Cheatgrass Control Cost Share

Jeffco Invasive Species Management is pleased to announce a new cost share program for 2023.

We have been fortunate to receive federal grant funding for stewardship programs to help landowners care for their land by controlling non-native invasive Cheatgrass.  

What It Is

Cheatgrass is a winter annual grass that emerges earlier than our native grasses and wildflowers.  It forms large monocultures and reduces food and habitat that livestock and wildlife rely on.  Cheatgrass also dries earlier in the season and can become a fire hazard.  Colorado has designated it as a List C noxious weed.

The Project

  • The project will focus on privately owned properties of 35 acres or more in the north-west portion of the county.  Map
  • Funding is available for control of Cheatgrass based on a 50:50 cost match and is limited to $1500.
  • Applications will be accepted until August 15th. 
  • Application review will include a consultation and site visit.  
  • Control must be done by October 1st.
  • Applicants will submit a Request for Reimbursement which will be due by November 1st.

Properties must be:

  • Within un-incorporated Jefferson County within the Project Area. Map
  • A minimum of 35 acres
  • Privately owned
