About Don Edwards San Francisco Bay National Wildlife RefugeThe San Francisco Bay area has had a significant human presence stretching back thousands of years. The earliest residents of the South Bay were the Ohlone, indigenous peoples who lived in ecological balance with their surroundings. The Ohlone were the region's only human habitants for thousands of years, until Spanish settlers emigrated to the area in the late 1700s.
Conversion of wetlands to support development continued well into the 20th century, and today nearly 85 % of the Bay's original marshes and shorelines have been altered. Congressman Don Edwards, responding to concerned local citizens, worked with Congress to approve the purchase of lands for the San Francisco Bay National Wildlife Refuge, which was officially established in 1974. The Refuge was later renamed "Don Edwards San Francisco Bay National Wildlife Refuge" in 1995 in honor of Congressman Edwards' dedication to the Refuge and its mission.

Major
changes occurred in the San Francisco Bay environment following the California
gold rush in 1849. Explosive growth and development placed greater demands on
the sensitive lands surrounding the Bay. The newly introduced salt industry,
for example, converted tens of thousands of acres of salt marsh into commercial
salt ponds.
The urban areas surrounding the
Don Edwards San Francisco Bay National Wildlife Refuge continue to expand.
As a "wildlife island in an urban sea," the Refuge faces unique
challenges. Nearby developments affect the Refuge in many ways. Power lines
and levees criss-cross Refuge grounds. The high cost of land in the Bay area
makes acquiring additional property difficult. Most importantly, Refuge managers and biologists must work
hard to balance different land use practices - habitat and wildlife conservation,
public recreation, and commercial salt production, for example - so that both
the Refuge and the community benefit.
Despite
the difficulties of an urban setting, the Refuge also benefits from and provides
unique opportunities for the surrounding community. Local partner organizations
aid the Refuge in acquiring sensitive habitats for migratory birds, and threatened
and endangered species. An extensive network of community volunteers (including
high school students, corporate employee volunteers, and retirees) provide invaluable support to Refuge
staff. School groups take advantage of Refuge educational activities,
teachers attend orientations that prepare them for environmental education,
and people of all ages come to enjoy a wide variety of weekend interpretive
programs which provide further opportunities for wildlife-oriented recreation.Last updated:
