INTRODUCTION. Hayward Regional Shoreline includes sloughs, marshes, mud flats, and a rocky…read moreshoreline. The word "slough" is pronounced like this: SLOO. In 1854, John Johnson built levees here for the first salt-production facility in the San Francisco Bay area. The salt factory ruins can be viewed by crossing the long footbridge over Highway 92 near the interpretive center. The Interpretive Center and the nearby hiking paths are great places for taking children, teens, and adults, where the goal is to learn a little bit about ecology, botany, zoology, and about the Bay Area's history.
MY PHOTOGRAPHS. My photos are of the mudflats located to the north and west of the Hayward Shoreline Interpretive Center. The photos show pickleweed, which is colored bright red, thick clusters of spartina growing in the mud, industrial equipment that was once used for operating the ponds (ponds once used for collecting salt), and weird formations in the dried earth that resemble volcano craters. Also shown is a photo of me, wearing my University of Wisconsin shirt. To date, I've exhibited landscape photographs at Hayward Shoreline Interpretive Center, three museums, and several galleries, and some of these exhibits are listed here: Hayward Shoreline Interpretive Center, Hayward, CA; Dec. 1992-Feb. 1993; Coyote Point Museum, San Mateo, CA; Jan. 1995-March 1995; Randall Museum, San Francisco, CA; Dec. 1995-Feb. 1996; Crab Cove Visitor's Center, Alameda, CA, San Francisco Bay Area Regional Parks; August 2019; and PhotoLab, Berkeley, CA (Jan. 2020).
BIRDS AND OTHER ANIMALS. Birdwatchers will enjoy their hobby in the grounds near the Hayward Shoreline Interpretive Center. Birds that can be seen in this area include, Canadian geese, Snow geese, Northern Pintail, Mallard, Marbled Godwit, American Avocet, Sandpipers, Seagulls, Crows, Snowy Egret, Great Egret, Great Blue Heron, Black Necked Stilt, Clark's Grebe, and Northern Harrier. Snails and tiny crabs also live here. The salt water harvest mouse (SWHM) lives only in coastal salt marshes. This mouse is naturally adapted to the environment of salt marshes that are dominated by pickleweed. In other environments, this mouse cannot survive. The SWHM has a high ability to drink and to survive on salty water.
PICKLEWEED AND OTHER SALT-TOLERANT PLANTS. The most common plant found in the areas near Hayward Shoreline Interpretive Center is pickleweed, which grows only in salt marshes. The leaves of this plant look like a string of tiny pickles that are attached, end-to-end, to each other. Cordgrass occupies the lower land areas, which are submerged for longer periods of time. Cordgrass (Spartina foliosa) is native to the San Francisco Bay, but most of the cordgrass growing on the Hayward shoreline these days is an eastern species (Spartina alterniflora). The types of plants that grow in various locations in or near a salt marsh depend on the salinity (concentration of salt) and depends on inundation (exposure to incoming water from freshwater tides). At lower elevations where higher salt levels occur, Spartina foliosa, fat hen (Atriplex prostrata), alkali bulrush, alkali heath (Frankenia salina), salt grass (Distichlis spicata), grow in marshes along with pickleweed.
