Yield Prediction for Unthinned Natural Slash Pine Stands

Puntos clave

Total volume of unthinned slash pine stands can be predicted by diameter class using specific equations.
The Weibull distribution effectively models diameter frequency data, enabling accurate predictions.
Parameters for height and volume distributions can be calculated using stand age, site index, and current tree count.
These predictive models can assist in effective forest management strategies for slash pine.

Resumen

Abstract Equations are presented for predicting number of trees, mean height, and total volume outside bark by diameter class when stand age (A), site index (SI), and current number of trees per hectare (N) are known in unthinned natural stands of slash pine. The Weibull distribution was fitted to diameter frequency data, then suitable height-diameter and volume-D²H models were developed to calculate the Weibull parameters for the distributions of height and volume. Parameters for diameter and height distributions can be predicted from A, SI, and N and these equations are incorporated with the volume-D²H model in a computer program that generates a diameter frequency distribution, mean height, and total volume per acre or hectare by diameter class.
