Abstract
The Duke Forest FACE experiment was set up to investigate the impact of elevated CO2 levels on a larger eco system. One of the studies dealt with the impact of elevated CO2 levels on the onset and cessation of growth of loblolly pine trees (Pinus taeda L.). In this study the times of these events were determined for each year, 1996 - 2002. The rate of growth, the growth duration, and actual growth were determined from the models of onset and cessation of growth. Adjusted for initial basal area, the rate of growth, the actual growth, and the current basal area were slightly greater for elevated CO2 levels. There was no difference between the two CO2 levels for any of the time variables, onset, cessation, and growth period.
