Loblolly Pine Growth and Yield Prediction for Managed West Gulf Plantations

摘要

A growth and yield prediction system is presented for use in thinned or unthinned loblolly pine plantations in the west gulf region. The equations predict cubic- and board-foot volume, green-weight, and dry-weight yields per unit area of wood only or wood with bark of entire tree boles, boles to any top diameter limit, and branches. Green and dry weight of foliage can also be predicted. Total stand yields for weight or volume are partitioned into 1-inch diameter classes to forecast stand and stock tables for all aboveground tree components for any stage of plantation development from ages 10 through 45. The data for the system of equations came from 859 measurements of thinned and unthinned long-term research study plots on cutover sites located in east Texas, Louisiana, and southern Mississippi.
