Invasive Species Management

The Jefferson County Invasive Species Management program helps the public by developing integrated management plans to control forest insect pests and noxious weeds. The program coordinates with private entities and local, state, and federal governmental agencies to achieve regional pest control.

This site includes information to help identify, control and prevent forest pests and noxious weed infestations. Our goal is to educate the public about weed and pest problems and offer solutions.


cheatgrass white


Cheatgrass is a Colorado List C noxious weed.  This annual is starting to germinate and will overwinter as a seedling. It reproduces by seed.  This aggressive invader moves into grasslands and meadows and can form thick monocultures. 
​Removal or control with herbicide is very effective this time of year.
