Wildcat Canyon Regional Park
Wildcat Canyon Regional Park is a East Bay Regional Parks District park bordering the city of Richmond in Contra Costa County in the San Francisco Bay Area of California. It includes a portion of Wildcat Canyon as well as a portion of the adjoining San Pablo Ridge, and is directly connected to the more heavily used Tilden Regional Park. History The area was inhabited by Native Americans until 1772 when a group of "Catalan volunteers" led by Pedro Fagas and Fray Juan Crespi came across the settlement while searching for trade routes north beyond the Carquinez Strait. The Spanish settled the general area and by 1840 had parceled the land for missions and cattle raising coming into conflict with the historical communal practices of the Native Americans. Juan Jose and Victor Castro were given rights to all vacant land in the area. They kept some valuable lands and gave much of the land over to municipal authorities for water usage. In 1935, the East Bay Regional Parks District a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Pablo Reservoir
The San Pablo Reservoir is an open cut terminal water storage reservoir owned and operated by the East Bay Municipal Utility District (EBMUD). It is located in the valley of San Pablo Creek, north of Orinda, California, United States, and south of El Sobrante and Richmond, east of the Berkeley Hills between San Pablo Ridge and Sobrante Ridge. San Pablo Dam The earthen San Pablo Dam, built in 1919, is located at the El Sobrante end of the reservoir, above Kennedy Grove. The reservoir has a total capacity of and a watershed of . A water tunnel runs under the hills to the west from the reservoir to a pumping plant in Kensington. The San Pablo Dam Road runs along the west side of the reservoir. EBMUD's Briones Reservoir is in the hills southeast of the San Pablo Reservoir and drains into the reservoir. Although the dam impounds the waters of San Pablo Creek, the great bulk of its water is imported via the Mokelumne Aqueduct from Pardee Reservoir located over a hundred miles t ...

Bracken Fern
Bracken (''Pteridium'') is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm). Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world. The word ''bracken'' is of Old Norse origin, related to Swedish ''bräken'' and Danish ''bregne'', both meaning fern. In the past, the genus was commonly treated as having only one species, ''Pteridium aquilinum'', but the recent trend is to subdivide it into about ten species. Like other ferns, brackens do not have seeds or fruits, but the immature fronds, known as ''fiddleheads'', are sometimes eaten, although some are thought to be carcinogenic. Description an ...

Snowberry
''Symphoricarpos'', commonly known as the snowberry, waxberry, or ghostberry, is a small genus of about 15 species of deciduous shrubs in the honeysuckle family, Caprifoliaceae. With the exception of the Chinese coralberry, '' S. sinensis'', which is indigenous to western China, all species are native to North and Central America. The name of the genus is derived from the Ancient Greek words (), meaning "to bear together", and (), meaning "fruit". It refers to the closely packed clusters of berries the species produces. Snowberry is a resilient plant able to withstand a variety of conditions. Snowberry plants are most commonly found in forests, dry or moist openings, rocky hillsides or near riverbanks and streams. They have been known to grow in a variety of soil types such as light sandy soil, medium loamy soil and heavier clay soil. Snowberry plants are also able to grow in a wide range of acidic and basic pHs and sunlight conditions. Description ''Symphoricarpos'' leaves ...

Elderberry
''Sambucus'' is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus ''Adoxa''. Description The oppositely arranged leaves are pinnate with 5–9 leaflets (or, rarely, 3 or 11). Each leaf is long, and the leaflets have serrated margins. They bear large clusters of small white or cream-colored flowers in late spring; these are followed by clusters of small black, blue-black, or red berries (rarely yellow or white).

Coyote Brush
''Baccharis pilularis'', called coyote brush (or bush), chaparral broom, and bush baccharis, is a shrub in the family Asteraceae native to California, Oregon, Washington, and Baja California. There are reports of isolated populations in New Mexico, most likely introduced. Distribution and habitat The plants are found in a variety of habitats, from coastal bluffs, oak woodlands, and grasslands, including on hillsides and in canyons, below . Coyote brush is known as a secondary pioneer plant in communities such as coastal sage scrub and chaparral. It does not regenerate under a closed shrub canopy because seedling growth is poor in the shade. Coast live oak, California bay, '' Rhus integrifolia'', and other shade producing species replace coastal sage scrub and other coyote bush-dominated areas, particularly when there has not been a wildfire or heavy grazing. In California grasslands, it comes in late and invades and increases in the absence of fire or grazing. Coyote bush inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Dogwood
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''(Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus kous ...

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] |
Alder
Alders are trees comprising the genus ''Alnus'' in the birch family Betulaceae. The genus comprises about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes. Description With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (''Betula'', another genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones. The largest species are red alder (''A. rubra'') on the west coast of North America, and black alder (''A. glutinosa''), native ...
