A survival model is needed in a forest growth system which predicts the survival of trees on individual basis or on a stand basis (Gertner, 1989). An individual-tree modeling approach is one of the better methods available for predicting growth and yield as it provides essential information about particular tree species; tree size, tree quality and tree present status. Individual tree survival models simulate survival and growth of individual trees in a forest stand. They are important in determining the development pattern of stand. A survival model is a major component of the Shortleaf Pine Stand Simulator (SLPSS) (Huebschmann, 1998) which has been developed for even-aged natural shortleaf pine forests. SLPSS includes a prediction equation for probability of tree survival which is based on repeatedly measured plots permanently located in the Ozark and Ouachita National forests which have diverse ages, site qualities and densities.
