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. History The county was formed on Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryland Farming
Dryland farming and dry farming encompass specific agricultural techniques for the non-irrigated cultivation of crops. Dryland farming is associated with drylands, areas characterized by a cool wet season (which charges the soil with virtually all the moisture that the crops will receive prior to harvest) followed by a warm dry season. They are also associated with arid conditions, areas prone to drought and those having scarce water resources. Process Dryland farming has evolved as a set of techniques and management practices used by farmers to continually adapt to the presence or lack of moisture in a given crop cycle. In marginal regions, a farmer should be financially able to survive occasional crop failures, perhaps for several years in succession. Survival as a dryland farmer requires careful husbandry of the moisture available for the crop and aggressive management of expenses to minimize losses in poor years. Dryland farming involves the constant assessing of the amo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Horned Owl
The great horned owl (''Bubo virginianus''), also known as the tiger owl (originally derived from early naturalists' description as the "winged tiger" or "tiger of the air"), or the hoot owl, is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. Its primary diet is rabbits and hares, rats and mice, and voles, although it freely hunts any animal it can overtake, including rodents and other small mammals, larger mid-sized mammals, birds, reptiles, amphibians, and invertebrates. In ornithological study, the great horned owl is often compared to the Eurasian eagle-owl (''Bubo bubo''), a closely related species, which despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the red-tailed hawk (''Buteo jamaicensis''), with which it often shares similar habitat, prey, and nesting habits by day, thus is something of a diurnal ecological equivalent.

Red-tailed Hawk
The red-tailed hawk (''Buteo jamaicensis'') is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of ''Buteo'' in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the " chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts.Preston, C. R. (2000). ''Red-tailed Hawk''. Stackpole Books. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands (from small meadows to the treed fringes of more extensive prairies), coniferous and deciduous forests, agricultur ...

Pacific Gopher Snake
The Pacific gopher snake (''Pituophis catenifer catenifer'') is a subspecies of large non-venomous colubrid snake native to the western coast of North America. Description Pacific gopher snake adults range in size from 3–7 feet (91–213 centimeters) in total length. However, most of the subspecies reach a length of 4–5 feet (122–152 cm). The hatchlings are relatively long, and they have been recorded at lengths upward of 20 inches (51 cm). The Pacific gopher snake has a base color ranging from yellow to dark brown and has a gray coloring on the sides of the body. It is a spotted snake, with the spots being dark brown. Usually there are 41 to 99 spots on the body, while the tail spots range from 14 to 33. The side of the body has 2 or 3 rows of alternating black and brown spots. A snake with keeled scales, and a narrow head that is wider than the neck, the Pacific gopher snake also displays a protruding rostral scale on the tip of the snout. The two m ...

California Tiger Salamander
The California tiger salamander (''Ambystoma californiense'') is a vulnerable amphibian native to California. It is a mole salamander. Previously considered to be a subspecies of the tiger salamander (''A. tigrinum)'', the California tiger salamander was recently designated a separate species again. The California tiger salamander distinct population segment (DPS) in Sonoma County and the Santa Barbara County DPS are listed as federally endangered, while the Central California DPS is listed as federally threatened. The Sonoma County, south San Joaquin, and the Santa Barbara County DPS have diverged from the rest of the California tiger salamander populations for over one million years, since the Pleistocene and they may warrant status as separate species. Description The California tiger salamander is a relatively large, secretive amphibian endemic to California. Adults can grow to a total length of about 7–8 inches. It has a stocky body and a broad, rounded snout. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Whipsnake

Outcrop
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Oak Woodland
An oak woodland is a plant community with a tree canopy dominated by oaks (''Quercus spp.''). In terms of canopy closure, oak woodlands are intermediate between oak savanna, which is more open, and oak forest, which is more closed. Although the community is named for the dominance of oak trees, the understory vegetation is often diverse and includes many species of grasses, sedges, forbs, ferns, shrubs, and other plants. Examples * Upper Midwestern United States oak woodlands dominated by white oak (''Quercus alba''), burr oak ('' Q. macrocarpa''), and black oak ('' Q. velutina''), with subdominant canopy species red oak (''Q. rubra'') and shagbark hickory (''Carya ovata''), with a diverse understory. The community is fire-dependent, shaped by annual, low-intensity fires. * Cork oak (''Quercus suber'') woodlands in the Mediterranean region. * Blue oak woodland is found in the inner coast ranges and the Sierra Nevada foothills in California, surrounding the Central Valley.C.
