Abstract:
In the summer of 1963, a number of measurement plots in natural stands of longleaf pine (Pinus palustris) were established across the southern United States with additional plots added regularly, resulting in 364 plots in this regional longleaf growth study (RLGS). Since plots were measured on successive occasions, the end result is 265848 records on individual trees from 1964 through 2011. These data include the variables necessary to examine the growth and yield of this species such as diameter at breast height, crown class, crown height, tree height, status of tree, age, and other additional measurements. Also included are weather data collected near these plots, soil horizon measurements, soil nutrient data, information on pole classification, as well as fallen needle data collected between 1992 and 1997. A shapefile containing these RLGS plot locations is also provided.
