Notes: A Variable-Form Taper Function for Pinus Oocarpa Schiede in Central Honduras
A variable-form taper equation was developed for Pinus oocarpa Schiede in central Honduras. The model predicts tree profile as a function of total height, diameter at breast height, and relative height with a continuous function using a changing exponent to compensate for the form of different tree sections. The proposed five parameter model predicts underbark diameters with a standard error of 1.4 cm. The point where the taper curve changes from neiloid to paraboloid form, the inflection point, was assumed to occur at 25% of total height. For the data used, no changes in the predictive ability of the model were observed with different locations of the inflection point. For. Sci. 36(1):186-191.
