Early Detection and Rapid Response (EDRR) can stop the spread of new and emerging invasive plant species before they become established. It is one of the most cost-effective and ecologically viable methods for controlling invasive weeds and is well worth the effort to protect Colorado's natural and agricultural resources. This program's success depends on the participation from as many trained eyes as possible. That is why your help is needed to look out for and report new and emerging invasive species.

EDRR Framework & Strategic Plan for Colorado
In June 2016, the Noxious Weed Program staff, along with a team of weed professionals, finalized the new EDRR Framework & Strategic Plan for the state. This document provides goals and objectives for EDRR in Colorado and will be adjusted as those goals are met.
