Early detection and rapid response (EDRR) are primary activities of the
Oregon Department of Agriculture (ODA) Noxious Weed Control Program. Weeds
are listed and targeted for early detection and rapid response activities.
Program goals:
- Prevent introduction
-
Prevent widespread occurrence through
- Early detection efforts
- Implementation of control measures
ODA achieves prevention through the noxious weed quarantine and EDRR
projects. Program staff use a weed risk assessment process with the Oregon
State Weed Board (OSWB) to list species on the State Noxious Weed List.
Priority listed species, "A" (highest priority) and "T" (target) designated
weeds of limited distribution in the state, are the primary EDRR targets for
ODA.
-
Priority species are incorporated into presentations and outreach
activities to increase awareness.
-
Pest alerts and educational materials are distributed in an effort to find
new infestations.
- Survey for early detection is conducted.
-
Rapid response projects are implemented for eradication or containment.
-
Statewide management plans for “T” weeds are periodically updated to
clarify strategies and identify priority geographies.
ODA works with state and federal cooperators, county weed programs, county
weed management areas (CWMAs), and private landowners to implement EDRR
projects or provide assistance through OSWB grants.
Benefits of EDRR
-
34:1 benefit to cost ratio for EDRR projects, according to ODA's most
recent economic analysis,
-
Annual treatments for the control of “A” and “T” designated weeds reduce
the net acreage of many large infestations of weeds.
-
EDRR Successes in Oregon:
- Early detection efforts
- Kudzu, Pueraria lobata, 100% control
- Smooth cordgrass, 100% control
- Paterson's curse, Echium plantagineum, 99% control
- Giant hogweed, 99% control
