Description: Sand pine is a very important species in Florida, producing significant quantities of fiber. The purpose of this study was to develop the site index and stand-level growth and yield equations managers need to make informed decisions. Data were collected from 35 seeded plots of Ocala sand pine covering a range of site indexes, ages, and densities in 1982-83. These plots were remeasured 5 and 10 years later and the data used to develop growth and yield equations by tree component. Equations for both current and future yields in volume and weight measures are given. These equations gave very good results when tested by comparing actual yields with predicted yields for a second set of 22 sand pine plantations measured in the panhandle area of Florida.
