Volunteering at the Open Space Authority brings people together in a beautiful setting to work and have fun. Whether they’re helping visitors, working to improve habitat, or leading interpretive hikes, volunteers play a vital role in the Authority’s mission. OSA has a number of activities to choose from.

Resource volunteers serve on the trail patrol or contribute to land stewardship projects. Community Outreach volunteers represent OSA at booth events and speaking engagements. Resource and Community Outreach volunteers are trained and supervised by the Volunteer Programs Supervisor. Interpretive volunteers help with hikes, camps and special events under the guidance of the Coordinator of Interpretive Programs. Most volunteer roles have a minimum age requirement of 18 or over. Teens aged 14-17 may serve in the Land Stewards program with a parent or legal guardian present.

Volunteer Overview

Trail Patrol – Enjoy and Protect
Get out on the trail and serve as a resource to hikers and OSA staff. Members of the Trail Patrol program distribute information, brochures, and maps to trail users, educate visitors about proper trail use and safety, and provide staff with information on trail conditions and visitor use patterns. Patrol can be done on foot, bicycle, or horseback following trail use regulations. Trail Patrol Members commit to patrolling OSA lands a minimum of once a month.

Community Outreach – Fun and Fairs
Put your “people skills” to work for open space preservation. Community Outreach Volunteers represent OSA at community festivals, health fairs, and other public events. Activities include staffing the Open Space Authority display, answering questions, leading fun educational games, and sharing information.

Land Stewards – Restore and Preserve
Get your hands dirty and affect a positive change on open space lands. Volunteers for the Land Steward’s program aid OSA staff with trail maintenance and construction, restoration, fencing, and cleanup projects. All training is provided. This is a great opportunity for people who are interested in volunteering for just one day, or for several projects.

Docents – Educate and Share
Share your love of nature and the outdoors with others. Docents talk about the natural environment, leading groups on fun and informational hikes on Open Space lands. Each docent receives training on leading group hikes, and on information specific to each area. Docents commit to leading/assisting one hike per quarter.

Special Projects – Skills and Experience
Use your unique skills to benefit the environment. Special Projects may include conducting plant or wildlife inventories, updating maps, serving as photographer during OSA events, or helping with clerical tasks in the office.


Many thanks to all the volunteers who contribute their time and talent to support the Open Space Authority.
