About CTC

The Colorado Tree Coalition is a volunteer organization whose mission is “leading statewide efforts to preserve, renew, and enhance community forests.” The CTC Executive Committee and Board met in August of 2011 and updated the CTC’s 5-year Strategic Plan.

Increased funding from the Community Forestry Assistance Act in the early 1990’s allowed the Colorado Tree Coalition (CTC) to grow from modest beginnings as a group of metro foresters into a statewide non-profit. The CTC incorporated in 1995 with a mission to lead statewide efforts to preserve, renew and enhance community forests. Since incorporating as a non-profit in 1995, the Colorado Tree Coalition (CTC) has grown, branched out and extended our reach to all corners of Colorado and into neighboring states.

The Colorado Tree Coalition (CTC) is a volunteer, non-profit 501(c)(3) organization who works closely with partners such as the U.S. Forest Service, Colorado State Forest Service, Xcel Energy, and several corporate and private sponsors. The CTC provides programs and services to communities across Colorado. Programs administered by CTC include the Champion Tree, Tree Risk Assessment and Fifth Grade Arbor Day Poster Contest programs. Additionally, the Trees Across Colorado program provides low cost trees to Colorado communities, and the ReForest Colorado program helps communities recover from natural disasters. CTC is a membership driven organization, and it encourages individuals, organizations, and communities across Colorado to become a member and get involved.

Learn about all the Colorado Tree Coalition programs with this narrated PowerPoint presentation created by Susan Hardin.



The executive Committee is responsible for the day to day operations of the Colorado Tree Coalition and is selected by and from the Board of Directors.


The accomplishments of the Colorado Tree Coalition are due to the help and support of the Board of Directors and the hard-working programs and committee members.

The Board of Directors is the managing group of the organization.  It is comprised of chapter members, invited representation from tree related organizations, and the immediate past president.

If you are interested in volunteering for a specific program or have any questions regarding a Colorado Tree Coalition program please contact the Program Leader by e-mail.
