Early Detection and Rapid Response (EDRR)

Preventing the introduction of invasive weeds is the first line of defense against new invasions.

“To protect Oregon from invasive species, it is important to stop new outbreaks before they start. By the time an invader is easily noticeable and begins to cause damage, it is often too late. It can be difficult and expensive to remove an established invader. However, by detecting new outbreaks early and acting quickly to control them, we can avoid many of the environmental and economic losses caused by invasive species.” 

EDRR focuses on prioritizing the limited resources available to best manage the huge impact that invasive weeds have on Yamhill County. Detecting invasive weeds when they first arrive into the county, while populations are still controllable, is the first step of EDRR.  Then those weed populations will be rapidly controlled at the appropriate time.

Yamhill SWCD EDRR Program

The Yamhill Soil & Water Conservation District (district) has developed an EDRR Program to detect and eradicate new invasive plants in Yamhill County before they get out of control. There is a list of six weed species that we wish to keep out of Yamhill County, or confine to the locations where they have already established. This list of species is known as the “EDRR (weed) List”.
Whenever these species are seen or reported in the county, and after gaining permission from landowners, we are committed to deploy a control team to the reported location as quickly as possible in an effort to eradicate or control spreading.
