Early Detection & Distribution Mapping System (EDDMapS)
University of Georgia. Center for Invasive Species and Ecosystem Health.
Early Detection and Distribution Mapping System (EDDMapS), provides a more accurate picture of the distribution of invasive species. EDDMapS will allow land managers, agencies and others to set priorities for early detection and rapid response (EDRR), as well as formulate overall invasive plant management action plans. Includes distribution data by species and by county.
First Detector Program

National Plant Diagnostic Network.

First Detector, a program of the National Plant Diagnostic Network (NPDN), equips a nationwide network of individuals to rapidly detect and report the presence of invasive, exotic plant pathogens, arthropods, nematodes, and weeds. If you suspect the presence of a high-impact plant pest or pathogen, contact a diagnostician and submit a sample for diagnosis.

iMapInvasives - Invasive Species Identification Guides

Nature Conservancy. iMapInvasives.

Includes a variety of published guides and internet resources (videos) for use in identifying invasive species that are found in the participating states, provinces, and regions of the iMapInvasives network. The iMapInvasives network is currently comprised of various U.S. states and one Canadian province (Arizona, Florida, Kentucky, Maine, New York, Oregon, Pennsylvania, Vermont, Virginia, and West Virginia, and in Canada - Saskatchewan).

Invasive Species Experts Database

National Plant Diagnostic Network (NPDN)

National Plant Diagnostic Network.

NPDN is a national network of diagnostic laboratories that rapidly and accurately detect and report pathogens that cause plant diseases of national interest, particularly those that could be deemed to be a biosecurity risk. The specific purpose of the NPDN is to provide a cohesive, distributed system to quickly detect and identify pests and pathogens of concern.
