Simultaneous total and merchantable volume equations and a compatible taper function for loblolly pine

, : Simultaneous total and merchantable volume equations and a compatible taper function for loblolly pine. Canadian Journal of Forest Research 17(1): 87-92

Loblolly pine (Pinus taeda L.) is an important source of raw material for the forest products industry of Santa Catarina, Brazil. Data from 159 trees were used to develop a simultaneously estiamted total and merchantable volume equation, which treats total volume as a special case merchantable volume with Dm, the diameter limit, equal to zero. By imposing a restriction on the parameters of the total and merchantable volume equation, a compatible taper function was derived that predicts diameter at breast height when merchantable height equals 1.3 m. The taper function possesses an analytic point of inflection in the lower portion of the stem.
