AN APPLICATION OF MATRIX MODELLING TO GROWTH PREDICTION IN SOLOMON ISLANDS RAIN FOREST

Abstract

A matrix projection model for Solomon Islands tropical rain forest was developed from a very restricted set of plot data collected on Kolombangara. Revisions were made to estimate ingrowth and mortality. The model was modified to provide predictions which approach climax forest in the Allardyce region. The model was used to develop predictions of growth rates in Allardyce forests. Limitations of the model and their effect on predictions are discussed. The predictions indicated that currently non-harvestable forest could be suitable for harvesting in 30 years, and that forest harvested with a high degree of care could be available for further harvesting in 40 years, provided that management practices are diligently conducted.
