Abstract

In 1979 the technique of modeling diameter distributions by probabilistic functions was first applied for Hyink & Moser in forecasting growth and production of uneven aged and heterogeneous forests. However, today few studies use this method for planning the production in these forests for not knowing the operational feasibility of the technique. Therefore this paper presents a review of the characteristics that allow the modeling of growth and yield by diameter class, highlighting the importance of the dynamics of recruitment, mortality, survival, and population of attributes related to the modeling of Weibull distribution, with the specific statistics used in the modeling of yield by this method.
