Open Space Background

Walnut Creek Open Space Guides and Interesting Information

The more you know about the Open Space, the more you will enjoy being there and seeing what's in it. To this purpose we have created several articles on interesting topics associated with natural history, wildlife, and our Open Spaces. There are also several wildflower guides that were created in 2004 and 2009 to give you a reference to what native plants can be seen in various locations.

If you have any questions or suggestions for topics you would like to see covered, please contact Us.
