Abstract: In this study we used data from 16 Appalachian hardwood stands, a growth and yield computer simulation model, and stump-to-mill logging cost-estimating software to evaluate the optimal economic timing of crop tree release (CTR) treatments. The simulated CTR treatments consisted of one-time logging operations at stand age 11, 23, 31, or 36 years, with the residual stands projected to their optimal economic rotation. The logging costs and revenues were estimated for the initial entry and for harvest at the optimal economic rotation. For comparison, the cost of CTR using hack-and-squirt herbicide treatments were computed as an alternative to the logging treatments at each age.
