Arctostaphylos Franciscana
''Arctostaphylos franciscana'', known by the common name Franciscan manzanita, is a species of manzanita. It was named by Alice Eastwood and is native to the city of San Francisco. Taxonomy Franciscan manzanita was formerly considered as a subspecies of Hooker's manzanita until elevated to full species rank following modern genetic analysis and comparisons. Conservation When the Laurel Hill Cemetery in San Francisco was bulldozed in 1947, it was thought that the Arctostaphylos franciscana went extinct. In 2009, one wild specimen of the shrub was discovered in the Presidio by a local conservationist. Less than a month later, Caltrans transplanted this specimen to make way for the Doyle Drive Replacement Project. The U.S. Fish and Wildlife Service designated the Franciscan manzanita as an endangered species on October 5, 2012. The National Park Service and Golden Gate National Parks Conservancy are attempting to cross-pollinate and propagate the preserved specimen in order to ...

Arctostaphylos
''Arctostaphylos'' (; from "bear" and "bunch of grapes") is a genus of plants comprising the manzanitas () and bearberries. They are shrubs or small trees. There are about 60 species, of ''Arctostaphylos'', ranging from ground-hugging arctic, coastal, and mountain species to small trees up to 6 m tall. Most are evergreen (one species deciduous), with small oval leaves 1–7 cm long, arranged spirally on the stems. The flowers are bell-shaped, white or pale pink, and borne in small clusters of 2–20 together; flowering is in the spring. The fruit are small berries, ripening in the summer or autumn. The berries of some species are edible. ''Arctostaphylos'' species are used as food plants by the larvae of some Lepidoptera species including '' Coleophora arctostaphyli'' (which feeds exclusively on ''A. uva-ursi'') and '' Coleophora glaucella''. Distribution Manzanitas, the bulk of ''Arctostaphylos'' species, are present in the chaparral biome of western North Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alice Eastwood

She is credited with building the botanical collection at the California Academy of Sciences, in San Francisco. She published over 310 scientific articles and authored 395 land plant species names, the fourth-highest number of such names authored by any female scientist. There are seventeen currently recognized species named for her, as well as the genera ''Eastwoodia'' and '' Aliciella''. Biography Alice Eastwood was born on January 19, 1859, in Toronto, Canada, to Colin Skinner Eastwood and Eliza Jane Gowdey Eastwood. When she was six her mother died. The children were cared for by various relatives, and for a time, Alice and her sister were placed at the Oshawa Convent in Toronto.

Laurel Hill Cemetery (San Francisco, California)
Lone Mountain Cemetery was a complex of cemeteries in the Lone Mountain (California), Lone Mountain neighborhood of San Francisco, California on the land bounded by the present-day California Street, Geary Boulevard, Parker Avenue, and Presidio Avenue. Opened 1854, it eventually comprised Laurel Hill Cemetery, Calvary Cemetery, the Masonic Cemetery, and Odd Fellows Cemetery. Pressure to close the complex began around the beginning of the twentieth century, and by 1941 all remains within it had been moved elsewhere, mostly to a new necropolis in Colma, California, though some were never accounted for. The land from Laurel Hill Cemetery and Calvary Cemetery was eventually used to create housing and shopping centers within the Lone Mountain neighborhood, the Masonic Cemetery land became the campus for University of San Francisco (USF), and the Odd Fellows Cemetery had maintained the columbarium and surrounding memorial park land, and the additional land was used to create the Angel ...

Doyle Drive Replacement Project
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the strait connecting San Francisco Bay and the Pacific Ocean. The structure links the U.S. city of San Francisco, California—the northern tip of the San Francisco Peninsula—to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait. It also carries pedestrian and bicycle traffic, and is designated as part of U.S. Bicycle Route 95. Being declared one of the Wonders of the Modern World by the American Society of Civil Engineers, the bridge is one of the most internationally recognized symbols of San Francisco and California. It was initially designed by engineer Joseph Strauss in 1917. The bridge was named for the Golden Gate strait, the channel that it spans. The Frommer's travel guide describes the Golden Gate Bridge as "possibly the most beautiful, certainly the most photographed, bridge in the world." At the time of its opening in 1937, it was both the long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Flora Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History Of The California Chaparral And Woodlands
Nature, in the broadest sense, is the physics, physical world or universe. "Nature" can refer to the phenomenon, phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word ...
