curriculum through hands-on, land-based learning in small groups. Follow-up projects integrate knowledge
with a sense of empowerment and social responsibility.
Community Education and Outreach: Volunteer environmental stewardship events
and weekly volunteer teams
in two locations, conservation interpretive activities involve citizens directly in their local conserved lands.
Quarterly newsletters and annual fire safety information for wildland-urban interface neighbors inform over 1,000
supporters about their nearby conserved lands and how to keep them healthy. Crestridge Reserve Rangers
volunteer patrol and Crestridge Eyes on the Land reporting system involve recreation users of this reserve in
keeping the land managers informed about safety and habitat issues.
