Individual tree dbh increment and survival equations were developed for predicting annual dbh growth and annual probability of survival of loblolly pine trees in thinned and unthinned plantations on cutover, site-prepared lands. The dbh increment equation predicts dbh increment from a potential dbh growth function multiplied by a modifier function. The survival equations predicts the probability of survival as a function of crown ratio and the tree's competitive position in the stand. When used together, the equations should be useful to foresters interested in predicting future dbh and survival values for both thinned and unthinned stand conditions. South. J. Appl. For. 13(4):170-174.
