In 1987, tree content and tree taper functions for individual live standing planted loblolly and slash pine trees in East Texas were published 1. These equations were developed based on stem analyses of felled trees located adjacent to East Texas Pine Plantation Research Project (ETPPRP) permanent plots throughout East Texas. The 1987 report was based on 65 loblolly and 34 slash pine trees sampled during 1986. For both species, dbh (0) values ranged from about 2-12 inches and total height (H) values varied from about 10-60 feet.
