Colorado Outdoor Stewardship Coalition

Outdoor stewardship is stronger when we work together.


The Colorado Outdoor Stewardship Coalition (COSC) is a collaboration of nonprofit stewardship organizations and federal, state, and local land managers that promotes stewardship of Colorado’s outdoors, elevating the awareness and engagement of all Coloradans in caring for the state’s outdoor spaces. Hosted by Volunteers for Outdoor Colorado, the Coalition has been working since 2010 to organize forums for stakeholder organizations and to document and convey the collective impact of outdoor volunteer stewardship.

In 2017 COSC launched on the Statewide Stewardship Initiative (SSI). This effort aims to build the vital long-term stewardship infrastructure Colorado needs to sustain its outdoor recreation and natural resources. The goals of the initiative are to help establish best practices and tools that foster strong and sustainable programs capable of responding to Colorado’s growing stewardship needs. Learn more about the Initiative.

The Coalition also commissioned a study in 2014 – Caring for Colorado Public Lands – that identifies conditions facing both Colorado public land managers and volunteer stewardship organizations in their collective efforts to maintain the state’s outdoor resources and Coloradans’ quality of life. Implementing strategies that expand stewardship on Colorado’s public lands remains a top priority for the Coalition.
