Early Detection and Rapid Response

Describes detection methods for invasive plant species and coordinated responses to these threats. See Manager's Tool Kit - Early Detection and Rapid Response for general resources and other species.

WSSA Scientists Stress the Importance of Early Response to Invasive Weeds (Mar 26, 2013)
Weed Science Society of America.
"Early detection creates opportunities for us to make smart decisions and eradicate new invasive weeds before they spread widely and become entrenched. In those early stages, control efforts are typically easier, more successful and far more cost effective."

Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) National EDRR Plan for Invasive Plants

Background: Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW), is leading a national effort to develop and implement a National Early Detection and Rapid Response System for Invasive Plants in the United States. The primary long term goals of the proposed system are to detect, report, and identify suspected new plants with free living populations in the United States.

  • Phase I - Outreach and Education
  • Phase II - Pilot Projects: With New England (with the Invasive Plant Atlas of New England), the Mid-South (Mississippi State University), North Carolina, South Carolina, Nebraska, Wyoming, Colorado, and Hawaii

Early Detection & Distribution Mapping System (EDDMapS)
University of Georgia. Center for Invasive Species and Ecosystem Health.
Provides distribution data at the State and County level and point locations. See the section Who's Using It? for mapping distribution in various areas of the country. Includes:

Early Detection & Distribution Mapping System (EDDMapS) - Alaska
Provides distribution data and abundance of exotic and invasive plant species in Alaska.

Early Detection & Distribution Mapping System (EDDMapS) - Mid-Atlantic Early Detection Network (MAEDN)
MAEDN is a vast network of land managers, field experts, citizen scientists, naturalists, gardeners and others interested in documenting invasive plant occurrences in the mid-Atlantic region for the purposes of early detection, improved management and better coordination. The region includes Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia.
