Helping to Preserve, Promote, and Protect Our Open Space
The Conejo Open Space Foundation is a 501(c)(3) nonprofit corporation formed in 1995 to promote, support and help maintain the open space and trail system of the Conejo Valley and to educate residents as to their roles as custodians and protectors of the open space and the environment.
COSF is funded through individual, business, and corporate memberships, donations and grants. Funds received by COSF are highly leveraged through the extensive use of unpaid community volunteers and other in-kind donations.
This website illustrates ongoing programs sponsored by the Conejo Open Space Conservation Agency and supported by the Foundation that help preserve and protect our precious open space.
We volunteer to protect and preserve our precious open space. One great way to do this is by educating the youth of our community. Interested in working with Conejo Valley fourth graders? Join us at our next Trails Education Days.
The Conejo open space wouldn't be the same without the hundreds of people who give their time and energy. The COSCA volunteer corps offers many ways to stay involved in the open space. Join us and make a difference today!
