Bitter Creek National Wildlife Refuge
The Bitter Creek National Wildlife Refuge is located in the foothills of the southwestern San Joaquin Valley in Kern County, California. The refuge is one of four units of the Hopper Mountain National Wildlife Refuge Complex for California condors. California condors Elevations on the Refuge range from . Purchased to protect dwindling California condor foraging and roosting habitat in 1985, the refuge is the site where the last wild female condor was trapped in 1986. The reintroduced condors feed and roost on the refuge. The refuge is an integral part of the Service's condor monitoring activities. The most notable physical features of the refuge are the San Andreas Fault, which bisects the refuge, and the dramatic Bitter Creek Canyon. As of July 2014, there is a total population of 437 condors living in sites in California, Baja California and Arizona. This includes a wild population of 232 and a captive population of 205. Sixty-eight free-flying Condors are managed by the US Fi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spea Hammondii
''Spea hammondii'', also known as the western spadefoot, western spadefoot toad, Hammond's spadefoot, or Hammond's spadefoot toad, is a species of amphibian in the family Scaphiopodidae. It is found in western California (USA) and northwestern Baja California (Mexico). The specific name ''hammondii'' is in honor of physician and naturalist William Alexander Hammond. Description Spea hammondii is a relatively smooth-skinned species of American spadefoot toad. Its eyes are pale gold with vertical pupils. It has a green or grey dorsum, often with skin tubercles tipped in orange, and has a whitish color on the abdomen. On each hind foot is a wedge-shaped black spade. Adult toads are between long.

Wetlands Of California
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland typ ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Protected Areas Of Kern County, California
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Protected Areas Of The Sierra Nevada (United States)
The protected areas of the Sierra Nevada, a major mountain range located in the U.S. states of California and Nevada, are numerous and highly diverse. Like the mountain range itself, these areas span hundreds of miles along the length of the range, and over 14,000 feet of elevation from the lowest foothills to the summit of Mount Whitney. The Sierra Nevada, as a natural region, does not have exactly defined borders. In particular, to the north, there is a wide transition zone where the Cascade Range and the Sierra Nevada meet. As a result, it is difficult to delineate a border between these two mountain ranges. This list uses the common definition of the Sierra Nevada as the mountain range extending from Fredonyer Pass in the north to Tehachapi Pass in the south. It is also difficult to delineate between the Sierra Nevada mountains, the range's foothills, and the Central Valley; this article also considers any elevated and hilly terrain east of the flat Central Valley to be par ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ...

Tule Elk
The tule elk (''Cervus canadensis nannodes'') is a subspecies of elk found only in California, ranging from the grasslands and marshlands of the Central Valley to the grassy hills on the coast. The subspecies name derives from the tule (), a species of sedge native to freshwater marshes on which the Tule elk feeds. When the Europeans first arrived, an estimated 500,000 tule elk roamed these regions, but by 1870 they were thought to be extirpated. However, in 1874–1875 a single breeding pair was discovered in the tule marshes of Buena Vista Lake in the southern San Joaquin Valley. Conservation measures were taken to protect the species in the 1970s. Today, the wild population exceeds 4,000. Tule elk can reliably be found in Carrizo Plain National Monument, Point Reyes National Seashore, portions of the Owens Valley from Lone Pine to Bishop, on Coyote Ridge in Santa Clara Valley, San Jose, California and in Pacheco State Park and areas surrounding San Luis Reservoir near Los ...

Pronghorn
The pronghorn (, ) (''Antilocapra americana'') is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae. During the Pleistocene epoch, about 11 other antilocaprid species existed in North America.Smithsonian Institution. North American MammalsPronghorn ''Antilocapra americana''/ref> Three other genera (''Capromeryx'', '' Stockoceros'' and ''Tetrameryx'') existed when humans entered North America but are now extinct. As a member of the superfamily Giraffoidea, the pronghorn's closest living relatives are the giraffe and okapi. See Fig. S10 in Supplementary Information. The Giraffoidea are in tu ...

Mule Deer
The mule deer (''Odocoileus hemionus'') is a deer indigenous to western North America; it is named for its ears, which are large like those of the mule. Two subspecies of mule deer are grouped into the black-tailed deer. Unlike the related white-tailed deer (''Odocoileus virginianus''), which is found throughout most of North America east of the Rocky Mountains and in the valleys of the Rocky Mountains from Idaho and Wyoming northward, mule deer are only found on the western Great Plains, in the Rocky Mountains, in the southwest United States, and on the west coast of North America. Mule deer have also been introduced to Argentina and Kauai, Kauai, Hawaii. Taxonomy Mule deer can be divided into two main groups: the mule deer (''sensu stricto'') and the black-tailed deer. The first group includes all subspecies, except ''O. h. columbianus'' and ''Sitka deer, O. h. sitkensis'', which are in the black-tailed deer group. The two main groups have been treated as separate species, but ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mountain Lion
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 ...
