Abstract:

Several mortality functions were examined to develop useful equations to predict early seedling survival of site-prepared loblolly pine plantations in the Georgia Piedmont region. Models were developed to predict surviving trees per acre at age 5 from stand initiation, as well as from age 1, under optimal planting and handling practices. The models performed reasonably, predicting surviving trees per acre at age 5 with an average absolute prediction error of 9.2% and 1.9% respectively. The age 1 to age 5 model was also found to perform reasonably on operational plantings with an average absolute prediction error of 3.3% for the study data. The models could be used to obtain starting densities for existing mortality models used in long term planning, or to predict the success of stand establishment after the first growing season. South.
