Control & Management


It is necessary to contain, control, and manage invasive species, once established in Oregon, for long-term protection of our resources. Our strategies include containment, management along pathways in and out of affected areas, increasing funding and resources dedicated to our long-term protection of resources, identification of new eradication methods, and integration of a systems approach to ensure ecosystem recovery and resilience. 


See greater details of these strategies in the Statewide Action Plan

  1. Control spread of Invasive species once established in Oregon focusing on pathways into and out of affected areas.

  2. Identify and secure sufficient funding for effective invasive species control.

  3. Evaluate existing control methods, prioritize efforts, and identify new techniques for greater control and efficacy of management.

  4. Ensure ecosystem recovery processes are an essential component of control and management treatments to restore resilience in the system and reduce need for ongoing management.

Situation: Japanese beetles have been found multiple times in Oregon and each time were eradicated successfully. The beetles have caused extensive damage on the East coast. They consume over 300 different plant species. If they establish in Oregon, homeowners and crop producers would experience ongoing defoliation events, rising pest control costs, and increased pesticide use. 

Impact: Ornamental and agriculture plants, commercial crops, turf grass 

Cost: “If Japanese beetle becomes established in Oregon…the economic impact to all crops, commodities, and other related businesses could be over $34 million.”

Pathways: Transported via cargo trucks and planes coming from infested parts of the eastern U.S. and through human movement of soils and plants containing beetle larvae.

EDRR: Oregon Department of Agriculture has traps placed throughout Oregon, which they regularly monitor for insect species. In the summer of 2016, 372 Japanese beetles were found in these traps in NW Portland, indicating the presence of a breeding population.
