Pine Lake (San Francisco)
Pine Lake, previously known as Laguna Puerca or Pig Lake, is a freshwater lake in Pine Lake Park in the southwest corner of San Francisco. The lake is fed from the same aquifer as nearby Lake Merced. History The surrounding area and lake, then known as Laguna Puerca or Pig Lake, were purchased by the Greene family following their move from Maine to San Francisco in 1847. The lake was purchased by the City of San Francisco in the five years following the nearby Sigmund Stern Recreation Grove. Ecology The lake is fed by an underground spring, which also feeds nearby Lake Merced. It is surrounded by willows, Schoenoplectus acutus, tules, and aquatic plants. Migratory birds along the Pacific Flyway stop to feed, rest, or inhabit the surrounding area. The only natural freshwater lakes in San Francisco are Pine Lake, Lake Merced, and Mountain Lake Park, Mountain Lake.

Pine Lake Park (San Francisco)
Pine Lake Park is a park in the southwest corner of San Francisco, California which encompasses Pine Lake (San Francisco), Pine Lake. History Following their move from Maine to San Francisco in 1847, the Greene family purchased a large property which included Stern Grove and Pine Lake (San Francisco), Pine Lake. In 1887, a lawsuit forced the family to give up most of the property and allowed them to retain only the portion which today comprises the park and adjacent Sigmund Stern Recreation Grove. The family planted the Eucalyptus, eucalyptus trees that continue to surround the lake. The land and lake was purchased by the City of San Francisco in the five years following the opening of the adjoining Sigmund Stern Recreation Grove in 1932. Geography Pine Lark Park is located in the southwest corner of San Francisco and occupies .

Pacific Flyway
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites. Any given bird species travels roughly the same route every year, at almost the same time. Ornithologists and birdwatchers can often predict to the day when a particular species will show up in their area. Notable locations Along the Pacific Flyway, there are many key rest stops where birds of many species gather, sometimes in the millions, to feed and regain their strength before continuing. Some species may remain in these rest stops for the entire season, but most stay a few days before moving on. :''Notable locations include:'' * Boundary Bay, British Columbia, has been listed as an Important Bird Area by the Canadian government in recognition of its value to migratory bi ...

It occupies in the southeast corner of the state, but because it is shallow it only holds about of water. Tulare Lake in the San Joaquin Valley was larger, at approximately , until it was drained during the later years of the nineteenth century. In terms of volume, the largest lake on the list is Lake Tahoe, located on the California–Nevada border. It holds roughly of water. It is also the largest freshwater lake by area, at , and the deepest lake, with a maximum depth of .

Landmarks In San Francisco
A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern use, the term can also be applied to smaller structures or features, that have become local or national symbols. Etymology In old English the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc.". Starting from approx. 1560, this understanding of landmark was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by explorers and others to find their way back or through an area. For example, the Table Mountain near Cape Town, South Africa is used as the landmark to help sailors to navigate around southern tip of Africa during the Age of Exploration. Artificial structures are also sometimes built t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Lake Park
Mountain Lake Park is a San Francisco park in the Richmond District neighborhood, located north of the intersection of Lake and Funston. It was designed by engineer William Hammond Hall in the late 19th century, circa 1875. Hall also designed Golden Gate Park and was significantly influenced by Frederick Law Olmsted. History Spanish explorer Juan Bautista de Anza ended his second northward expedition at the lake, stopping for two days in 1776. While here he located a site for the Spanish presidio that was later built. A plaque was placed in September 1957 near the point where he stayed. Fill taken from the cut to build the MacArthur Tunnel was dumped near Mountain Lake during the construction of the Funston Avenue approach to the Golden Gate Bridge in 1939. The fill was used to compress marshy lands but also reduced the size of the lake. The US Army imposed conditions on the approval of construction permits through the Presidio, including requiring the drainage of runoff fro ...

Aquatic Plant
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...

Schoenoplectus Acutus
''Schoenoplectus acutus'' ( syn. ''Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris'' subsp. ''acutus''), called tule , common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America. The common name derives from the Nāhuatl word ''tōllin'' , and it was first applied by the early settlers from New Spain who recognized the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City. Tules once lined the shores of Tulare Lake in California, formerly the largest freshwater lake in the western United States. It was drained by land speculators in the 20th century. The expression "out in the tules" is still common, deriving from the dialect of old Californian families and meaning "where no one would want to live", with a touch of irony. The phrase is comparable to "out in the boondocks". ''Schoenoplectus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willow
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
