Abstract

Compilation, editing, and formatting of seven long-term longleaf pine (Pinus palustris Mill.) growth and yield studies has "been completed"and development of a growth and yield prediction system for longleaf pine plantations is underway. The studies are located in Central Louisiana, East Texas, Southern Mississippi, Southern Alabama, and Northern Florida Silvicultural treatments include variius planting and post-thinning densities, pruning, and fertilization. Residual basal area thinning treatments ranging from 40 to 140 ft2/acre (including unthinned control treatments) were applied as early as age 17 and repeated periodically for as many as 8 thinnings. Planting densities ranged from 250 to 2500 trees/acre. Stand ages within the database range from 4 to 63 years. Various growth and yield variables are compared in tables and graphs for the thinning and planting density treatments and locations. The results represent some of the growth and yield trends that will be modeled in detail to develop a comprehensive prediction system for this important species of the southern United States.
