Abstract

Some allometric functions with three predicting variables are presented, providing for the most common species of the Spanish managed forests the following items: stem volume, annual increment, bark percentage. The use of these functions of general scope, allows to replace measurements on, felled trees for the measurement on standing trees of the following predicting variables: b.h. diamete, total height, diameter at 4 m height, bark thickness, diameter increment of last 5 or 10 years. From these measurements, analytically, management tarif-tables can be obtained for the calculation of volume, increment, an bark.
