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 fa ...

Slope Effect
In mathematics, the slope or gradient of a line is a number that describes both the ''direction'' and the ''steepness'' of the line. Slope is often denoted by the letter ''m''; there is no clear answer to the question why the letter ''m'' is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as and it can also be found in Todhunter (1888) who wrote it as "''y'' = ''mx'' + ''c''". Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line. A line that is decreasing has a negative "rise". The line may be practical – as set by a road surveyor, or in a diagram that models a road or a roof either as a description or as a plan. The ''steepness'', incline, or grade of a line is measured by the absolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encelia Californica
''Encelia californica'' is a species of flowering plant in the family Asteraceae known by the common name California brittlebush. It is also commonly referred to as California coast sunflower and California bush sunflower. Distribution This shrub is native to southern California (U.S.) and northern Baja California (México). It is a member of the coastal sage plant community at the shoreline, and the chaparral and woodlands plant community on inland foothills in the Transverse and Peninsular Ranges.

The fruit is an achene 5 to 7 millimeters long, with no pappus. It blooms from Febru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ensenada, Baja California
Ensenada is a city in Ensenada Municipality, Baja California, situated on the Pacific Coast of Mexico. Located on the Bahía de Todos Santos, the city had a population of 279,765 in 2018, making it the third-largest city in Baja California. The city is an important international trade center and home to the Port of Ensenada, the second-busiest port in Mexico. Ensenada is a major tourist destination, owing to its warm Mediterranean climate and proximity to the Pacific Ocean, and is commonly known as ''La Cenicienta del Pacífico'' ("The Cinderella of the Pacific"). Ensenada was founded in 1882, when the small community of Rancho Ensenada de Todos Santos was made the regional capital for the northern partition of the Baja California Territory. The city grew significantly with the proliferation of mines in the surrounding mountains. While the Mexican Revolution curtailed much of Ensenada's expansion, the onset of Prohibition in the United States transformed the city into a po ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

San Luis Obispo County, California
San Luis Obispo County (), officially the County of San Luis Obispo, is a county on the Central Coast of California. As of the 2020 census, the population was 282,424. The county seat is San Luis Obispo. Junípero Serra founded the Mission San Luis Obispo de Tolosa in 1772, and San Luis Obispo grew around it. The small size of the county's communities, scattered along the beaches, coastal hills, and mountains of the Santa Lucia range, provides a wide variety of coastal and inland hill ecologies to support fishing, agriculture, and tourist activities. California Polytechnic State University has almost 20,000 students. Tourism, especially for the wineries, is popular. Grapes and other agriculture products are an important part of the economy. San Luis Obispo County is the third largest producer of wine in California, surpassed only by Sonoma and Napa counties. Strawberries are the largest agricultural crop in the county.

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. It is found along the Pacific Coast, from as far south as Los Angeles in Southern California to southern Oregon. Description California's coastal prairies are the most species-rich grassland types in North America (Stromberg et al. 2002) with at most, 26 species present per square meter. Coastal prairie is also the single most urbanized major vegetation type in the US; 24% of the habitat has been lost to pavement. Wind, salt spray, fire, and grazing are evolutionary disturbances which affected shrubs and tree growth maintaining more open grasslands. In the absence of grazing and/or fire, many areas of coastal prairie are being lost to shrub and tree encroachment. The accumulated organic matter from centuries produce a rich, dark prairie soil (''mollisol''). Coastal prairie often forms a ...

Hesperoyucca Whipplei
''Hesperoyucca whipplei'' ( syn. ''Yucca whipplei''), the chaparral yucca, our Lord's candle, Spanish bayonet, Quixote yucca or foothill yucca, is a species of flowering plant closely related to, and formerly usually included in, the genus ''Yucca''. It is native to southwest communities of North America. Description It produces a stemless cluster of long, rigid leaves which end in a sharp point. The leaves are , rarely to , long and wide, and gray-green in color. The leaf edges are finely saw-toothed. The single inflorescence grows extremely fast, and reaches tall, bearing hundreds of elliptical (bell-shaped) white to purplish flowers in diameter on a densely branched panicle up to broad, covering the upper half of the inflorescence. The fruit is a dry winged capsule, which splits open at maturity to release the seeds. The plant takes several (usually 5+) years to reach maturity and flower, doing so in April–May, at which point it usually dies. Most subspecies prod ...

Succulent
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to su ...

Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spin ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the par ...
