The Refuge headquarters and visitor center is located in the Baylands district of Fremont, next to Coyote Hills Regional Park, in Alameda County. The visitor center is on Marshlands Rd, off Thornton Ave. Most of the refuge stretches along the marshy shoreline north and south of the Dumbarton Bridge, but Bair Island, in San Mateo County, is also part of the system. The southernmost extent of the refuge is in northern Santa Clara County.

Alameda County, California
Alameda County ( ) is a county located in the U.S. state of California.

Alameda County is in the San Francisco Bay Area, occupying much of the East Bay region. The Spanish word ''alameda'' means either "a grove of poplars...or a tree lined street." The name was originally used to describe the Arroyo de la Alameda. The willow and sycamore trees along the banks of the river reminded the early Spanish explorers of a road lined with trees. Although a strict translation to English might be "Poplar Grove Creek," the name of the principal stream that flows through the county is now simply " Alameda Creek." Alameda County is part of the San Francisco–Oakland–Berkeley, CA Metropolitan Statistical Area, and the San Jose–San Francisco–Oakland, CA Combined Statistical Area.

American White Pelican
The American white pelican (''Pelecanus erythrorhynchos'') is a large aquatic soaring bird from the order Pelecaniformes. It breeds in interior North America, moving south and to the coasts, as far as Central America and South America, in winter. Taxonomy The American white pelican was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other pelicans in the genus '' Pelecanus'' and coined the binomial name ''Pelecanus erythrorhynchos''. Gmelin based his description on the "rough-billed pelican" that had been described in 1785 by the English ornithologist John Latham. Latham had access to three specimens that had been brought to London from New York and the Hudson Bay area of North America. The scientific name means "red-billed pelican", from the Latin term for a pelican, ''Pelecanus'', and ''erythrorhynchos'', derived from the Ancient Greek words ( ἐρ ...

Salt Evaporation Pond
A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines. The Salt pans are shallow and large of size because it will be easier for sunlight to travel and reach the sea water. Natural salt pans are geological formations that are also created by water evaporating and leaving behind salts. Some salt evaporation ponds are only slightly modified from their natural version, such as the ponds on Great Inagua in the Bahamas, or the ponds in Jasiira, a few kilometres south of Mogadishu, where seawater is trapped and left to evaporate in the sun. The seawater or brine is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be subsequently harvested. The ponds also provide a productive resting and feeding ground for many species of waterbirds, which may include endangered species. The ponds are commonly separated by levees. Salt evaporation ponds may also be called salterns, salt works or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecotone
An ecotone is a transition area between two biological communities, where two communities meet and integrate. It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). An ecotone may appear on the ground as a gradual blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line. Etymology The word ''ecotone'' was coined by Alfred Russel Wallace, who first observed the abrupt boundary between two biomes in 1859. It is formed as a combination of ''ecology'' plus ''-tone'', from the Greek ''tonos'' or tension – in other words, a place where ecologies are in tension. Features There are several distinguishing features of an ecotone. First, an ecotone can have a sharp vegetation transition, with a distinct line between two communities. For example, a change in colors of grasses or plant life can indicate an ecotone. Second, a change in physiogn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Pablo Bay National Wildlife Refuge
San Pablo Bay National Wildlife Refuge is a National Wildlife Refuge in California established in 1970. It extends along the northern shore of San Pablo Bay, from the mouth of the Petaluma River, to Tolay Creek, Sonoma Creek, and ending at Mare Island. Ecology The refuge encompasses the largest remaining continuous patch of pickleweed-dominated tidal marsh in the northern San Francisco Bay. Historically, the wetlands surrounding San Pablo Bay were one of the largest tidal marsh complexes on the Pacific Coast of North America. However, the area has been significantly impacted by human activities such as hydraulic mining, salt production, diking, draining, filling, agriculture, and development. All told, about 85% of San Pablo Bay's tidal marshes have been altered. In fact, damaged portions these marsh areas and along the Petaluma River were considered as sites for artificial marsh creation using dredged materials. This effort was part of a US Army Corps of Engineers, Waterways ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marin Islands National Wildlife Refuge
The Marin Islands are two small islands, named East Marin and West Marin, in San Rafael Bay, an embayment of San Pablo Bay in Marin County, California.

Ellicott Slough National Wildlife Refuge
The Ellicott Slough National Wildlife Refuge is a United States National Wildlife Refuge located in the northern part of the Monterey Bay area of California. Originally established to protect the habitat of the threatened Santa Cruz long-toed salamander subspecies, Ellicott Slough also harbors other species later federally listed as threatened due to habitat loss, including the California red-legged frog, California tiger salamander and robust spineflower. The refuge was established after the California Department of Fish and Game purchased the property from its original owner. It is made up of four discontinuous units all separated by less than 2.7 miles. The refuge experiences a mild climate influenced by the Pacific Ocean The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions.

Antioch Dunes National Wildlife Refuge
Antioch Dunes National Wildlife Refuge is a sensitive sand dune habitat located near the city of Antioch, California on the south shore of the San Joaquin River-Stockton Deepwater Shipping Channel. It serves as a refuge for three endangered species of plants and insects, and is closed to the public except for tours and events supervised by Refuge staff. The Refuge was established in 1980. It is managed by the U.S. Fish and Wildlife Service. Habitat restoration project A project to restore wildlife habitat, sponsored by the Port of Stockton and implemented by the U.S. Army Corps of Engineers, began during 2013. This work involves dredging sandy spoil from the San Joaquin River and pumping it to the Antioch Dunes. The purpose is to spur population growth of the Lange's metalmark butterfly The process employs a hydraulic cutter-suction dredger, which pumps the sand-water mixture through a fish screen. The mixture flows through a series of berms, which separate the sand from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco Bay Area
The San Francisco Bay Area, often referred to as simply the Bay Area, is a populous region surrounding the San Francisco, San Pablo, and Suisun Bay estuaries in Northern California. The Bay Area is defined by the Association of Bay Area Governments to include the nine counties that border the aforementioned estuaries: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties that do not border the bay such as Santa Cruz and San Benito (more often included in the Central Coast regions); or San Joaquin, Merced, and Stanislaus (more often included in the Central Valley). The core cities of the Bay Area are San Francisco, San Jose, and Oakland. Home to approximately 7.76 million people, Northern California's nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a comp ...
