The Tijuana River National Estuarine Research Reserve preserves one of the
largest remaining examples of coastal wetland habitats in the southern
California sub-region. The 2,293 acre Tijuana River Reserve is located in
Imperial Beach, Calif., situated in a highly urbanized location, 15 miles
south of San Diego and immediately adjacent to Tijuana, Mexico. Three quarters
of the reserve's watershed is in Mexico, so reserve programs apply an
international perspective to critical issues of habitat restoration,
endangered species management, wastewater from Mexico, sediment management,
and recreational use. The reserve is a home to eight threatened and endangered
species of plants and birds and is recognized as a wetland of international
importance' by the Ramsar Convention.

**San Diego Bay National Wildlife Refuge**

The San Diego Bay National Wildlife Refuge protects a rich diversity of
endangered, threatened, migratory, and native species and their habitats
within a highly urbanized coastal environment. The refuge is located at the
south end of San Diego Bay and is surrounded by the cities of National City,
Chula Vista, San Diego, Imperial Beach, and Coronado. Established to protect
endangered and threatened species, the refuge encompasses approximately 2,620
acres of land and water in and around San Diego Bay.

Nesting, foraging, and resting sites are managed to support a wide variety of
bird species. Waterfowl and shorebirds overwinter or stop here to feed and
rest as they migrate along the Pacific Flyway. Undisturbed expanses of
cordgrass-dominated salt marsh provide sustainable habitat for the light-
footed Ridgway's rail.

Enhanced and restored wetlands offer high-quality habitat for fish, birds, and
coastal salt marsh plants, including the endangered salt marsh bird’s beak.
Quiet nesting areas, buffered from surrounding urban development, help ensure
the reproductive success of the threatened western snowy plover, endangered
California least tern, and other ground-nesting seabirds and shorebirds.

The refuge also offers the public opportunities to observe birds and wildlife
in their native habitats and to connect with the natural environment.
Environmental education and interpretive programs help expand public awareness
of the refuge’s rich wildlife resources. The San Diego Bay National Wildlife
Refuge is a haven for both wildlife and people, to be valued and protected for
generations to come.

The refuge consists of two units: the Sweetwater Marsh Unit and the South San
Diego Bay Unit. These areas preserve most of what remains of San Diego Bay’s
historic coastal salt marsh and intertidal mudflat habitat.

**Sweetwater Marsh Unit**

Sweetwater Marsh covers 316 acres and was established in 1988 on the east side
of San Diego Bay. This area has a rich cultural history. The Kumeyaay people
originally used the marsh for fishing, hunting, and gathering. During World
War I, a 30-acre kelp processing plant on the site produced potash, a key
ingredient in smokeless gunpowder, for the British Army. This area is now
known as “Gunpowder Point.” Today, the marsh is not only home to native
wildlife but also serves as the headquarters for the San Diego National
Wildlife Refuge Complex.

Habitats at Sweetwater Marsh support species such as the California least
tern, western snowy plover, osprey, belted kingfisher, and Palmer’s frankenia,
a rare salt marsh plant found in few other places.

The refuge is also the site of a successful breeding program for the
endangered light-footed Ridgway’s rail, conducted in partnership with the
Living Coast Discovery Center, SeaWorld San Diego, and the San Diego Zoo
Safari Park. Hundreds of rails have been reared and released into the wild
through this program. Visitors can see a variety of native birds up close in
aviaries and during educational presentations led by volunteers and staff at
the nature center. Environmental education programs, activities, and special
events are offered throughout the year by the refuge complex and the nature
center. It is a great place to visit.

**South San Diego Bay Unit**

Dedicated in 1999, the 2,300-acre South San Diego Bay Unit was established to
protect and restore habitat for hundreds of thousands of birds migrating along
the Pacific Flyway, as well as for resident species. This unit is located at
the southernmost tip of San Diego Bay, within the cities of Imperial Beach,
Coronado, National City, and San Diego.

Eelgrass beds and the largest contiguous mudflat in southern California
provide essential foraging habitat for overwintering waterfowl, seabirds,
shorebirds, and migrating Pacific green sea turtles. The unit also supports
nesting seabirds in spring and summer, including endangered and threatened
species such as the California least tern, Belding’s savannah sparrow, and
western snowy plover.

Ongoing restoration of tidal flats, salt marsh, subtidal, and native upland
habitats continues to create essential habitat for birds, native plants, fish,
and other marine life.

The public can enjoy birdwatching, walking, and biking along the Bayshore
Bikeway, or join monthly guided tours of the refuge. Hundreds of
schoolchildren visit each year to participate in environmental education
programs that use the refuge as an outdoor classroom.

San Diego National Wildlife Refuge is not only a haven for wildlife but also a
natural retreat for nearby communities. Established in 1996, the refuge spans
more than 12,445 acres from the city of Jamul to neighborhoods in Spring
Valley and eastern Chula Vista. It represents the U.S. Fish and Wildlife
Service’s contribution to the San Diego Multiple Species Conservation Program
(MSCP), a regional plan designed to protect habitats and species while
supporting responsible development.

Management of the refuge is guided by ongoing biological surveys and
endangered species monitoring programs. These efforts are supported by
nonprofit partners and cooperating agencies to achieve the goals outlined in
the Comprehensive Conservation Plan.

The refuge includes open grasslands, cool river corridors, and oak woodlands,
many of which are being actively restored after years of degradation from
human activity and wildfire. Public trails are maintained for hiking, mountain
biking, and horseback riding while ensuring protection for the sensitive
species that call the refuge home.
