Interested in volunteering?

Jeffco Open Space has been the natural choice for volunteering since 1972. Ever since a grassroots campaign resulted in the creation of our agency, volunteers have been pitching in for their parks – from helping to preserve natural resources and educating visitors to blazing new trails.

Conservation Awards

The celebration of the 2021 Jeffco Open Space Conservation Awards hosted almost 300 individuals virtually on Thursday, January 28. This year, in lieu of awards, we recognized individuals, organizations, and partners for their contributions to the JCOS mission with a video. 2020 was a challenging year. Together with our partners and volunteers, JCOS has endured and accomplished exceptional things. Since the onset of the pandemic, our visitors have looked to us for a place to escape and recreate. Consequently, our visitation has skyrocketed. Our parks are feeling the pressure, and our team continues to rise to the occasion. Collectively, we continue to provide a place for those who need it, a safe outdoor experience for all to enjoy.
