Bothin Marsh
Bothin Marsh is a wetland in Marin County, California. Parts of the wetlands are in the Bothin Marsh Open Space Preserve, a regional park. Natural history The marsh, positioned at the northern arm of Richardson Bay is fed by Arroyo Corte Madera del Presidio. Bothin Marsh is situated not far from Triangle Marsh, although the latter is situated on the northern edge of the Tiburon Peninsula. It is likely that Native Americans gathered estuarine resources from Bothin Marsh, as they did from nearby Triangle Marsh. History Jo Julin was instrumental in the preservation of Bothin Marsh in the early 1970s, when developers attempted to drain the marsh in order to begin construction. Today the Bothin Marsh Open Space Preserve provides habitat for hundreds of native bird and wildlife species, including the endangered salt marsh harvest mouse and Ridgway's rail. It's also a resting stop for over 400 species of migratory birds traveling on the Pacific Flyway. ''Salicornia virginica ''Sal ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

Natural History Of Marin County, California
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the 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 φύσις by pre-So ...

Tiburon, California
Tiburon (; es, Tiburón, ) is an incorporated town in Marin County, California. It is located on the Tiburon Peninsula, which reaches south into the San Francisco Bay. It shares a ZIP code with the smaller incorporated city of Belvedere (formerly a separate island), which occupies the southwest part of the peninsula and is contiguous with Tiburon. Tiburon is bordered by Corte Madera to the north and Mill Valley to the west, but is otherwise mostly surrounded by the bay. Besides Belvedere and Tiburon, much of the peninsula is unincorporated, including portions of the north side and the communities of Strawberry and Paradise Cay. The population of Tiburon was 9,146 at the 2020 census and has 6,600 registered voters. Belvedere and Tiburon share a post office, library and recreation agency. The city's name derives from the Spanish word ''tiburón'', which means "shark". The name was first given to the peninsula on which the city is situated, and probably inspired by the prevale ...

Landforms Of Marin County, California
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Marshes Of California
A marsh is a wetland that is dominated by Herbaceous plant, herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by Poaceae, grasses, Juncaceae, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a Carr (landform), carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of Invertebrate, invertebrates, fish, Amphibian, amphibians, Anseriformes, waterfowl and Aquatic mammal, aquatic mammals.

Salicornia Virginica
''Salicornia virginica'' (American glasswort, pickleweed) is a halophytic perennial dicot which grows in various zones of intertidal salt marshes and can be found in alkaline flats. It is native to various regions of the Northern Hemisphere including both coasts of North America from Canada to Mexico. The plant is one of the ''Salicornia'' species being tested as biofuel Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels, such as oil. According to the United States Energy Information Administration (E ... crop as its seeds are composed of 32% oil, and being a halophyte, it can be irrigated with salt water.

Ridgway's Rail
Ridgway's rail (''Rallus obsoletus'') is a near-threatened species of bird. It is found principally in California's San Francisco Bay to southern Baja California. A member of the rail family, Rallidae, it is a chicken-sized bird that rarely flies. This species is closely related to the clapper rail, and until recently was considered a subspecies. It has a long, downward curving bill and is grayish brown with a pale chestnut breast and conspicuous whitish rump patch. The population levels of Ridgway's rail are precariously low due to destruction of its coastal and estuarine marshland habitat by prior land development and shoreline fill. It has year-long, circadian activity and is most vocal nocturnally and crepuscularly. The Ridgway's rail pertains to the Rallidae family within order Gruiformes. The California subspecies naturally exists in tidal salt and brackish marshes. These ecosystems are subjected to freely flowing daily tidal flows, a sustainable amount of prey food supp ...

Salt Marsh Harvest Mouse
The salt marsh harvest mouse (''Reithrodontomys raviventris''), also known as the red-bellied harvest mouse, is an endangered rodent endemic to the San Francisco Bay Area salt marshes in California. The two distinct subspecies are both endangered and listed together on federal and state endangered-species lists. The northern subspecies (''R. r. halicoetes'') is lighter in color and inhabits the northern marshes of the bay, and the southern subspecies (''R. r. raviventris'') lives in the East and South Bay marshes. They are both quite similar in appearance to their congener species, the Western harvest mouse, ''R. megalotis'', to which they are not closely related. Genetic studies of the northern subspecies have revealed that the salt marsh harvest mouse is most closely related to the plains harvest mouse, ''R. montanus'', which occurs now in the Midwest. Its endangered designation is due to its limited range, historic decline in population and continuing threat of habitat loss du ...

Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
