Early Detection & Rapid Response
Early Detection and Control of New Invading Weeds
  • A primary Program objective for Oregon Department of Agriculture
  • Identify new invader prior to widespread establishment or introduction
  • Eradicate or contain new invading weeds
  • Increase awareness of new invaders with partners and public.
Prevention and treatment of new noxious weed introductions is the most successful, cost effective, and least environmentally damaging means of control.  If new invasive noxious weeds are allowed to go unchecked, economic losses will exceed the present control costs of eradication or containment by several orders of magnitude.  After initial introduction of a new invasive plant, there is a short period of opportunity for eradication and containment.  Once permanently established, a new invader becomes a long-term management problem.

Example: Purple starthistle
Current infestation > 1 acres
Potential to invade 1.5 million acres
Potential economic impact $12 million per year
