Bair Island: A Gem in the San Francisco Bay
The Geographic and Historical Context
Located within Redwood City and in close proximity to the San Francisco Bay, Bair Island has a rich history. It was once used for salt production before being designated as an ecological reserve. The island consists of three distinct parts: Inner, Middle, and Outer islands, surrounded by the Steinberger Slough to the northwest and Redwood Creek to the southeast.
Wetland Restoration Efforts
Bair Island has undergone significant wetland restoration projects to revitalize its tidal marsh ecosystem. These efforts have been crucial in preserving the island’s natural habitat and supporting the diverse array of species that call it home. The restoration work has been a collaborative effort between various organizations, including the Don Edwards San Francisco Bay National Wildlife Refuge and the Peninsula Open Space Trust.
Tidal Marsh and Its Ecosystem
The tidal marsh on Bair Island is a unique and vital ecosystem that supports a wide range of wildlife. These marshes are characterized by their dynamic nature, with the ebb and flow of tides shaping the landscape and creating diverse habitats for plants and animals. The restoration of these tidal marshes has been a key focus of conservation efforts on the island.
Wildlife Habitat: A Sanctuary for Species
Endangered Species on Bair Island
Bair Island is a sanctuary for several endangered species, most notably the California clapper rail and the salt marsh harvest mouse. These species rely on the island’s tidal marshes for their survival, and the ongoing conservation efforts aim to protect and expand their habitats. The restoration projects have been instrumental in providing these endangered species with the necessary conditions to thrive.
The Pacific Flyway: A Crucial Avian Highway
Bair Island plays a significant role in the Pacific Flyway, a major migratory route for birds spanning from Alaska to South America. The island’s diverse habitats, including its tidal marshes and sloughs, provide essential stopover sites for numerous migratory bird species. This makes Bair Island a prime location for bird watching and nature photography enthusiasts.
Marine Life and Habitat
In addition to its avian residents, Bair Island is home to a variety of marine life. Harbor seals can be found in the waters surrounding the island, particularly in Corkscrew Slough. The slough’s unique configuration creates a sheltered environment that is ideal for harbor seals to rest and nurture their young. The presence of these marine mammals highlights the ecological significance of Bair Island and its surrounding waters.
Bair Island and Human Interaction
Public Access and Recreation
While much of Bair Island is dedicated to wildlife conservation, there are opportunities for the public to enjoy and explore this natural wonder.

These trails provide a great opportunity for environmental education and fostering a deeper appreciation for the importance of conservation.
The Role of Local Organizations
The protection and restoration of Bair Island have been made possible through the efforts of local organizations. The Peninsula Open Space Trust has been a key player in the conservation of the island, working in collaboration with the Don Edwards San Francisco Bay National Wildlife Refuge. These organizations have been instrumental in securing funding, coordinating restoration projects, and engaging the community in the protection of this valuable ecosystem.
Bair Island in the Context of Urban Estuary
Bair Island’s location within an urban estuary presents both challenges and opportunities for conservation. The island’s proximity to urban development means that it faces pressures from human activities, such as pollution and habitat fragmentation. However, it also serves as a model for how urban estuaries can be effectively managed and protected. The success of Bair Island’s restoration efforts demonstrates the potential for balancing human needs with the conservation of critical ecosystems.
