	Description
	The Whale’s Tail and Old Alameda Creek Complex is a 564-acre site on the eastern shores of the San Francisco Bay Estuary, south of the San Mateo Bridge and bordered to the east by Union City. This area includes remnant marshland patches that predate alterations to the site for salt production, channelized flood control structures, restored salt pond marshland, small sinuous channels, high marsh flats, mudflats, eroding scarp, sand/shell beach, small depositional deltas, and other habitats. The areas included within this complex are entirely restricted from public access and are either managed by California Department of Fish and Game (CDFG) as wildlife habitat (Sub-Areas 13d, 13e, 13f), or by Alameda County Flood Control District for flood control purposes (Sub-Areas 13a, 13b, 13c, 13g). On the northern side of the main channel, formerly diked salt ponds are undergoing restoration activities to convert them to tidally influenced marshlands. To the south of the main channel, Cargill Corporation maintains active salt-producing evaporator ponds. The invasive Spartina at the Whale’s Tail and Old Alameda Creek Complex is one of the oldest infestations of non-native cordgrass in the San Francisco Estuary. The marshlands of this site contain a total of 82 acres of Spartina alterniflora hybrids representing 14.5% of the area. The infestations are establishing in a wide variety of marsh habitats including high marsh pickleweed (Salicornia virginica)/saltgrass (Distichlis spicata), lower marsh Spartina foliosa/mudflat areas, channel banks, edges of salt pans, and bayfront scarps and mudflats. The primary treatment method at this site is aquatic herbicide, which will be applied by conventional spray truck, backpack sprayer, tracked amphibious vehicle, and/or helicopter. Partners on this site include the Alameda County Flood Control District, California Department of Fish and Game, and the California Wildlife Foundation. Note that this is a complex site composed of multiple sub-areas. Please refer to the Site Specific Plan for detailed descriptions of the sub-areas and the associated treatment methods.
