Antioch Dunes National Wildlife Refuge is the only national wildlife refuge in
the country established to protect endangered plants and insects – the Antioch
Dunes evening primrose, the Contra Costa wallflower, and the Lange’s metalmark
butterfly.

Created in 1980, the 55-acre refuge was once part of a larger sand dune system
that stretched two miles along the southern bank of the San Joaquin River east
of the City of Antioch. The sand dunes were formed by ancient deposits of
glacial sands carried downriver from the Sierra Nevada. Over thousands of
years, ocean winds and bay tides slowly shaped these aeolian (wind-blown)
sands into dunes that approached 120 feet in height. Isolation of these dunes
resulted in the development of species of plants and insects that were found
nowhere else in the world. In 2022, another 12 acres were added to the refuge
bringing the total area to 67 acres.

Large-scale sand mining and industrial development fragmented the sand dune
habitat until only a small portion of the original ecosystem remained. What is
left today are two disjunct parcels (the Stamm and Sardis Units) containing
sand dunes varying from 0-50 feet high, making up refuge.

Due to the sensitivity of the habitats and the endangered species, the refuge
is not open to unsupervised use by the public. However, refuge staff and local
educators conduct on-site environmental education efforts through monthly
guided tours and special events. Volunteers also regularly assist refuge staff
with habitat restoration projects and endangered species surveys.

Contra Loma Dam and reservoir are part of the Central Valley Project - Delta
Division and offers recreational opportunities for the East Bay area near San
Francisco. Numerous hiking trails exist as part of the facility and the area
provides excellent access to the Contra Costa Canal Regional Trail. The trail
system provides for bikes, equestrian and pedestrian use and are available
from 5:00 am to 10:00 pm daily. The park also provides picnic and other day
use facilities and adjacent to the Antioch Municipal Golf Course.

On July 17, 1944, a massive explosion jolted the San Francisco East Bay area,
shattering windows and lighting up the night sky. At Port Chicago Naval
Magazine, 320 men were killed instantly when two ships loading ammunition for
Pacific troops exploded, resulting in the worst home front disaster of WWII.
The aftermath illuminated the issues of segregation and racial inequality in
the military.

The San Francisco Bay National Estuarine Research Reserve comprises two
components located along the salinity gradient of the San Francisco Bay. The
reserve's 3,710 acres are located at China Camp State Park in San Rafael and
Rush Ranch in Suisun City, 30 miles north and 50 miles northeast of San
Francisco, respectively. A primary focus of the reserve is to support tidal
marsh restoration through research, monitoring and education. These sites
serve as valuable reference sites in the San Francisco area where nearly 97
percent of the historic tidal wetlands have been lost due to development
pressures in the region. These reference sites create an opportunity for a
scientific basis for restoration activities in the bay area.
