A Diameter-Class Matrix Model for Southeastern U.S. Coastal Plain Bottomland Hardwood Stands

Abstract

Matrix models for 5-year projections of natural bottomland hardwood stands in the Southeastern Coastal Plain are presented. The diameter distribution projection of species groups is based on diameter class, stand basal area, and trees per ac. The models were developed from data collected on 43 permanent 0.2 ac plots installed on six site types in the southeast. Predictions, based on 25 continuous forest inventory plots, show good agreement between the actual and projected diameter distributions. The models will be useful for short-term inventory projection and inclusion in forest management optimization routines. South. J. Appl. For. 14(4):189-195.

Modeling forest growth with management data: A matrix approach for the Italian Alps.

“…Like ingrowth, transition probabilities may also depend on stand state, and a common criticism of linear matrix models is that they assume a stationary upgrowth matrix (Harrison and Michie 1985). To avoid this, Solomon et al (1986), and Mengel and Roise (1990) made the matrix G a function of stand state. Buongiorno et al (1995) verified, for uneven-aged forests in the French Jura, the existence of an inverse relationship between transition probabilities and basal area.…”

Forest-level analyses of uneven-aged hardwood forests

“…For example, several single-tree and stand-level growth models have been developed to project the dynamics of unevenaged stands (Fries 1974;Peng 2000), and stand-level matrix growth models have been the most commonly used (e.g., Buongiorno and Michie 1980;Buongiorno et al 1994Buongiorno et al , 1995Mendoza et al 2000). Later studies (e.g., Solomon et al 1986;Mengel and Roise 1990) removed the assumption of constant parameters and allowed the residual growth and mortality to change with stand density. Buongiorno and Michie (1980) included ingrowth in this model, and it is commonly known as constant-parameter matrix model.…”
