Conejo Open Space Foundation

Conejo Open Space Foundation The Conejo Open Space Foundation was formed in 1995 to promote and maintain the open space and trail

A significant goal for the Conejo Open Space Foundation (COSF) is educating the public about the Conejo Valley's extensive trail system, and about the plants and animals living in the Conejo Open Space. Educational projects include:

- Trails Education Days -
The Conejo Open Space Foundation supports the Conejo Open Space Trails Advisory Committee (COSTAC) in coordinating an annual environmental e

ducation program for Conejo Valley fifth graders. More than 30,000 students have taken part in Trails Education Days since its inception in 1992. For more information, see the Trails Education Days page on cosf.org

- Community Outreach -
Foundation volunteers periodically set up information tables at local trailheads and at local events to hand out trail maps, and to provide education and information about the extensive open space in the Conejo Valley.

- On The Edge -
COSF joins the National Park Service and On the Edge in a wildlife and community fair open to the public. The focus of the event is to teach us how to co-exist with our wild neighbors, and how to lessen our impact on the environment. We are all living "on the edge" where our wilderness and urban areas meet.

- Earth/Arbor Day -
The Foundation hosts an information booth at the Conejo Valley's Annual Earth Day/Arbor Day festival. This event makes environmental education fun for the whole family.

- Career Fair -
The Conejo Open Space Foundation participates in the annual Conejo Valley Unified School District's Career Fair, which is open to students of all ages. The Foundation provides information on environmental careers, and has been joined by environmental professionals including Park Rangers, a Land Use Planner for the City of Thousand Oaks, an urban anthropologist, and a cultural resource manager.

- COSF Website -
Our website is a resource designed to educate and inform our community about the Conejo Open Space. It provides education and information about the Conejo Open Space, including trail maps, open space photos and videos, descriptions of plant and animal life, a listing of group outings, favorite hike routes, volunteer opportunities, contact information, and much, much more.
