Predicting Stand and Stock Tables from a Spacing Study in Naturally Regenerated Longleaf Pine

Abstract

A prediction system is presented whereby stand and stock tables are calculated for young natural longleaf pine stands of varying initial density. Tables can be output for stand conditions of 10 to 20 years of age, 300 to 1,500 initial trees per acre (at age lo), and 70 to 80 feet in site index (index age 50). The system also allows one to translate from density expressed as trees per acre at an age between 10 and 20 years to basal area at age 20 and thereby gain entry to another stand volume prediction and projection system for thinned natural longleaf pine that is operable for stand ages of 20 years and older.
