Selection Management in Southern Appalachian Hardwoods

Abstract

Abstract A woodland tract of southern Appalachian cove hardwoods and mixed oak has been managed under the selection system of silviculture since 1946. Simply cutting in all commercial diameter classes (i.e., 6.0 inches and larger), as was the practice during the first 24 years, failed to develop enough desirable saplings and poles to maintain the system. After 1970, herbicide treatment of undesirable, tolerant understory species in openings created by removal of large trees or groups of trees has improved the status of desirable saplings. Although long-term costs of management and yields are uncertain, the study suggests that creation of larger openings and treatment of undesirable understory species offers at least a chance for success with the selection system in southern Appalachian hardwoods.
