Grandview Park
Grandview Park, also referred to as Turtle Hill by local residents, is a small, elevated park in the Sunset District, San Francisco, California. It is surrounded by 14th and 15th Avenues, as well as Noriega Street. Despite its small size, or about the size of a city block, the park is important geologically and botanically and offers views of downtown San Francisco, Golden Gate Park, to the Pacific Ocean, the Marin headlands, and across to the Sutro Tower. The summit of Grandview Park rises to about . It is an outcrop of chert, which is part of the heterogeneous assemblage known as the Franciscan Formation, or Franciscan Assemblage, the primary geologic feature on which the city of San Francisco is founded, here covered with a thin layer of sand. It provides one of the last remaining habitats within the city for a number of native plants, including the endangered Franciscan wallflower and dune tansy, and also bush lupin, beach strawberry, bush monkey flower, and coyote bush.

Park
A park is an area of natural, semi-natural or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. Urban parks are urban green space, green spaces set aside for recreation inside towns and cities. National parks and country parks are green spaces used for recreation in the countryside. State parks and provincial parks are administered by sub-national government states and agencies. Parks may consist of grassy areas, rocks, soil and trees, but may also contain buildings and other artifacts such as monuments, fountains or playground structures. Many parks have fields for playing sports such as baseball and football, and paved areas for games such as basketball. Many parks have trails for walking, biking and other activities. Some parks are built adjacent to bodies of water or watercourses and may comprise a beach or boat dock area. Urban parks often have benches for sitting and may contain picnic tables and barbecue gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franciscan Assemblage
The Franciscan Complex or Franciscan Assemblage is a geologic term for a late Mesozoic terrane of heterogeneous rocks found throughout the California Coast Ranges, and particularly on the San Francisco Peninsula. It was named by geologist Andrew Lawson, who also named the San Andreas fault that defines the western extent of the assemblage. The Franciscan Complex is dominated by greywacke sandstones, shales and conglomerates which have experienced low-grade metamorphism. Other important lithologies include chert, basalt, limestone, serpentinite, and high-pressure, low-temperature metabasites (blueschists and eclogites) and meta-limestones. Fossils like radiolaria are found in chert beds of the Franciscan Complex. These fossils have been used to provide age constraints on the different terranes that constitute the Franciscan. The mining opportunities within the Franciscan are restricted to deposits of cinnabar and limestone. The outcrops of the formation have a very large range ...

Monterey Cypress
''Hesperocyparis macrocarpa'' is a coniferous tree. It is commonly known as the Monterey cypress and is one of several species of cypress trees endemic to California. The Monterey cypress is found naturally only on the Central Coast of California. The natural distributional range of the species during modern times is confined to two small relict populations near Carmel, California, at Cypress Point in Pebble Beach and at Point Lobos. Historically during the peak of the last ice age, Monterey cypress would have likely comprised a much larger forest that extended much further north and south.Axelrod, D. I. (1982)AGE AND ORIGIN OF THE MONTEREY ENDEMIC AREA.''Madroño'', ''29''(3), 127–147. Description ''Hesperocyparis macrocarpa'' is a medium-sized coniferous evergreen tree, which often becomes irregular and flat-topped as a result of the strong winds that are typical of its native area. It grows to heights of up to 40 meters (133 feet) in perfect growing conditions, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coyote Bush
''Baccharis pilularis'', called coyote brush (or bush), chaparral broom, and bush baccharis, is a shrub in the family Asteraceae native to California, Oregon, Washington, and Baja California. There are reports of isolated populations in New Mexico, most likely introduced. Distribution and habitat The plants are found in a variety of habitats, from coastal bluffs, oak woodlands, and grasslands, including on hillsides and in canyons, below . Coyote brush is known as a secondary pioneer plant in communities such as coastal sage scrub and chaparral. It does not regenerate under a closed shrub canopy because seedling growth is poor in the shade. Coast live oak, California bay, '' Rhus integrifolia'', and other shade producing species replace coastal sage scrub and other coyote bush-dominated areas, particularly when there has not been a wildfire or heavy grazing. In California grasslands, it comes in late and invades and increases in the absence of fire or grazing. Coyote bush inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bush Monkey Flower
''Diplacus aurantiacus'', the sticky monkey-flower or orange bush monkey-flower, is a flowering plant that grows in a subshrub form, native to southwestern North America from southwestern Oregon south through most of California. It is a member of the lopseed family, Phrymaceae. It was formerly known as ''Mimulus aurantiacus''.''Mimulus aurantiacus''. The Jepson Manual.

Beach Strawberry
''Fragaria chiloensis'', the beach strawberry, Chilean strawberry, or coastal strawberry, is one of two species of wild strawberry that were hybridized to create the modern garden strawberry (''F. × ananassa''). It is native to the Pacific Ocean coasts of North and South America. Description It is an evergreen plant growing to 15–30 centimetres (6–12 inches) tall. The relatively thick leaves are glossy green and trifoliate, each leaflet around 5 cm (2 in) long. The flowers are white, produced in spring and early summer. The fruit, a strawberry, is edible, red on the surface and white inside. Genetics All strawberries have a base haploid count of 7 chromosomes. ''F. chiloensis'' is octoploid, having eight sets of these chromosomes for a total of 56. These eight genomes pair as four distinct sets, of two different types, with little or no pairing between sets. The genome composition of the octoploid strawberry species has generally been indicated as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Franciscan Wallflower
''Erysimum franciscanum'', commonly known as the Franciscan wallflower or San Francisco wallflower, is a plant endemic to the northern California coast, from Sonoma to Santa Cruz Counties. It is a member of the genus ''Erysimum'' in the mustard family, the Brassicaceae. The plant is a biennial or short-lived perennial.Dwyer, DThe Biogeography of the San Francisco Wallflower/ref> The flowers are cream-colored to yellow, with four sepals and four petals arranged in a cross shape, as is characteristic of the Brassicaceae. It flowers from late winter to late spring. The plant prefers open scrubby areas with a fair amount of sunlight, but can flourish on a range of soils including disintegrating serpentine, gravelly and sandy soils. It is fairly easily cultivated in gardens. Although not formally recognized as endangered, the Franciscan wallflower has a limited, discontinuous distribution. It is monitored at the Presidio of San Francisco The Presidio of San Francisco (originally, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
