Gabriels Projects: Galster Wilderness Park Nature Center

7 Million year old fossil eel found in Galster ParkSGMRC's newest Nature Center is designed with a focus on environmental and watershed education. Something is planned for everyone! Help us cure Nature Deficit Disorders. The Nature Center is due to open in early 2008.

On the north slope of the San Jose Hills in a heavily urbanized area of Los Angeles County, Galster Wilderness Park is one of the last remaining large woodlands of Southern California Black Walnut Trees. The several hundred acres of habitat are covered by native plants, such as, lemonadeberry (Rhus integrifolia), toyon (Heteromeles arbutifolia), along with the unique Southern California Black Walnut (Juglans californica). Areas of Coastal Sage Scrub, another plant community in decline, include native plants, such as, California Sagebrush (Artemisia californica), White Sage (Salvia apiana), California Encelia (Encelia californica), and California Buckwheat (Eriogonum fasciculatum). The two dominant plant communities provide essential habitat for a large diversity of birds, mammals, reptiles, and invertebrates.

Programming needs are dependent on volunteers to serve as docents, trail guides, office personnel, program presenters, and program assistants. We look forward to hearing from you.

Remember to Visit & Volunteer!

If you would like to ask us about how you can become a volunteer, or to be notified by e-mail of scheduled events at the Nature Center, please add yourself to our mailing list.
