About Alien Forest Pest Explorer

The Alien Forest Pest Explorer (AFPE) web tool

The Alien Forest Pest Explorer (AFPE) is an interactive web tool which provides detailed spatial data describing pest distributions and host inventory estimates for damaging, non-indigenous forest insect and disease pathogens currently established in the United States. To date, the AFPE database includes 74 species of forest insects and 15 species of forest pathogens. This tool allows users to scale county-level data to meet local forest health research needs.

While static maps displaying pest distributions are available here , the interactive mapping tool contains collective distribution information for 89 pests, in addition to host specific estimates derived from Forest Inventory and Analysis data, including volume, and rates of growth, removals and mortality, for 15 major pest species.

The AFPE database is maintained as a joint effort of Purdue University, the US Forest Service Northern Research Station, and the US Forest Service Forest Health Protection. As part of ongoing improvement and maintenance of this database, pest distribution data will be continually updated as data becomes available. Much of this information draws from field-reports made by Federal and State forest health specialists. Information on new pest finds is always welcome and we ask individuals who believe they have new data on pest distributions to contact Susan Crocker.
