stands in the piedmont and Coastal Plain. the impact of partial havests, group selctions, seed tree cuts and no human disturbance on species composition, wood properties and tree quality of pine stands in the piedmont and coastal Plain is described.
