Invasive Species... A Growing Problem...

In recent years, there has been a growing awareness that introduced invasive species are having serious impacts on the U.S. economy and natural ecosystems. According to recent estimates, control costs and losses due to invasive species now exceed $150 billion per year. About $50 billion of this total is due to invasive plants.

EDRR... Where does it fit?

EDRR is one of many strategies that are used to address the invasive species problem. These include:

  • Prevention (production of pest free commodities)
  • Preclearance (inspection of commodities at foreign ports of export)
  • Exclusion (inspection of imported commodities at U.S. Ports of Entry)
  • Early Detection and Rapid Response
  • Long Term Control (population reduction)

The National EDRR System - How it began...

FICMNEW National EDRR Planning Workshop. Ft. Collins, CO. June, 2000

In 1998, the U.S. Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) adopted the development of a National Early Detection and Rapid Response System for Invasive Plants as one of its long term goals. FICMNEW hosted the first National EDRR Planning Workshop in Ft. Collins, Colorado, in 2000.

Since that time, the U.S. Geological Survey Biological Resources Discipline has been working with numerous agencies and partner groups throughout the U.S. and Canada to develop the various elements and processes of the system that are showcased on this website.






The National EDRR Tool Box – What it does...

The main purpose of the EDRR Tool Box is to promote EDRR as the preferred management strategy for new invasive species, by:

  • Providing Weeds Alerts for new species in the USA and Canada
  • Encouraging interagency cooperation
  • Showcasing the agency programs and task Forces
  • Training Volunteers to detect and report strange new species
  • Providing links to EDRR Resources and Expertise
