Abstract

The gypsy moth, Lymantria dispar (L.), a major defoliator of eastern hardwood forests, has become established in Virginia and is moving towards Tennessee. In preparation for its inevitable arrival, Tennessee’s timberlands are hazard rated to identify those areas most susceptible to gypsy moth defoliation. Tree, stand, and site characteristics associated with gypsy moth defoliation are used to identify USDA Forest Service, Southern Forest Inventory and Analysis, survey plots with a high hazard to gypsy moth defoliation. One-quarter of the State’s timberland, containing 30 percent of the State’s hardwood inventory, is classified as high hazard. These highhazard acres are unevenly distributed across the State and can change over time. Hazard rating provides useful information in planning gypsy moth detection, monitoring, and prevention activities.
