Death Valley National Park is an American national park that straddles the California–Nevada border, east of the Sierra Nevada. The park boundaries include Death Valley, the northern section of Panamint Valley, the southern section of Eureka Valley, and most of Saline Valley. The park occupies an interface zone between the arid Great Basin and Mojave deserts, protecting the northwest corner of the Mojave Desert and its diverse environment of salt-flats, sand dunes, badlands, valleys, canyons, and mountains. Death Valley is the largest national park in the contiguous United States, and the hottest, driest and lowest of all the national parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, which is 282 feet (86 m) below sea level. Approximately 91% of the park is a designated wilderness area. The park is home to many species of plants and animals that have adapted to this harsh desert environment. Some examples include creosote bush, bighorn sheep, coyote, and the Death Valley pupfish, a survivor from much wetter times. UNESCO included Death Valley as the principal feature of its Mojave and Colorado Deserts Biosphere Reserve in 1984.
Mauritania, a country in the western region of the continent of Africa, is generally flat, its 1,030,700 square kilometres forming vast, arid plains broken by occasional ridges and clifflike outcroppings. It borders the North Atlantic Ocean, between Senegal and Western Sahara, Mali and Algeria. It is considered part of both the Sahel and the Maghreb. A series of scarps face southwest, longitudinally bisecting these plains in the center of the country. The scarps also separate a series of sandstone plateaus, the highest of which is the Adrar Plateau, reaching an elevation of 500 metres. Spring-fed oases lie at the foot of some of the scarps. Isolated peaks, often rich in minerals, rise above the plateaus; the smaller peaks are called guelbs and the larger ones kedias. The concentric Guelb er Richat is a prominent feature of the north-central region. Kediet ej Jill, near the city of Zouîrât, has an elevation of 1,000 metres and is the highest peak.

The Afrotropical realm is one of the Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region.
The Olympic Mountains are a mountain range on the Olympic Peninsula of the Pacific Northwest. The mountains, part of the Pacific Coast Ranges, are not especially high – Mount Olympus is the highest at 7,965 ft (2,428 m); however, the eastern slopes rise out of Puget Sound from sea level and the western slopes are separated from the Pacific Ocean by the low-lying 20 to 35 km wide Pacific Ocean coastal plain. The western slopes are the wettest place in the 48 contiguous states. Most of the mountains are protected within the bounds of Olympic National Park and adjoining segments of the Olympic National Forest.
Manaslu is the eighth-highest mountain in the world at 8,163 metres (26,781 ft) above sea level. It is in the Mansiri Himal, part of the Nepalese Himalayas, in the west-central part of Nepal. Its name, which means "mountain of the spirit", comes from the Sanskrit word manasa, meaning "intellect" or "soul". Manaslu was first climbed on May 9, 1956 by Toshio Imanishi and Gyalzen Norbu, members of a Japanese expedition. It is said that "just as the British consider Everest their mountain, Manaslu has always been a Japanese mountain".
Rapti Zone was one of the fourteen zones, located in the Mid-Western Development Region of Nepal. It was named after the West Rapti River which drains Rolpa, Pyuthan and part of Dang districts. The remainder of Dang and part of Salyan district are drained by the Babai. The remainder of Salyan and all of Rukum districts are drained by the Bheri.
Charles Pickering was an American race scientist and naturalist.
Valley of Flowers National Park is an Indian national park, located in North Chamoli, in the state of Uttarakhand and is known for its meadows of endemic alpine flowers and the variety of flora. This richly diverse area is also home to rare and endangered animals, including the Asiatic black bear, snow leopard, musk deer, brown bear, red fox and blue sheep. Birds found in the park include Himalayan monal pheasant and other high altitude birds. At 3352 to 3658 meters above sea level, the gentle landscape of the Valley of Flowers National Park complements the rugged mountain wilderness of Nanda Devi National Park to the east. Together, they encompass a unique transition zone between the mountain ranges of the Zanskar and Great Himalaya. The park stretches over an expanse of 87.50 km2 and it is about 8 km long and 2 km wide. Both parks are encompassed in the Nanda Devi Biosphere Reserve which is further surrounded by a buffer zone (5,148.57 km2). Nanda Devi National Park Reserve is in the UNESCO World Network of Biosphere Reserves.
The Pacific Ranges are the southernmost subdivision of the Coast Mountains portion of the Pacific Cordillera. Located entirely within British Columbia, Canada, they run northwest from the lower stretches of the Fraser River to Bella Coola and Burke Channel, north of which are the Kitimat Ranges. The Coast Mountains lie between the Interior Plateau and the Coast of British Columbia.
Phytogeography or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. Phytogeography is concerned with all aspects of plant distribution, from the controls on the distribution of individual species ranges to the factors that govern the composition of entire communities and floras. Geobotany, by contrast, focuses on the geographic space's influence on plants.
Ascreavie is a country house in Angus, Scotland. It is located 2 kilometres (1.2 mi) north of Kirkton of Kingoldrum, and 6 kilometres (3.7 mi) north-west of Kirriemuir. The farms of Over Ascreavie and Nether Ascreavie lie close by. In 1987 the gardens at Ascreavie were added on the Inventory of Gardens and Designed Landscapes in Scotland for its important horticultural collection, gathered by the plant-hunter George Sherriff. They were removed from the inventory in 2017.
The Walker Lane is a geologic trough roughly aligned with the California/Nevada border southward to where Death Valley intersects the Garlock Fault, a major left lateral, or sinistral, strike-slip fault. The north-northwest end of the Walker Lane is between Pyramid Lake in Nevada and California's Lassen Peak where the Honey Lake Fault Zone, the Warm Springs Valley Fault, and the Pyramid Lake Fault Zone meet the transverse tectonic zone forming the southern boundary of the Modoc Plateau and Columbia Plateau provinces. The Walker Lane takes up 15 to 25 percent of the boundary motion between the Pacific Plate and the North American Plate, the other 75 percent being taken up by the San Andreas Fault system to the west. The Walker Lane may represent an incipient major transform fault zone which could replace the San Andreas as the plate boundary in the future.

Arctomecon merriamii is a species of poppy known by several common names, including desert bearpoppy, white bearpoppy, and great bearclaw poppy. It is native to the Mojave Desert of California and Nevada.
The Brigalow Belt is a wide band of acacia wooded grassland that runs between tropical rainforest of the coast and the semi-arid interior of Queensland, Australia. See Interim Biogeographic Regionalisation for Australia for the IBRA definitions of the Brigalow Belt South (BBS) and the Brigalow Belt North (BBN) bioregions. The Northern and Southern Brigalow Belts are two of the 85 bioregions across Australia and the 15 bioregions in Queensland. Together they form most of the Brigalow tropical savanna ecoregion.
A zonal plant is a “species or variety which is of value in determining floral zones.” Botanist Frederick Vernon Coville defined the expression. He described "the best method of procedure in a new area to establish the (floral) zones by means of a comparatively small number of the best zonal plants, and afterwards to arrange the other less important [plants] in their proper places."
The Death Valley expedition was an 1891 expedition to discover the geographic distributions of plants (phytogeography) and animals in California's Death Valley.
The geology of Mongolia is made up a complicated array of microcontinents and island chains accreted together over the past half billion years, producing varied terrain and tectonics.
