Abstract

Data from permanent remeasurement plots established in loblolly pine (Pinus taeda L.) plantations growing in the Misiones/Paraná region of South America were used to develop and test a system of equations for predicting and projecting volume yields for thinned and unthinned stands in that region. Component equations parameterized with the data included dominant height/site index, basal area prediction and projection, survival, and total volume yield prediction. Improved estimates of yield were achieved when geographic coordinates were included in the basal area and total volume yield equation. Yield projections suggest that the system as a whole can be a useful tool for modeling growth and yield in this region of South America.
