Soledad Valley
Soledad Valley is a coastal valley in San Diego County, California at the northern end of the city of San Diego. Mention of the valley was made as early as 1850 in association with the occurrence of ''Pinus torreyana'' at the mouth of the lagoon.

Pinus Torreyana
The Torrey pine (''Pinus torreyana'') is a rare pine species in California, United States. It is a critically endangered species growing only in coastal San Diego County, and on Santa Rosa Island, offshore from Santa Barbara in Santa Barbara County. The Torrey pine is endemic to the California coastal sage and chaparral ecoregion. Taxonomy The species epithet ''torreyana'' is named for John Torrey, an American botanist, after whom the coniferous genus ''Torreya'' is also named. Description ''Pinus torreyana'' is a broad, open-crowned pine tree growing to tall in the wild, with long leaves ('needles') in groups of five. The cones are stout and heavy, typically long and broad, and contain large, hard-shelled, but edible, pine nuts. Like all pines, its needles are clustered into ' fascicles' that have a particular number of needles for each pine species; in the Torrey pine there are five needles in each fascicle. Like all pines, it has strobili, structures that function as a ... [...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] |

Del Mar, California
Del Mar (; Spanish for "Of the Sea") is a beach town in San Diego County, California, located on the coast of the Pacific Ocean. Established in 1885 as a seaside resort, the city incorporated in 1959. The Del Mar Horse Races are hosted on the Del Mar racetrack every summer. In 1885, Colonel Jacob Taylor purchased from Enoch Talbert, with visions of building a seaside resort for the rich and famous. The United States Navy operated a Naval Auxiliary Air Facility for blimps at Del Mar during World War II. The population was 3,954 at the 2020 census, down from 4,161 at the 2010 census. The town has a wealthy population along the coast and the bluffs above the ocean. However, these properties are very vulnerable to climate change, which has caused sea level rise and subsequent coastal erosion; already transportation infrastructure has been under threat. The city has a climate change adaptation plan which notably excludes the option of a managed retreat, even though such a strateg ...

Valleys Of San Diego County, California
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. For ...
