Sunol Regional Wilderness
The Sunol Regional Wilderness is a regional park in Alameda County, the eastern San Francisco Bay Area, Northern California. It is located near the town of Sunol, south of Pleasanton and east of Fremont. The park was established in 1962, and is administered by the East Bay Regional Park District. The park is subject to either closure or fire restriction during the wildfire season from June through October. Natural history The park is in the inner California Coast Ranges. It originally was inhabited by Native Americans, and was subsequently primarily ranch land, with chaparral, oak woodland, and grassland habitats. Grazing rights within the park are still leased, so cattle may be encountered. Flora Common trees in the park include Coast live oak (''Quercus agrifolia''), Valley oak (''Quercus lobata''), Blue oak (''Quercus douglasii''), Mexican elderberry (''Sambucus cerulea''), Pacific Madrone (''Arbutus menziesii'') and Gray pine (''Pinus sabiniana'').

Alameda County, California
Alameda County ( ) is a county located in the U.S. state of California. As of the 2020 census, the population was 1,682,353, making it the 7th-most populous county in the state and 21st most populous nationally. The county seat is Oakland. Alameda County is in the San Francisco Bay Area, occupying much of the East Bay region. The Spanish word ''alameda'' means either "a grove of poplars...or a tree lined street." The name was originally used to describe the Arroyo de la Alameda. The willow and sycamore trees along the banks of the river reminded the early Spanish explorers of a road lined with trees. Although a strict translation to English might be "Poplar Grove Creek," the name of the principal stream that flows through the county is now simply " Alameda Creek." Alameda County is part of the San Francisco–Oakland–Berkeley, CA Metropolitan Statistical Area, and the San Jose–San Francisco–Oakland, CA Combined Statistical Area.

Ranunculus Californicus In Sunol Regional Wilderness
''Ranunculus'' is a large genus of about almost 1700 to more than 1800 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots. The genus is distributed in Europe, North America and South America. The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup ''Ranunculus repens'', which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup ''Ranunculus bulbosus'' and the much taller meadow buttercup ''Ranunculus acris''. In ornamental gardens, all three are often regarded as weeds. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds. The water crowfoots (''Ranunculus'' subgenus ''Batrachium''), which grow in still or running water, are sometimes trea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Collinsia
''Collinsia'' is a genus of about 20 species of annual flowering plants, consisting of the blue eyed Marys and the Chinese houses. It was traditionally placed in the snapdragon family Scrophulariaceae, but following recent research in molecular genetics, it has now been placed in a much enlarged family Plantaginaceae. The genus is endemic to North America, and is named in honor of Zacchaeus Collins, a Philadelphia botanist of the late eighteenth/early nineteenth century. Many of the 20 species may be found in California. Two species, ''Collinsia parviflora'' (smallflower blue eyed Mary) and ''Collinsia violacea'' (violet blue eyed Mary), had medicinal uses among American Indian peoples. Species include: *''Collinsia antonina'' *''Collinsia bartsiifolia'' *'' Collinsia callosa'' *'' Collinsia childii'' *''Collinsia concolor'' *''Collinsia corymbosa'' *''Collinsia grandiflora'' *''Collinsia greenei'' *''Collinsia heterophylla'' *''Collinsia linearis'' *''Collinsia multicolor' ...

Willow
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alnus Rhombifolia
''Alnus rhombifolia'', the white alder, is an alder tree native to western North America, from British Columbia and Washington east to western Montana, southeast to the Sierra Nevada, and south through the Peninsular Ranges and Colorado Desert oases in Southern California.

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] |
