Invasive Plants – Early Detection and Rapid Response

The most cost-efficient way to manage invasive plants is to monitor and treat new threats before they have time to become established. As a result, DPR has developed an Early Detection, Rapid Response (EDRR) Program for Arlington County. This program provides a framework for managing new threats as they arise. DPR has identified several species that have been found to be very invasive in other areas, but are not yet widespread in Arlington. DPR staff will be monitoring Arlington parks for EDRR species on a routine basis.

How You Can Help

Volunteers can get involved by learning identification techniques for EDRR species. Check out the information below, created by the DC Invader Detectives. Volunteers can help with surveying and mapping these problem species in parks throughout the county. Contact the Natural Resources Management Unit at for more information.
