✦ Synopsis
Application. In the southeastern United States, sapling hardwood-pine mixtures are often overstocked with trees and shrubs, which adversely affects development of individual trees. Treatments which reduce the total number of trees and shrubs increase the growth rate of remaining woody plants, and either prescribed burning or herbicides can be used for this purpose. However, sapling-sized stands are inherently dynamic. The present stand naturally shifted in composition from a hardwood-pine mixture, 54% hardwood tree and 46% loblolly pine basal area, to a loblolly pine-hardwood mixture, 38% hardwood tree and 62% loblolly pine basal area, between the 7th and 1 lth growing seasons after site preparation. Forest managers can use herbicides to accelerate a change in stand composition to pure pine. In the present stand, loblolly pine comprised over 80% of the total tree basal area on the chemically treated plots four years after application of hexazinone. Two dormant season prescribed bums did not significantly influence the natural shift in species composition.
