Abstract
Age-8 and -9 data from the 13 study plantations of the Competition Omission Monitoring Project (COMP) were used to project yields and derive economic outcomes for loblolly pine (Pinus taeda L.). COMP &eatments were chop-bum, complete woody plant control, complete herbaceous plant control for 4 years, and complete woody and herbaceous (W+)I) control. Yields projected with the NCSU Managed Pine Plantation Simulator were greatest for W+H control followed by woody control. Rankings for the other two treatments depended on site index. Profitability increased as site index increased and discount rate and hardwood densities decreased. Woody control was the most profitable on productive sites at discount rates below 5 percent.
