A Matrix Model of Uneven-Aged Forest Management

Abstract

A matrix model of a selection forest was developed. Parameters of the model represent (i) stochastic transition of trees between diameter classes and (ii) ingrowth of new trees, which depends upon the condition of the stand. Parameters were estimated from North-Central region hardwoods data. The model was used to predict long-term growth of undisturbed and managed stands. A linear programming method was used to determine sustained-yield management regimes which would maximize the net present value of periodic harvests. The method allowed for the joint determination of optimum harvest, residual stock, diameter distribution, and cutting cycle. Forest Sci. 26:609-625.
