Mission Statement:  Our mission is to preserve and protect the agricultural, natural, and wildlife habitat areas of Western Colorado by providing leadership and education in the long term management and control of noxious weeds through an integrated, sustainable approach to weed control.

Noxious weeds are presently known to exist in Ouray County.  Weeds are classified according to a state noxious weed priority list:

Classification A:  Eradication is a must.
Classification B:  Manage and control the spread of these species.
Classification C:  Support the use of integrated management methods and provide educational research and biological control resources.

The following are weed species that are present or are of concern to Ouray County (Click on Common Name for picture):
