Site index description

We use the site index developed by the Forest Research Institute in Chile. The index was obtained from extensive and intensive forest inventory were basic data from height and age were measured in different geographic areas. The geographical areas were stratified considering homogeneous soil and climatic areas to avoid distortions on estimators due different age distributions. The empirical equations for the site index were fitted base on a regression model (height and age variables) for the species (García 1970; Schlatter and Gerding 1995; Pinilla S. 1998; INFOR 1999). The equation obtain for the index curves were:

,

Where A is the mean height of dominant and codominant trees and E is the age, for Pinus radiata and

H=75.3 (l-e-bt)1/0.863

Where H is the height dominant in meters T is the age in years, b depend of the site quality, for Eucalyptus sp. (Garcia 1995).
