Wildlife Volunteers Mission Statement
The Wildlife Volunteers are an “elite” group of caring people of all ages striving to improve the quality of life for birds and wildlife in the East Bay Regional Park District. We are dedicated to assisting the East Bay Regional Park District’s Stewardship staff with protecting, managing, conserving and enhancing the region’s important scenic and natural resources. Wildlife Volunteers renew their connections to the land through sciences-based, hands-on conservation and resource management activities.
Please give some careful thought to the schedule of “Group Activities” you would most like to help with, and then call the District’s Reservation Department at (888) 327-2757, option 2, to sign-up. Also, please give us at least two weeks' notice and a phone number where we can leave you a voice-mail message. Based on weather conditions, or other unseen circumstance, projects can be cancelled.
