The U.S. Forest Service's Laboratory at Pineville, LA has established and maintained over 250 permanent plots in longleaf pine plantations. This database represents a range of sites in south-central United States. Some of these plots represent over 50 years of stand development in plantations currently over 65 years old. All of the plots have recorded 20 years or more of stand development. These plots are being used to develop a model to predict the growth and development of longleaf plantations. This model will be a valuable tool for managers of longleaf plantations. In addition to these valuable, historic plots, the Pineville laboratory is currently establishing new permanent plots in young longleaf pine stands, representing operational plantations on a variety of sites.
