Wildwood Canyon
Wildwood Canyon is a canyon and California state park in the eastern foothills of the San Bernardino Mountains, within San Bernardino County, southern California. It is located near the city of Yucaipa, in the Inland Empire region. It is surrounded by the San Bernardino National Forest on the eastern and northern sides. History The indigenous Cahuilla were traditionally active in the area of Wildwood Canyon, as were the Serrano and Tongva. The area near Yucaipa was known as a crossroads for traveling indigenous people. Historic buildings remain in the park from the 1930s Hi Up House ranch and 1940s Hunt Ranch eras. After a flood threatened developers' housing subdivision plans, the California Department of Parks and Recreation acquired in the canyon. In May 2003 a park dedication ceremony was held at Wildwood Canyon. Wildwood Canyon State Park Wildwood Canyon State Park is currently open only for day use, from sunrise to sunset. The primary activities are horseback riding, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towhee
A towhee is any one of a number of species of birds in the genus '' Pipilo'' or '' Melozone'' within the family Passerellidae (which also includes American sparrows, and juncos). Towhees typically have longer tails than other Passerellidae. Most species tend to avoid humans, so they are not well known, though the eastern towhee ''P. erythrophthalmus'' is bolder. This species, and some others, may be seen in urban parks and gardens. There has been considerable debate over the taxonomy of the towhees in recent years. Two species complexes have been identified, the rufous-sided complex (involving ''Pipilo erythrophthalmus'', ''P. maculatus'', ''P. socorroensis'', ''P. ocai'' and ''P. chlorurus''), and the brown towhee complex (involving ''Melozone crissalis'', ''M. fuscus'', ''M. aberti'' and ''M. albicollis''). The distinction of species within these is uncertain and opinions have differed over the years. Modern authorities distinguish all four species in the brown towhee complex ...

Quercus Berberidifolia
''Quercus berberidifolia'', the California scrub oak, is a small evergreen or semi-evergreen shrubby oak in the white oak section of ''Quercus''. It is a native of the scrubby hills of California, and is a common member of chaparral ecosystems. Description ''Quercus berberidifolia'' grows to tall, rarely to , and has sharply toothed, dull green leaves which are long and broad, leathery on their top surfaces and somewhat hairy underneath. The solitary or paired brown acorns are long and broad, and pointed or egg-shaped with thin caps when mature; they mature in about 6–8 months after pollination. In cooler, more exposed areas, scrub oak is usually a small, compact shrub, but in warm or sheltered areas the plant can spread out and grow several meters high. The epithet ''berberidifolia'' means "barberry-leaved," referring to the spiny leaf margins characteristic of ''Q. berberidifolia'' as well as of several species of ''Berberis.'' Other species The species is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adenostoma Fasciculatum
''Adenostoma fasciculatum'', commonly known as chamise or greasewood, is a flowering plant native to California and Baja California. This shrub is one of the most widespread plants of the California chaparral ecoregion. Chamise produces a specialized lignotuber underground and at the base of the stem, known as a burl, that allow it to resprout after fire has off burned its stems. It is noted for its greasy, resinous foliage, and its status as one of California's most iconic chaparral shrubs.Rundel, P. W. (2018)California chaparral and its global significance. In ''Valuing Chaparral''(pp. 7). Springer, Cham. Description Morphology It is a shrub with long, arching stems of brown to gray bark, and is usually less than 4 meters high. It is diffusely branched and spreading in habit, with some forms prostrate. The stems are slender, numerous, and erect, and generally lack permanent branches. The young stems have reddish bark, and become gray with exfoliating bark in later age. The ... [...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 fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Diego Pocket Mouse
The San Diego pocket mouse (''Chaetodipus fallax'') is a rodent species in the family Heteromyidae. It occupies the northern region of Baja California near San Diego extending into Mexico. Description The San Diego pocket mouse occupies the northern region of Baja California near San Diego extending into Mexico. This moderately sized mouse is characterized by dark brown fur covering the top of its body with white fur on its underside. Its length ranges from 170 to 200 mm and its weight is approximately 17–22 g. The San Diego pocket mouse is a homoeothermic endotherm with both hypsodont and lophodont teeth. Similar species include ''C. californicus'', which shares the same habitat. Reproduction The San Diego pocket mouse is often a solitary animal, which makes it difficult to study its reproductive history. Many individuals mate in the spring, but others have been known to mate throughout the year. Reproduction occurs 1–3 times a year. There is significant eviden ...

Wildlife Corridor
A wildlife corridor, habitat corridor, or green corridor is an area of habitat (ecology), habitat connecting wildlife populations separated by human activities or structures (such as roads, development, or logging). This allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding and reduced genetic diversity (via genetic drift) that often occur within isolated populations. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to Disturbance (ecology), random events (such as fires or disease). This may potentially moderate some of the worst effects of habitat fragmentation, wherein urbanization can split up habitat areas, causing animals to lose both their natural habitat and the ability to move between regions to use all of the resources they need to survive. Habitat fragmentation due to Human development theory, human development is an ever-increasing threat to biodive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cougar
The cougar (''Puma concolor'') is a large cat native to the Americas. Its range spans from the Canadian Yukon to the southern Andes in South America and is the most widespread of any large wild terrestrial mammal in the Western Hemisphere. It is an adaptable, generalist species, occurring in most American habitat types. This wide range has brought it many common names, including puma, mountain lion, catamount and panther (for the Florida sub-population). It is the second-largest cat in the New World, after the jaguar (''Panthera onca''). Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. Despite its size, the cougar is more closely related to smaller felines, including the domestic cat (''Felis catus'') than to any species of the subfamily Pantherinae. The cougar is an ambush predator that pursues a wide variety of prey. Primary food sources are ungulates, particularly deer, but it a ...

Gray Fox
The gray fox (''Urocyon cinereoargenteus''), or grey fox, is an omnivorous mammal of the family Canidae, widespread throughout North America and Central America. This species and its only congener (biology), congener, the diminutive island fox (''Urocyon littoralis'') of the California Channel Islands of California, Channel Islands, are the only living members of the genus ''Urocyon'', which is considered to be genetically Basal (phylogenetics), basal to all other living canids. Its Specific name (zoology), species name ''cinereoargenteus'' means ":wikt:cinereus, ashen silver". It was once the most common fox in the eastern United States, and though still found there, human advancement and deforestation allowed the red fox to become the predominant Canidae, fox-like canid. Despite this post-colonial competition, the gray fox has been able to thrive in urban and suburban environments, one of the best examples being South Florida, southern Florida. The Pacific States and Great Lak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Black Bear
The American black bear (''Ursus americanus''), also called simply a black bear or sometimes a baribal, is a medium-sized bear endemic to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but will leave forests in search of food, and are sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species, due to its widespread distribution and a large population estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of only two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution Despite living in North America, American black bears are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bobcat
The bobcat (''Lynx rufus''), also known as the red lynx, is a medium-sized cat native to North America. It ranges from southern Canada through most of the contiguous United States to Oaxaca in Mexico. It is listed as Least Concern on the IUCN Red List since 2002, due to its wide distribution and large population. Although it has been hunted extensively both for sport and fur, populations have proven stable, though declining in some areas. It has distinctive black bars on its forelegs and a black-tipped, stubby (or "bobbed") tail, from which it derives its name. It reaches a total length (including the tail) of up to . It is an adaptable predator inhabiting wooded areas, semidesert, urban edge, forest edge, and swampland environments. It remains in some of its original range, but populations are vulnerable to extirpation by coyotes and domestic animals. Though the bobcat prefers rabbits and hares, it hunts insects, chickens, geese and other birds, small rodents, and deer. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-tailed Kite
The white-tailed kite (''Elanus leucurus'') is a small raptor found in western North America and parts of South America. It replaces the related Old World black-winged kite in its native range. Taxonomy The white-tailed kite was described in 1818 by the French ornithologist Louis Jean Pierre Vieillot under the binomial name ''Milvus leucurus'' with the type locality as Paraguay. It is now one of four species in the genus '' Elanus'' which was introduced in 1809 by the French zoologist Jules-César Savigny. The word ''Elanus'' is from Ancient Greek ''elanos'' for a "kite". The specific epithet ''leucurus'' is from the Ancient Greek ''leukouros'' for "white-tailed": ''leukos'' is "white" and ''oura'' is "tail". For some recent decades, it was lumped with the black-winged kite of Europe and Africa as ''Elanus caeruleus'' and was collectively called black-shouldered kite. More recently it was argued that the white-tailed kite differed from the Old World species in size, shape, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
