California Species Of Special Concern
A species of special concern is a legal designation by the California Department of Fish and Wildlife for native wildlife facing significant risks. This label is applied to species that: # Have vanished from California, or for birds, no longer play their primary roles in the ecosystem # Are deemed threatened or endangered under the Federal Endangered Species Act but lack state listing # Meet the state Endangered Species Act criteria for threatened or endangered status but await formal listing # Have experienced or are currently undergoing substantial declines in population or habitat range, potentially leading to consideration for threatened or endangered status under the state Endangered Species Act if these declines persist # Possess naturally small populations that are exposed to various threats, such as habitat loss or human interference, which could result in declines meeting the criteria for threatened or endangered status under the state Endangered Species Act Definitions ...

Clemmys Marmorata
The western pond turtle (''Actinemys marmorata''), also known commonly as the Pacific pond turtle is a species of small to medium-sized turtle in the family Emydidae. The species is endemic to the western coast of the United States and Mexico, ranging from western Washington state to northern Baja California. It was formerly found in Canada (in British Columbia), but in May 2002, the Canadian Species at Risk Act listed the Pacific pond turtle as being extirpated. Taxonomy and systematics Its genus classification is mixed. ''Emys'' and '' Actinemys'' were used among published sources in 2010. It was known by several names in the Indigenous languages of its range, including kʰá:wanaka: ( Northeastern Pomo), kʰa:wana (Southern Pomo), and ʔaləšək (Lushootseed). Description The dorsal color of ''A. marmorata'' is usually dark brown or dull olive, with or without darker reticulations or streaking. The plastron is yellowish, sometimes with dark blotches in the centers of the scu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Department Of Fish And Wildlife
The California Department of Fish and Wildlife (CDFW), formerly known as the California Department of Fish and Game (CDFG), is an American state agency under the California Natural Resources Agency. The Department of Fish and Wildlife manages and protects the state's wildlife, wildflowers, trees, mushrooms, algae (kelp and seaweed) and native habitats (ecosystems). The department is responsible for regulatory enforcement and management of related recreational, commercial, scientific, and educational uses. The department also prevents illegal poaching. History The Game Act was passed in 1852 by the California State Legislature and signed into law by Governor John Bigler. The Game Act closed seasons in 12 counties for quail, partridge, mallard and wood ducks, elk, deer, and antelope. A second legislative action enacted the same year protected salmon runs. In 1854, the Legislature extended the act to include all counties of California. In 1860, protection controls were extended f ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...

San Francisco Bay
San Francisco Bay (Chochenyo language, Chochenyo: 'ommu) is a large tidal estuary in the United States, U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the cities of San Francisco, California, San Francisco, San Jose, California, San Jose, and Oakland, California, Oakland. The San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento River, Sacramento and San Joaquin River, San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Convention, Ramsar Wetland of International Importance on February 2, 2013, and the Port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high, usually with many plant stem, ...

Coastal Sage Scrub
Coastal sage scrub, also known as coastal scrub, CSS, or soft chaparral, is a low scrubland plant community of the California coastal sage and chaparral subecoregion, found in coastal California and northwestern coastal Baja California. It is within the California chaparral and woodlands ecoregion, of the Mediterranean forests, woodlands, and scrub biome. Characteristics ;Plant community Coastal sage scrub is characterized by low-growing aromatic, and drought-deciduous shrubs adapted to the semi-arid Mediterranean climate of the coastal lowlands. The community is sometimes called "soft chaparral" due to the predominance of soft, drought-deciduous leaves in contrast to the hard, waxy-cuticled leaves on sclerophyllous plants of California's chaparral communities. ;Flora Characteristic shrubs and subshrubs include: * California sagebrush (''Artemisia californica'') * Black sage (''Salvia mellifera'') * White sage (''Salvia apiana'') * California buckwheat (''Eriogonum fasci ...

Endangered Species
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, invasive species, and climate change. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environment Of California
The environment of California describes results of human habitation of the American State of California. History of environmental action California's Mediterranean climate makes vegetation susceptible to wildfires through the dry summers. Aboriginal Californians used fire to control brush, promote growth of seed-producing plants important to subsistence, and perhaps as an aid to hunting wildlife. These periodic fires kept woodland areas relatively open until 20th century laws curtailed burning in an effort to protect structures. European crops and livestock were introduced with missions along the coast from San Diego to San Francisco Bay through the late 18th and early 19th century. The California Gold Rush caused explosive population growth making San Francisco the only 19th century city west of St. Louis, Missouri.Donley, Allan, Caro, and Patton ''Atlas of California'' (1979) pp.9-19 Water soon became the limiting factor for population growth, and early laws establi ...
