Valley Oak
''Quercus lobata'', commonly called the valley oak or roble, grows into the largest of California oaks. It is endemic to California, growing in interior valleys and foothills from Siskiyou County to San Diego County. Mature specimens may attain an age of up to 600 years. This deciduous oak requires year-round access to groundwater. Its thick, ridged bark is characteristic and resembles alligator hide. The valley oak's deeply lobed leaves assist in identification. Description The valley oak may surpass in height, with a sturdy trunk possibly exceeding in diameter. The "Henley Oak", in Covelo, California, is the tallest known valley oak, at . The branches have an irregular, spreading and arching appearance that produce a profound leafless silhouette in the clear winter sky. During autumn, the leaves turn a yellow to light orange color but become brown later in the season. In advancing age, the branches assume a drooping characteristic. The tree's pewter-colored rippled bark a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

White Oak
The genus ''Quercus'' contains about 500 species, some of which are listed here. The genus, as is the case with many large genera, is divided into subgenera and sections. Traditionally, the genus ''Quercus'' was divided into the two subgenera ''Cyclobalanopsis'', the ring-cupped oaks, and ''Quercus'', which included all the other sections. However, a comprehensive revision in 2017 identified different relationships. Now the genus is commonly divided into a subgenus ''Quercus'' and a sugenus ''Cerris'', with ''Cyclobalanopsis'' included in the latter. The sections of subgenus ''Quercus'' are mostly native to the New World, with the notable exception of the white oaks of sect. ''Quercus'' and the endemic Quercus pontica. In contrast, the sections of the subgenus ''Cerris'' are exclusively native to the Old World. Legend Species with evergreen foliage ("live oaks") are tagged '#'. Species in the genus have been recategorized between deciduous and evergreen on numerous occasions, alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interior Live Oak
''Quercus wislizeni'', known by the common name interior live oak, is an evergreen oak, highly variable and often shrubby, found in many areas of California in the United States continuing south into northern Baja California in Mexico. It generally occurs in foothills, being most abundant in the lower elevations of the Sierra Nevada, but also widespread in the Pacific Coast Ranges—where since 1980 it has been known as a separate species ''Quercus parvula''—and the San Gabriel Mountains. It was named for its collector, Friedrich Adolph Wislizenus (1810–1889). Description It is a large shrub or tree growing to tall, although where it is common in the low-elevation Sierra Nevada foothills it seldom exceeds . The dark-green leaves—appearing grayish from a distance—are usually small, long, thick, and often spiny-toothed at higher elevations, particularly on young trees. The male flowers are on catkins, the female flowers in leaf axils. The acorns are long, and mature the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Live Oak
''Quercus agrifolia'', the California live oak, or coast live oak, is a highly variable, often evergreen oak tree, a type of live oak, native to the California Floristic Province. It may be shrubby, depending on age and growing location, but is generally a medium-sized tree. It grows west of the Sierra Nevada mountain range from Mendocino County, California, south to northern Baja California in Mexico. It is classified in the red oak section of oaks (''Quercus'' sect. ''Lobatae''). This species is commonly sympatric with canyon live oak (''Q. chrysolepis''), and the two may be hard to distinguish because their spinose leaves are superficially similar. Description Coast live oak typically has a much-branched trunk and reaches a mature height of . Some specimens may attain an age exceeding 1,000 years. Examples of this include the Grand Oak of Cherry Valley, California, the Encino Oak Tree, which died in the 1990s (part of the stump has been preserved) and the Pechanga Gre ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Foothill Woodland
Foothill woodland is a California vegetation type characterized by an overstory of broadleaf and coniferous trees, generally found in areas of higher elevations and more precipitation than grasslands and oak savannah, and at lower elevations and less precipitation than mixed coniferous. Sierra Nevada range In the Sierra Nevada range, it is found on western slopes at elevations of in the northern part of the range, in the central part, and in the southern part.Sierra Nevada Wildflowers, Karen Wiese, 2nd ed, 2013, p. 12-13 Annual precipitation in its range is , with little precipitation in the summer. Growing season is 6–10 months. Temperatures range in the summer, and in winter. In the Sierra Nevada range, it is characterized by a dominant overstory of Foothill Pine ('' Pinus sabiniana''), Blue Oak (''Quercus douglasii''), Interior Live Oak (''Quercus chrysolepis''), California Black Oak (''Quercus kelloggii''), California Buckeye (''Aesculus californica''), and understory p ...

Riparian
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Konkow Language
The Konkow language, also known as Northwest Maidu (also ''Concow-Maidu'', or ' in the language itself) is a part of the Maiduan language group. It is spoken in California. It is severely endangered, with three remaining elders who learned to speak it as a first language, one of whom is deaf. As part of an effort to regain official recognition as a federally recognized tribe, an effort to provide language instruction amongst the descendants of the original tribe and affiliated family members has begun. In the name , means "meadow", with the additional creating the adjective form of the word. Hence, would be spoken by the ("tribe"). Dialects One source supports the claim that Northwest Maidu had at least nine dialects, designated today according to the locality in which each was spoken. These dialects were: Otaki, Mikchopdo, Cherokee, Eskeni, Pulga, Nemsu, Feather Falls, Challenge, and Bidwell Bar. Lexica of each remain scant. In addition, there may have been many family ...

Maidu
The Maidu are a Native American people of northern California. They reside in the central Sierra Nevada, in the watershed area of the Feather and American rivers. They also reside in Humbug Valley. In Maiduan languages, ''Maidu'' means "man." Local division The Maidu people are geographically dispersed into many subgroups or bands who live among and identify with separate valleys, foothills, and mountains in Northeastern Central California. There are three subcategories of Maidu: * The Nisenan or Southern Maidu occupied the whole of the American, Bear, and Yuba River drainages. They live in lands that were previously home to the Martis. * The Northeastern or Mountain Maidu, also known as Yamani Maidu, lived on the upper North and Middle forks of the Feather River. * The Konkow (Koyom'kawi/Concow) occupied a valley between present-day Cherokee, and Pulga, along the north fork of the Feather River and its tributaries. The Mechupda live in the area of Chico, California. Populati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spaniard
Spaniards, or Spanish people, are a Romance ethnic group native to Spain. Within Spain, there are a number of national and regional ethnic identities that reflect the country's complex history, including a number of different languages, both indigenous and local linguistic descendants of the Roman-imposed Latin language, of which Spanish is the largest and the only one that is official throughout the whole country. Commonly spoken regional languages include, most notably, the sole surviving indigenous language of Iberia, Basque, as well as other Latin-descended Romance languages like Spanish itself, Catalan and Galician. Many populations outside Spain have ancestors who emigrated from Spain and share elements of a Hispanic culture. The most notable of these comprise Hispanic America in the Western Hemisphere. The Roman Republic conquered Iberia during the 2nd and 1st centuries BC. Hispania, the name given to Iberia by the Romans as a province of their Empire, became highly accu ...

History Of California Before 1900
Human history in California began when indigenous Americans first arrived some 13,000 years ago. Coastal exploration by the Spanish began in the 16th century, with further European settlement along the coast and in the inland valleys following in the 18th century. California was part of New Spain until that kingdom dissolved in 1821, becoming part of Mexico until the Mexican–American War (1846–1848), when it was ceded to the United States under the terms of the 1848 Treaty of Guadalupe Hidalgo. The same year, the California Gold Rush began, triggering intensified U.S. westward expansion. California joined the Union as a free state via the Compromise of 1850. By the end of the 19th century, California was still largely rural and agricultural, with a population of about 1.4 million. Pre-Columbian history (~13,000 BC-1530 AD) The most commonly accepted model of migration to the New World is that people from Asia crossed the Bering land bridge to the Americas some 16,500 y ...
