Developing a merchantable volume equation for Pinus radiata D. Don in Galicia using a taper function
Keywords:

Abstract
Seventeen taper functions from six different groups of models (single polynomial, segmented polynomial, power, exponential, variable exponent and trigonometric taper fucntions) were fitted to diameter at different heights data from a sample of 280 trees of Pinus radiata D. Don in Galicia (Northwestern Spain). The equations obtained were compared to evaluate its performance and were validated using an independent sample of 85 trees to determine the best model. A total and merchantable volume equation was calculated by integration of the taper function. This equation is useful to estimate the yield of the stand for the different log qualities.Downloads
