Map Satellite This is one, if not the only, remaining natural freshwater marshland in the southern San Joaquin Valley. Plants found in or alongside the marsh include common tule, Scirpus acutus, California amaranth, Amaranthus californicus, arrowhead, Sagittaria longiloba, and the yellow water weed, Ludwigia peploides. Sandbar willow, Salix hindsiana, is found along the streamside. The non-native red brome, Bromus madritensis ssp. rubens, and the rare plants Tuctoria greenei and Fritillaria striata are found in the grasslands. Marsh hawks, Circus cyaneus, are common year-round, and pintail and blue-winged teal, Anas acuta and Anas discors, are winter residents. Numerous other birds breed or visit here. There is also an extensive colony of the Pacific tree frog, Hyla regilla. Integrity: The land is privately owned by several individuals and firms. Portions are grazed. To protect the marsh, monitoring the water quality to prevent contamination from the Poso Creek oilfields is imperative; however, the halting of all water discharge may result in drying-up of the marsh. Use: Research, educational, light grazing January 1975
