Located in the same place as the Living Coast Discovery Center in the Mid-Bayfront Area, just to the west of the Chula Vista suburb, the San Diego Bay National Wildlife Refuge is an important natural space. Home to endangered birds and other animals, visitors can enjoy trails for walks and hikes and seasonally available tours.
The nature center and refuge consists of about 2620 acres of land and water around San Diego Bay and works to protect a wide range of species that fall under the categories of endangered, threatened, migratory, and native. The goal is to protect these species and their habitats as this coastal environment becomes more and more urbanized.
Whether you are a local looking for more unique San Diego experiences or a visitor looking to get off the beaten path -- both literally and figuratively, the San Diego Bay National Wildlife Refuge is an excellent place for a visit. Head over to the south end of San Diego Bay for a day of nature and wildlife.
San Diego Bay
The San Diego Bay is a natural deep-water port and natural harbor in San Diego County. Most people think of this area in relation to its harbor cruises, commercial uses, and naval ties. Still, the bay is good for just about everything one might imagine, including conservation.
You can paddleboard, hire a duffy boat, learn about San Diego’s history, and see certain produce being brought into port from other countries, but you can also hike, commercially fish, whale watch, and learn about plenty of native species.
The third largest of California’s three large, protected bays, coming in after San Francisco Bay and Humboldt Bay. This is one of the best natural harbors on the West coast of North America, having served fleets of military ships during the world wars and continuing to serve as a home port to significant commercial and military assets.
About the San Diego Bay National Wildlife Refuge
The San Diego Bay National Wildlife Refuge is primarily comprised of two different units- the South San Diego Bay and Sweetwater Marsh units. The refuge is located at the south bay, but the north and central bay areas are also rich in natural resources.
The salt marshes are by far the most prominent habitat on this refuge unit and support juvenile fish and invertebrates while providing nesting, foraging, and high-water refuge for many different species of birds.
The additional native habitats on the unit are intertidal mudflats, salt ponds, and a shallow subtidal habitat. These spaces provide resting and foraging habitats for various birds, and the levees surrounding the ponds also offer important nesting habitat spaces for seven species of ground-nesting seabirds to utilize.
Surrounded by the urbanized coastal cities of San Diego, Coronado, Chula Vista, National City, and Imperial Beach, this refuge space is crucial in protecting much of the coastal wildlife that once would have resided in a much larger area.
The San Diego Audubon Society offers monthly and winter tours so the public can experience the South San Diego Bay NWR.
Protecting Endangered and Threatened Species
The San Diego Bay National Wildlife Refuge works to help both plants and wildlife in the coastal Southern California region. The refuge staff work with various habitat management techniques intended to maintain, recover, or enhance plant and wildlife success.
Management techniques are deployed in various ways depending on the needs of the plants or wildlife, as discerned by staff members’ careful assessment.
While the refuge has over 200 species of birds that can be found, it also provides a habitat for four species that fall under the categories of endangered or threatened.
The refuge uses multiple different management and conservation techniques to ensure that species are kept safe, protected, and in a reasonable balance with one another. These programs heavily focus on recovering threatened western snowy plover, endangered salt marsh bird’s beak plant, California least tern, and endangered light-footed Ridgway’s rail. These four species require extra attention and support but are managed along with the other species the refuge supports.
What do recovery actions look like for each of these species?
Least Tern and Snowy Plover:
o Nest site preparation
o Predator control
o Monitoring at the D Street fill within the Sweetwater Marsh Unit
o Salt Works within the South San Diego Bay Unit
Light-Footed Ridgway’s Rail
o Salt marsh restoration
o Population monitoring
o A captive breeding program conducted in partnership with the Living Coast Discovery Center, SeaWorld San Diego, San Diego Zoo’s Safari Park, and more.
There is an essential focus on the community, from support to input on planning and other decision-making processes surrounding San Diego Bay National Wildlife Refuge. They not only welcome but encourage the interest of the public.
It is worth noting that some sensitive areas are closed to the public to support and recover threatened and endangered species by letting the land work with the species in a way that only nature itself can. For example, bird nesting areas might not be available for the public to hike on walking trails, go bird watching, or tour as rehabilitation occurs.
As the goal of the San Diego Bay NWR is to provide a safe haven from surrounding urbanization and urban development, nesting birds can better breed, feed, and rest on land designated to them for this purpose. This is also an essential stop along the Pacific Flyway for nesting birds to avoid overly developed areas during their migration practice.
Following the natural order of restoration, such projects are carefully designed to mimic and model nature, allowing target habitat types to passively develop as they would with no human involvement.
