San Mateo (/ˌsæn məˈteɪ.oʊ/ SAN mə-TAY-oh; Spanish for “Saint Matthew”) is a city in San Mateo County, California, approximately 20 miles (32 km) south of San Francisco, and 31 miles (50 km) northwest of San Jose. San Mateo had an estimated 2017 population of 104,748.
The best-known natural area is Coyote Point Park, a rock outcropped peninsula that juts out into the San Francisco Bay. The early Spanish navigators named it la punta de San Mateo. Crews of American cargo ships carrying grain in the bay renamed it Big Coyote (BLM, 1853). Sailors had a penchant for naming promontories at the edge of San Francisco Bay after the coyote; across the bay in Fremont are the Coyote Hills, part of Coyote Hills Regional Park. By the 1890s the shore area was developed as a popular beach called San Mateo Beach. In 1842 the Spanish had named it playa de San Mateo. Today Coyote Point is home to CuriOdyssey, formerly known as the Coyote Point Museum, a major natural history museums and wildlife centers in the state. The Peninsula Humane Society is also situated at Coyote Point.
The variety of natural habitats includes mixed oak woodland, riparian zones, and bayland marshes. One endangered species, the California clapper rail, was sighted feeding on mudflats by the Third Avenue bridge in San Mateo. The marsh areas are also likely habitat for the endangered Salt Marsh Harvest Mouse, which inhabit the middle and high zones of salt and brackish marshes, as well as for the endangered marsh plant, Point Reyes bird’s beak.
Sugarloaf Mountain, whose name has been documented in 1870, is a prominent landform between the forks of Laurel Creek (Brown, 1975). In the late 20th century, this mixed oak woodland and chaparral habitat was a site of controversy related to proposals to develop a portion of the mountain for residential use. It has been preserved for use as park and open space area, and is home to the endangered Mission Blue Butterfly.
Sawyer Camp Trail, located on the western edge of San Mateo along the Crystal Springs Reservoir is another popular destination for joggers, walkers and bikers. This roughly 6 mile trail begins in San Mateo and stretches north toward Hillsborough and San Bruno, parallel to the 280 freeway.
