Abstract

Vegetation-management practices allocate available resources and provide favorable conditions to promote the growth of desirable species. Animals, chemicals, fire, hand tools, and machinery are used to control interfering vegetation in established pine stands, improving survival, growth, and stand value. Following site preparation, herbaceous plants, shrubs, and vines may interfere with pine stand establishment and early growth to a greater extent than hardwood tree species, whereas hardwoods can most significantly affect pine growth later in the rotation, particularly after the fifth or sixth growing season. Weed community development is a function of the species composition of the previous stand and adjacent areas, environmental conditions, and the timing and intensity of disturbances such as mechanical or chemical site preparation and fire. The magnitude of pine growth response to weed control depends on the nature of interfering vegetation, stand age at treatment, site productivity, and treatment effectiveness. Removing weeds accelerates stand development, yielding more volume in less time. Increases in diameter growth, generally more responsive than height growth to weed control, may shift product classes to favor the more valuable sawtimber and veneer materials. Although nonchemical vegetation management (cultivation, mowing, grazing, and prescribed fire) can be effective, silvicultural herbicide technology is emphasized. Herbicide characteristics, application equipment, worker safety, and prescription of appropriate treatments are discussed relative to current technology for herbaceous plant control, pine release, and timber stand improvement. Understanding the biology of interfering vegetation, stand development, and limitations of weed-control practices should help managers implement effective vegetation managers implement effective vegetation management.
