Gardena Willows Wetland Preserve
The Gardena Willows Wetland Preserve occupies of land owned by the City of Gardena, in Los Angeles County, California. The preserve is the last intact remnant of the former Dominguez Slough, an important vernal marsh and riparian forest with riparian zones that once covered as much as of this area, known as the South Bay region. The preserve has of wetland and of upland.Jones & Stokes Associates, Inc. (1999).A Plan for the Gardena Willows Wetland March (JSA 99-013). Sacramento, CA. The wetlands have a natural depression where water remains for such a significant time that plants and animals not adapted to water and saturated soils cannot survive. The upland, which remains dry outside of the rainy season, supports plants which thrive with these drier conditions. The slough is a part of the Dominguez Watershed, 96% of which is now covered with concrete and man-made structures. Located on the traditional lands of the Tongva, it is believed that these indigenous people were ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gardena, California
Gardena is a city located in the South Bay region of Los Angeles County, California, United States. The population was 61,027 at the 2020 census, up from 58,829 at the 2010 census. Until 2014, the U.S. census cited the City of Gardena as the place with the highest percentage of Japanese Americans in California. Gardena's Japanese American population contributes to the South Bay region of Los Angeles being home to the highest density of Japanese companies within the mainland United States. History Based on archaeological findings, the Tongva people hunted and fished in the area of today's Gardena. The Tongva Indians – also known as Gabrielino Indians – are probably descendants of those who crossed from Asia to North America around 10,000 years ago. In 1784, three years after the foundation of Los Angeles, Juan Jose Dominguez (1736–1809), a Spanish soldier who arrived in San Diego, California in 1769 with Fernando Rivera y Moncada, in recognition of his military ser ...

Clean Water Act
The Clean Water Act (CWA) is the primary federal law in the United States governing water pollution. Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation's waters; recognizing the primary responsibilities of the states in addressing pollution and providing assistance to states to do so, including funding for publicly owned treatment works for the improvement of wastewater treatment; and maintaining the integrity of wetlands.Jim Hanlon, Mike Cook, Mike Quigley, Bob Wayland"Water Quality: A Half Century of Progress."EPA Alumni Association. March 2016. The Clean Water Act was one of the United States' first and most influential modern environmental laws. Its laws and regulations are primarily administered by the U.S. Environmental Protection Agency (EPA) in coordination with state governments, though some of its provisions, such as those involving filling or dredging, are administered by the U.S. Army Corps of Engineers.

Raphanus Raphanistrum
''Raphanus raphanistrum'', also known as wild radish, white charlock or jointed charlock, is a flowering plant in the family Brassicaceae. The species is native to western Asia, Europe and parts of Northern Africa. It has been introduced into most parts of the world and is regarded as a habitat threatening invasive species in many areas, for example, Australia. It spreads rapidly and is often found growing on roadsides or in other places where the ground has been disturbed. The cultivated radish, widely used as a root vegetable, is sometimes considered to be one of its subspecies as ''Raphanus raphanistrum'' subsp. ''sativus''. Description Wild radish is an annual that grows up to 75 cm tall, variously branched to multi-stemmed, with a distinct slender taproot which does not swell like that of the cultivated radish. The stems are green and sometimes purple at the base and nodes, round in cross section and slightly ridged, and bristly-hairy all over. It has a basal rosette of pi ...

Brassica
''Brassica'' () is a genus of plants in the cabbage and mustard family (Brassicaceae). The members of the genus are informally known as cruciferous vegetables, cabbages, mustard plants, or simply brassicas. Crops from this genus are sometimes called ''cole crops''derived from the Latin ''caulis'', denoting the stem or stalk of a plant. The genus ''Brassica'' is known for its important agricultural and horticultural crops and also includes a number of weeds, both of wild taxa and escapees from cultivation. ''Brassica'' species and varieties commonly used for food include bok choy, broccoli, cauliflower, cabbage, choy sum, kohlrabi, napa cabbage, rutabaga, turnip and some seeds used in the production of canola oil and the condiment mustard. Over 30 wild species and hybrids are in cultivation, plus numerous cultivars and hybrids of cultivated origin. Most are seasonal plants ( annuals or biennials), but some are small shrubs. ''Brassica'' plants have been the subject o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castor Bean
''Ricinus communis'', the castor bean or castor oil plant, is a species of perennial flowering plant in the spurge family, Euphorbiaceae. It is the sole species in the monotypic genus, ''Ricinus'', and subtribe, Ricininae. The evolution of castor and its relation to other species are currently being studied using modern genetic tools. It reproduces with a mixed pollination system which favors selfing by geitonogamy but at the same time can be an out-crosser by anemophily (wind pollination) or entomophily (insect pollination). Its seed is the castor bean, which despite the term is not a bean (as it is not the seed of a member of the family Fabaceae). Castor is indigenous to the southeastern Mediterranean Basin, East Africa, and India, but is widespread throughout tropical regions (and widely grown elsewhere as an ornamental plant). Castor seed is the source of castor oil, which has a wide variety of uses. The seeds contain between 40% and 60% oil that is rich in triglycerides ...

Fennel
Fennel (''Foeniculum vulgare'') is a flowering plant species in the carrot family. It is a hardy, perennial herb with yellow flowers and feathery leaves. It is indigenous to the shores of the Mediterranean but has become widely naturalized in many parts of the world, especially on dry soils near the sea coast and on riverbanks. It is a highly flavorful herb used in cooking and, along with the similar-tasting anise, is one of the primary ingredients of absinthe. Florence fennel or finocchio (, , ) is a selection with a swollen, bulb-like stem base (sometimes called ''bulb fennel'') that is used as a vegetable. Description ''Foeniculum vulgare'' is a perennial herb. The stem is hollow, erect, and glaucous green, and it can grow up to tall. The leaves grow up to long; they are finely dissected, with the ultimate segments filiform (threadlike), about wide. Its leaves are similar to those of dill, but thinner. The flowers are produced in terminal compound umbels wid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Urban Runoff
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces (roads, parking lots and sidewalks) are constructed during land development. During rain, storms, and other Precipitation (meteorology), precipitation events, these surfaces (built from materials such as Asphalt concrete, asphalt and concrete), along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to Infiltration (hydrology), percolate through soil. This causes lowering of the water table (because groundwater recharge is lessened) and flooding since the amount of water that remains on the surface is greater.Water Environment Federation Alexandria, VA; an American Society of Civil ...

Pacific Tree Frog
The Pacific tree frog (''Pseudacris regilla''), also known as the Pacific chorus frog, has a range spanning the Pacific Northwest, from Northern California, Oregon, and Washington to British Columbia in Canada and extreme southern Alaska. They live from sea level to more than 10,000 feet in many types of habitats, reproducing in aquatic settings. They occur in shades of greens or browns and can change colors over periods of hours and weeks. Taxonomy The taxonomy of this frog has a complex history. First, the frog was moved from the genus '' Hyla'' to the genus '' Pseudacris'' in 1986, and ''Hyliola'' in 2016 (an elevation of the subgenus which has not been widely accepted). In 2006, Recuero ''et al.'' split the frog into three species based on DNA evidence. Recuero ''et al.'' used incorrect names for two of the three populations, but subsequent authors established that the correct name (i.e., the oldest available name) for the northern component is ''Pseudacris regilla'', for ...

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, ...

California Coastal Prairie
California coastal prairie, also known as northern coastal grassland, is a grassland plant community of California and Oregon in the temperate grasslands, savannas, and shrublands biome. This ecosystem is found along the Pacific Coast, from as far south as Los Angeles in Southern California to southern Oregon. It typically stretches as far inland as 100 km, and occurs at altitudes of 350 m or lower. Description California's coastal prairies are the most species-rich grassland types in North America, with up to 26 species present per square meter. They have been described in literature as "previously unrecognized biodiversity hotspots," and are also known to provide an array of essential services—for instance, carbon storage, water filtration, agriculture, and livestock farming. In spite of the numerous benefits associated with maintaining this ecosystem, it is considered to be one of the most threatened ecosystems in the state of California, with less than one percent of u ...
