Our next line of defense from invasive species establishment, after prevention, is early detection of entering or small populations and capacity to rapidly and effectively respond. Our strategies include collaborative networks of detectors and responders, promotion of risk evaluation, facilitation of rapid response teams, and ensuring local species prioritization. 



See actions associated with these strategies in the Statewide Action Plan

  1. Develop diverse early detection and rapid response networks emphasizing pathways, cross-jurisdictional partnerships and sharing information.

  2. Promote research that evaluates risks of emerging invasives and identifies current best practices for early detection and rapid response.

  3. Facilitate comprehensive development of rapid response plans and capacity of collaborative response teams.

  4. Support targeted survey and monitoring efforts that uses a pathway analysis.

  5. Support local prioritization of species of concern related to environments at risk and the pathway management approach.

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 million10.”

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.
