In 1949, a loblolly pine growing space study was established on the Hitchiti Experimental Forest in Georgia as a planned part of a regional growing space study. It is unknown if the rest of the locations were ever established. The study on the Hitchiti was established in even-aged loblolly pine stands of many age classes and densities. This study involved measurements for 72 plots taken roughly every five years by the original research organization through 1983 and then by the current author's unit in 1993 and 2002. Data include plot level information such as location, soil type, stand density as well and basal area both before and after thinning. Measurements throughout the duration of the study have varied across the years, but include tree level information such as species, location, diameter at breast height, tree height, height to base of live crown, crown class, and height of the tree to a 4- or 8-inch top. However, in the early years only expected crop trees were assigned numbers so individual tree growth can only be charted by matching trees based on tally order and diameter. The study was established to study the relationship between growing space and yield as a function of three variables: age, site, and growing space.
