Zayante Creek
Zayante Creek (Ohlone: ''Sayant'') is a stream within the San Lorenzo River watershed in Santa Cruz County, California, United States. The U.S. government has designated Zayante Creek as impaired with respect to sediment. Lompico Creek, a tributary of Zayante Creek, is listed for impairment by pathogens. In the period 1998 to 2000 a restoration project was conducted for this stream to improve anadromous fish passage, rearing and Spawn (biology), spawning. There has been a permanent U.S. Geological Survey stream gauge, gauging station on Zayante Creek which has operated since the year 1959; the mean altitude of the Zayante Basin, carved within the western slopes of the Santa Cruz Mountains, is . Significant tributaries to Zayante Creek are Lompico Creek and Bean Creek (Zayante Creek), Bean Creek. Geology Soils formations along the mainstem (hydrology), mainstem of Zayante Creek by ascending altitude are: Monterey Formation, Zayante Formation, Vaqueros sandstone, Vaqueros Sand ...

Awaswas Language
Awaswas, or Santa Cruz, is one of eight Ohlone languages. It was historically spoken by the Awaswas people, an indigenous peoples of California, indigenous people of California. The last speaker of Awaswas died in the 19th century, and the language has been extinct ever since. Linguists originally called the language Santa Cruz after the mission in the area, but it was renamed to Awaswas as part of a move in the late 1960s and early 1970s by graduate students at the University of California Berkeley to use native names for the Ohlone languages. 'Awaswas' is derived from the term , meaning 'north-people from there'. History The Awaswas lived in the Santa Cruz Mountains and along the coast of present-day Santa Cruz County, California, Santa Cruz County from present-day Davenport, California, Davenport to Aptos, California, Aptos. Awaswas became the main language spoken at the Mission Santa Cruz. However, there is evidence that this grouping was more geographic than linguisti ...

Spawn (biology)
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and amphibious animals reproduce through spawning. These include the following groups: * Bony fishes * Crustaceans (such as crabs, shrimps, etc.) *Mollusks (such as oysters, octopus, squid) *Echinoderms (such as sea urchins, sea stars, sea cucumbers, etc.) * Amphibians (such as frogs, toads, salamanders, newts) * Aquatic insects (such as dragonflies, mayflies, mosquitoes) *Coral, which are living colonies of tiny, aquatic organisms—not plants, as they are sometimes perceived to be. Corals, while appearing sedentary or botanical by nature, actually spawn by releasing clouds of sperm and egg cells into the water column, where the two mix. As a general rule, aquatic or semiaquatic reptiles, birds, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Santa Cruz County, California
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Townsend's Warbler
Townsend's warbler (''Setophaga townsendi'') is a small songbird of the New World warbler family. Taxonomy Townsend's warbler was species description, formally described in 1837 by the American naturalist John Kirk Townsend under the binomial name ''Sylvia townsendi''. The type locality (biology), type locality is Fort Vancouver on the Columbia River in the state of Washington. After the merger of the genera ''Dendroica'' and ''Setophaga'', Townsend's warbler is now placed in the genus ''Setophaga'' that was introduced by the English naturalist William Swainson in 1827. The species is monotypic: no subspecies are recognised. Description Townsend's warbler has a yellow face with a black stripe across its cheeks extending into an ear patch, a thin pointed bill, two white wing bars, olive upperparts with black streaks on their backs and flanks, and a white belly. Adult males have a black cap, black throat and yellow lower breast; females have a dark cap and a yellow throat. Immature ...

Avafauna
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have furthe ...

Endangered Arthropod
In July 2016, the International Union for Conservation of Nature (IUCN) listed 616 endangered arthropod species. Of all evaluated arthropod, 6.5% species are listed as endangered. The IUCN also lists 27 arthropod subspecies as endangered. No subpopulations of arthropods have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered arthropods are listed separately. There are 1010 arthropod species which are endangered or critically endangered. Additionally 2875 arthropod species (30% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime Coast Range Ponderosa Pine Forest
The maritime coast range ponderosa pine forests, also known as ponderosa sand parklands and ponderosa pine sandhills, are a rare temperate forest community consisting of open stands of a disjunct population of ponderosa pine growing on sandy soils in the Santa Cruz Mountains of north central coastal California. Limited to approximately , the only two known occurrences of this type are near the towns of Ben Lomond and Bonny Doon in Santa Cruz County. Description This forest type is restricted to very sandy Zayante soils that are isolated pockets of decomposing sandstone from the Miocene terraces of the coastal range, distinct from the volcanically formed rocks which make up most of the Santa Cruz Range. These soils are deemed to be relicts of once larger expanses found when this region was geologically even younger, and hence had more evidence of the sandstone erosion of the ancient uplifted ocean floor. Estimated to originally cover , 40% of this type has been lost, mostly to san ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lompico Sandstone
The Lompico Sandstone is a sedimentary rock formation of lower to middle Miocene age. It overlies the Salinian basement rocks of Santa Cruz County, California. It interfingers with and is overlain by the Miocene Monterey Formation. These are in turn overlain by the mid to upper Miocene Santa Margarita Sandstone which is in turn overlain by the upper Miocene Santa Cruz Mudstone. Hydrological importance There are numerous occurrences of this rock strata including coastal mountain ranges from Northern to Southern California. In the coastal range of Santa Cruz County the formation has been documented in the Zayante Creek watershed. The formation is often associated with groundwater recharge areas.David C. Estrada, John Ricker, Robert Aston. 1979.

Vaqueros Sandstone
The Vaqueros Formation is a sedimentary geologic unit primarily of Upper Oligocene and Lower Miocene age, which is widespread on the California coast and coastal ranges in approximately the southern half of the state. It is predominantly a medium-grained sandstone unit, deposited in a shallow marine environment. Because of its high porosity and nearness to petroleum source rocks, in many places it is an oil-bearing unit, wherever it has been configured into structural or stratigraphic traps by folding and faulting. Being resistant to erosion, it forms dramatic outcrops in the coastal mountains. Its color ranges from grayish-green to light gray when freshly broken, and it weathers to a light brown or buff color. Type locality and deposition environment The type locality of the Vaqueros is from Vaqueros Canyon in the Santa Lucia Mountains, about eight miles southwest of Greenfield. The formation was first described by Homer Hamlin in 1904, as part of a report on the water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainstem (hydrology)
In hydrology, a main stem or mainstem (also known as a trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". The mainstem extends all the way from one specific headwater to the outlet of the river, although there are multiple ways to determine which headwater (or first-order tributary) is the source of the main stem. Water enters the main stem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton sy ...
