Abstract
Total outside and inside bark cubic foot volume equations are presented for southwestern ponderosa pine (Pinus ponderosa) that are functions of total tree height, diameter breast height, and Girard form class. These equations are appropriate for trees of any size or age, and no distinction is made between "blackjack" and "yellow pine" trees. Equations are included to predict merchantable volume to any upper stem diameter or merchantable height. Taper and merchantable height functions are indirectly derived from the merchantable volume equations. West. J. Appl For. 3(4):123-125, October 1988.
