Mountain Ranges Of Contra Costa County, California
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Alhambra Creek
Alhambra Creek is a stream in Contra Costa County, in the East Bay region of the San Francisco Bay Area in northern California. Geography The creek drains into the Carquinez Strait at Martinez, via the historical Arroyo del Hambre. Alhambra Creek and its valley take their name from Cañada del Hambre, Spanish for "valley of hunger", apparently because of some unknown incident involving starving Spanish soldiers. The name appears on ''diseños'' repeatedly and appears on an 1842 land grant, Rancho Cañada del Hambre y Las Bolsas. Although technically Alhambra Creek only refers to the upper section of , and the United States Board on Geographic Names in 1943 confirmed Arroyo del Hambre as the name for the lower creek, Mrs. John Strentzel, John Muir's' mother-in-law, did not like the name and renamed the lower creek also as Alhambra Creek. Currently the entire creek is commonly called the Alhambra Creek, and Arroyo del Hambre Creek and Franklin Creek are considered its two trib ...

It flows westerly through the towns of Pinole and El Sobrante, to its river mouth at the Chelsea Wetlands in Hercules on San Pablo Bay. Its mouth is east of Point Pinole. History The name Pinole is from the Spanish term for "parched corn", which the Mexicans ground for eating. In 1823, a Mexican land grant for that included Pinole Creek was granted to Don Ignacio Martinez, a Commandant of the San Francisco Presidio. The land grant was initially known as ''El Rancho de La Nuestra Sonora de Merced'', and later renamed Rancho El Pinole.

Riparian Zone
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] |
Chaparral
Chaparral ( ) is a shrubland plant community and geographical feature found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires. Chaparral features summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of California's wildland vegetation and contains 20% of its plant species. The name comes from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Oak Woodland
California oak woodland is a plant community found throughout the California chaparral and woodlands ecoregion of California in the United States and northwestern Baja California in Mexico. Oak woodland is widespread at lower elevations in coastal California; in interior valleys of the Coast Ranges, Transverse Ranges and Peninsular Ranges; and in a ring around the California Central Valley grasslands. The dominant trees are oaks, interspersed with other broadleaf and coniferous trees, with an understory of grasses, herbs, geophytes, and California native plants. Oak savannas occur where the oaks are more widely spaced due a combination of lack of available moisture, and low-intensity frequent fires. The oak woodlands of Southern California and coastal Northern California are dominated by coast live oak (''Quercus agrifolia''), but also include valley oak ( ''Q. lobata''), California black oak ( ''Q. kelloggii''), canyon live oak ( ''Q. chrysolepis''), and other California oa ...
