    Encouraged by the high quality and marketability of longleaf pine (Pinus palustris Mill.), many landowners are taking advantage of recent improvements in longleaf regeneration techniques (Mann 1969, 197O; Croker and Boyer 1975; Farrar and White 1983; Dennington and Farrar 1983) and are growing longleaf pine today. Successful longleaf timber management demands predictable growth and yield resulting from various management alternatives. Guidance exists in yield tables for unthinned naturally, regenerated stands (Schumacher and Coile 1960, Forest Service 1976) and for unthinned plantations (Lohrey and Bailey 1977). Lohrey (1976) also provides information on thinned plantations. Research Paper SO-156 (Farrar 1979) described growth and yield predictions for a comprehensive array of stand ages, site qualities, and residual densities maintained by periodic thinning in natural stands. Research was based on the first 5-year growth in a regional natural longleaf pine growth study. This paper updates SO-156 and describes a more versatile system for stand volume and volume growth prediction. Data from the first and second 5-year growth periods allow estimates of total and merchantable stand volume in cubic feet, cords, dry weight, and board feet (tbm).
