| Introduction to EDRR |
|
Early Detection and Rapid Response (EDRR) is an approach to invasive species management that focuses on surveying and monitoring at-risk areas to find infestations at their earliest stages of invasion. Along with prevention, this method 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 or containment. Once permanently established, a new invader becomes a long-term management
problem.
