When G. A. Pearson arrived at Fort Valley to establish the first Forest Service Experiment Station he found many open park-like stands similar to those in Figure 1. Within two years, Pearson had outlined the major factors detrimental to the establishment of ponderosa pine seedlings (Pearson 1910). During the next almost 40 years, he wrote many articles on methods of cutting, tree planting, thinning, raising seedlings, natural regeneration and other aspects of forest management. His findings are contained in his landmark treatise, "Management of Ponderosa Pine in the Southwest" (1950). Gaines and Shaw (1958) summarize the first fifty years of research at Fort Valley. The following reviews Pearson's findings along with discoveries made since 1958.
