Identifying Intensively Managed Pine Plantation Acreage in the South

Long-term timber supply projections are a function of many factors including the intensively managed southern pine plantation area. A survey of southern forestry herbicide distributors was developed to determine the acreage of southern pine plantations that included herbicide applications in the management regime. Survey techniques are discussed and herbicide-treated pine plantation acres are reported by subregion, type of sale (turnkey or direct), and type of treatment (site preparation, pine release, or herbaceous weed control) for 2001 and 2002. The survey methodology produced technically acceptable results; however, the marketing and competitive aspects of the data proved to limit survey participation. A usable survey method is described with a potential for future timber supply modeling application. South. J. Appl. For. 29(3):163–166.
