A matrix growth model of the Swedish forest

Ola Sallnäs

Open full text 59 citations

Abstract

An area forest matrix model was developed, intended for use as a tool for modelling forest yield in an integrated forest sector model. The model was estimated from data from the Swedish National Forest Survey. Log-linear models are used in the estimation of transition probabilities. By comparison with another growth model, the matrix model generates reasonable growth levels and growth patterns. General characteristics of the model and the matrix concept are analyzed and discussed. In general the model is considered suitable for implementation in integrated forest sector modelling.
