Invasive Pest Risk Maps: European Gypsy Moth - Lymantria dispar dispar

These risk maps for economically and ecologically important invasive species provide land managers with information to assess the potential for species introduction, establishment, and landscape susceptibility.

The European gypsy moth (EGM), Lymantria dispar dispar, is one of North America's most destructive invasive forest pests. It was accidentally introduced into the United States near Boston, MA in the late 1890s. Since its introduction, EGM has expanded its range to encompass the mid-Atlantic and Northeastern States, as well as Counties in Ohio, Michigan, Indiana, Illinois, and Wisconsin. Because EGM introductions have been detected in western states including CA, OR, UT, and WA, considerable efforts are made each year at the state and federal levels to detect new infestations, eradicate isolated populations, and limit the spread of EGM beyond the known infested area.

The EGM risk assessment provides an objective, science based approach to quantifying the risk of EGM introduction, establishment, and susceptibility. The goal of the project is to: 1) improve the effectiveness of the EGM survey, 2) increase timeliness of detections outside the known infested area, and 3) identify places that require further monitoring. The following EGM risk assessment products were developed by the USDA Forest Service, Forest Health Assessment and Applied Sciences Team in co-operation with the Animal and Plant Health Inspection Service, Plant Protection and Quarantine, and the U.S. Geological Survey staff members, to address the needs of EGM Program Managers at both the State and Federal levels.

Intended Use
These risk maps for economically and ecologically important invasive species provide land managers with information to assess the potential for species introduction, establishment, and landscape susceptibility; to develop a detection strategy for *Anoplophora glabripennis* that focuses efforts in areas where there is susceptible maple host species which occur in forested habitat.
