Become an Open Space Trail Watch Volunteer (TWV). TWV act as the "eyes and ears" for Open Space, reporting wildlife and visitor activities, maintenance needs, suspicious activity and other vital information occurring in the field. Volunteers may patrol by foot, bike or horse. TWVs are also important public educators, informing visitors on the role of the Open Space Division and encouraging responsible use of the resource. Volunteers often contribute to conservation projects and supplement operations, too.
