Abstract
Nothofagus pumilio is the species of largest geographical distribution and economical importance of Patagonia forests. There are few biometric related to the Patagonia forest management planning. Then, the aim of this work coas to construct individual growth models in diameter for different crown classes of medium quality site (IS60 = 9,8 m) N. pumilio forest in Santa Cruz Province (Argentina). The Chapman-Richards model showed good biological significance and statistics. Diameter growth had different behaviour according to the crown classes. The peak of the growth was at 62 and 52 years for the superior and inferior strata, being the maximal averages growth of 0.305 cm/year for dominant trees and of 0,12 cm/year for intermediate trees. The indirect validation of volumetric growth of the threw an error that varied between the 2.5 p. 100 and 20 p. 100Downloads
