Oak sawlog and pulpwood losses in stands defoliated by gypsy moths have become a critical problem for some forest landowners. The salvage of gypsy moth-killed hardwoods can become an important source of pulpwood and sawlogs. This study documents a methodology and provides guidelines to determine defoliated oak stands that are economically salvageable. Stand data from 574 defoliated oak stands were integrated with stump-to-mill logging costs and wood values. Cable and ground-based logging costs were integrated with three levels of sawlog and pulpwood-fuelwood prices to determine if salvage would be economical. The data and methodology were used to develop feasibility matrices for red, white, chestnut, scarlet, and black oak. The results show that the most profitable salvage operations will be those in stands with high volumes, a valuable species mix, a large component of grade logs on gentle ground, which are salvageable by ground-based systems, and are close to the mill. Managers, planners, landowners, and loggers can use these matrices to determine which stands are profitable.
