Yield Prediction for Mechanically Site-Prepared Slash Pine Plantations in the Southeastern Coastal Plain

Abstract

Abstract Yield prediction equations with different input requirements, and intended for stand-level management planning, are presented in four separate sections: (1) Unthinned plantations with site index and planting survival at age 2 as input. Per-acre basal area and volume prediction equations are presented. (2) Thinned or unthinned plantations with age, surviving trees per acre, and average dominant/codominant height or site index as input; (3) A Weibull distribution-based yield prediction system for existing unthinned plantations with age, surviving trees per acre, and average dominant/codominant height as input. Tree volume and height prediction equations, developed for this plantation resource, are presented. (4) Future yield for thinned and unthinned plantations when an initial stand table is available. Survival and per-acre basal area projection equations of Section 2 are required to project the stand table. South. J. Appl. For. 17(4):163-173.
