Boulder Open Space Conservancy

A nonprofit organization

Thank you for showing your support of BOSC and Boulder's open spaces! BOSC will leverage gifts of donation from people like you to protect, enhance, preserve, and steward Boulder's legacy of open space and mountain parks for current and future generations.

During the Spring, the Boulder Open Space Conservancy Board of Trustees approved a new Strategic Plan that focuses on projects to serve Boulder's climate resilience goals. Projects we plan to be working on in partnership with City of Boulder OSMP in the next 2-3 years include Marshall Fire Interpretive Trail, Climate Action Project in partnership with Growing Up Boulder and Columbine Elementary, and Chautauqua Upgrade Project including a Climate Resilience Interpretive Center. Follow BOSC for the latest updates on these important projects. These can all be possible thanks to your generous care and support! 


"We so appreciate this effort initiated by community members who cherish Boulder open space and their deep passion to help our community support and connect with their remarkable public land system," said Tracy Winfree, director of OSMP. "This partnership will help us leverage community support to create new opportunities for community members and our visitors to enjoy and protect their open space."

"Boulder Open Space Conservancy is founded in the belief that these beautiful lands are our shared legacy and our shared responsibility. We believe in the importance of connecting people to the land, and, through that connection, creating a community commitment that will work to preserve it for future generations," said Diane Murphy, BOSC chair. "Together with OSMP, residents and visitors, we will work to continue Boulder's proud legacy of open space conservation and ensure that Boulder's greatest asset - open space - will continue to thrive through community stewardship and investment."


Boulder Open Space Conservancy is a non-profit organization that partners with the City of Boulder Open Space and Mountain Parks to promote and enhance the ecological resilience of our public lands to climate change through sponsorship of conservation projects and community education, for the benefit of all current and future generations of Boulder citizens and visitors.
