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.

### Overview

The Cosumnes River Preserve Visitor Center is the focal point for the majority
of public access and education at the Preserve. The deck and outdoor exhibits
are open to the public even when the indoor exhibit room is closed to in-
person visits. The trails, boardwalks, and waterways are the only parts of the
Preserve that are open to the general public. These areas are open from
sunrise to sunset. The Preserve promotes low-impact recreation and offers
naturalist-led activities that include hikes, bird monitoring, paddles,
photography walks, and more.

The Cosumnes River Preserve features a dock for you to launch your canoe or
kayak from. The river offers flat water, allowing for excellent boating
opportunities throughout most of the year. Paddlers can enjoy a scenic guide
through the river sloughs and the main channel, cruising along riparian forest
and oak woodland and moving through wetlands teeming with wildlife.

### Overview

The Cosumnes River Preserve is home to California's largest remaining valley
oak riparian forest, and is one of the few protected wetland habitat areas in
the state. The Preserve includes over 50,000 acres of central valley
grasslands, vernal pools, wetlands, and valley oak forests.

Nestled in the heart of California's Central Valley, the Preserve is a
critical stop on the Pacific Flyway for migrating and wintering waterfowl.
Over 250 species of birds have been sighted on or near the Preserve, including
the State-listed threatened Swainson hawk, greater and lesser sandhill cranes,
Canada geese, and numerous ducks. The Cosumnes is the last free-flowing river
from the mighty Sierra Nevada Mountains into the Great Central Valley.

### Hunting and Shooting Info - Cosumnes River Preserve:

Hunting, fishing, and camping are not allowed at the Cosumnes River Preserve.
In general, there is no hunting allowed in the core area of the Preserve
because it is not compatible with our public use and wildlife protection
objectives.

Hunting and fishing are allowed on the river and in the sloughs, but **hunters
and fishers must stay in their boats (no bank fishing/hunting).** It is legal
to fish or hunt from a boat in the river, in a state navigable waterway, but
only during the proper seasons and with the proper licenses.

  * Special scheduled hunts available by permit.
  * Youth and mobility-impaired hunters contact CRP @ (916) 684-2816
  * BLM Lands within the Cosumnes River Preserve ACEC boundary are CLOSED to hunting and target shooting.

NOTE: All California game species are regulated by the California Department
of Fish and Wildlife (CDFW). Rules, regulations, and seasons are controlled by
CDFW, and it is the hunter's responsibility to verify and comply with proper
species, seasons, zones, regulations, and legal location if hunting on public
lands.

_FGC 3004 — It is unlawful for any person to hunt or discharge while hunting,
any firearm or other deadly weapon within 150 yards of any occupied dwelling
house, residence, or other building or any barn or other outbuilding used in
connection therewith. The 150-yard area is a "Safety Zone."_

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.
