Helping to Preserve, Promote, and Protect our Open Space

Explore our open Space

Approximately one third of the area of Thousand Oaks, in California's Conejo Valley, has been designated as permanent public open space. This provides room for native plants and animals to thrive, and vast areas for open space enthusiasts to enjoy.

Wildlife

The Conejo Open Space is home to hundreds of different mammals, birds, insects, snakes, other reptiles, and more! While on the trails, if we are fortunate, we may get to see some of the wildlife.

Volunteer

Our COSCA Volunteer Corps offers many ways for you to help maintain and preserve the open space that surrounds our beautiful Conejo Valley. By joining with other residents of Thousand Oaks, you can make sure that the trails, canyons, and ridgelines will be here for future generations.

Wildflowers

The Conejo Valley is full of Wildflowers. Take a look at our extensive local wildflower photo gallery.

The Conejo Open Space Foundation was formed in 1995 to promote and 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. This web site illustrates ongoing Conejo Open Space programs supported by the Foundation that help preserve and protect our precious open space.
