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.
