Abstract

The yield-table projection method for modeling the development of regional timber inventories is outlined, and its application to softwood timber types in the Southern United States is described. Problems of simulating forest management practices and natural succession are discussed. A computer model that projects softwood timber inventories using yield-table projection and stand regeneration using a Markovian probability structure is presented. The methodology and projections of this model are compared with alternative approaches to predicting future timber inventories in this region.
