Providence Mountains State Recreation Area
The Providence Mountains State Recreation Area is located in the Providence Mountains, within the Mojave National Preserve in San Bernardino County, California. It is also home to the Mitchell Caverns Natural Preserve. Geography The Recreation Area is located on the east side of the Providence Mountain range and has dramatic views of the surrounding Mojave Desert. On approaching the Providence Mountains State Recreation Area one can see layers of tilted grey rock that are ancient limestone formed during the Paleozoic Era. The base elevation of the park is 4,300 feet with the Providence Mountains reaching to 7000 feet. Flora Vegetation on the lower parts of the mountains is xeric shrublands scrub habitat, composed of creosote bush (''Larrea tridentata''), California barrel cactus (''Ferocactus cylindraceus''), and Mojave yucca (''Yucca schidigera''). The habitat dramatically shifts with elevations above 4000 feet to a sky island where numerous animals and plants flourish in t ...

Sky Island
Sky islands are topographic isolation, isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau, and has extended to similarly isolated montane ecosystems, high-elevation forests. The isolation has significant implications for these natural habitats. The Southwestern United States, American Southwest region began warming up between and 10,000 years Before Present, BP and atmospheric temperatures increased substantially, resulting in the formation of vast deserts that isolated the sky islands. Endemism, altitudinal migration, and Relict (biology), relict populations are some of the natural phenomena to be found on sky islands. The complex dynamics of species richness on sky islands draws attention from the discipline of biogeography, and likewise the biodiversity is of concern to conservation biology. One of the key elements of a sky island is separation by physical distance from the other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protected Areas Of The Mojave Desert
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 (botany), 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 Scale (anatomy), scales and hair offer further protection from the elements and from predators, with some animals having features such ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manzanita
Manzanita is a common name for many species of the genus ''Arctostaphylos''. They are evergreen shrubs or small trees present in the chaparral biome of western North America, where they occur from Southern British Columbia and Washington to Oregon, California, Utah, Arizona, New Mexico, and Texas in the United States, and throughout Mexico. Manzanitas can live in places with poor soil and little water. They are characterized by smooth orange or red bark and stiff, twisting branches. There are 105 species and subspecies of manzanita, 95 of which are found in the Mediterranean climate and colder mountainous regions of California, ranging from ground-hugging coastal and mountain species to small trees up to 20 feet (6m) tall. Manzanitas bloom in the winter to early spring and carry berries in spring and summer. The berries and flowers of most species are edible. The word ''manzanita'' is the Spanish diminutive of ''manzana'' (apple). A literal translation would be ''little apple' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Description ''Juniperus californica'' is a shrub or small tree reaching , but rarely up to tall. The bark is ashy gray, typically thin, and appears to be "shredded". The shoots are fairly thick compared to most junipers, between in diameter. The foliage is bluish-gray and scale-like. The juvenile leaves (on the seedlings) are needle-like and long. Arranged in opposite decussate pairs or whorls of three, the adult leaves are scale-like, long on lead shoots and broad.
