Kediet Ej Jill
Kediet ej Jill () is a mountain in Tiris Zemmour, Mauritania, with the city of Zouérat on its east and Fderick at west. Geography At tall, Kediet ej Jill includes the highest peak in Mauritania. The mountain and its surrounding area are rich in iron deposits, thought to have been mined here since the 11th century and commercially exploited since 1952. The mines are connected to Nouadhibou on the Atlantic coast by a 700 km railway. Geology The mountain appears bluish because of the high concentration of magnetite, an iron ore and naturally magnetic.''European Space Agency''esa.int(access: August 2 2020) Owing to its inherent magnetic properties, the mountain disrupts navigational compasses. Similar magnetic fields allowed the discovery of other deposits in the region (magnetite guelbs) in the 1960s. Environment Ephemeral watercourses drain from the mountain escarpment into the surrounding desert. The vegetation includes ''Phoenix dactylifera'', ''Adiantum capillus-veneri ...

''Leptadenia pyrotechnica'' (; ) is the botanical name of a desert herb of the family Apocynaceae. It is widespread from Senegal to India. It is known as in Hindi and Urdu, and in Punjabi.L. R. Burdak (1982): Recent advances in desert afforestation, Dehradun, p.66 Being highly drought-resistant, ''Leptadenia pyrotechnica'' has played an important role in the desert afforestation programs. The herb is a strong soil binder and, as such, is one of the pioneer species in sand dune fixation. Description ''Leptadenia pyrotechnica'' is heavily branched and reaches heights of up to 3 metres. The shrub's long roots reach up to 12 metres below the surface. The leaves of the green to grey-green branches tend to fall off early. When present, they are opposite, sessile, elongated to linear, glabrous and about 2 cm long and 3 mm wide. The very small, greenish-yellow, hermaphrodite and five-fold, short-stalked flowers with a double inflorescence have a diameter of 2 mm and ...

Desert Lark
The desert lark (''Ammomanes deserti'') breeds in deserts and semi-deserts from Morocco to western India. It has a very wide distribution and faces no obvious threats, and surveys have shown that it is slowly increasing in numbers as it expands its range. The International Union for Conservation of Nature has rated its conservation status as being of "least concern". Taxonomy and systematics Originally, the desert lark was classified as belonging to the genus '' Alauda'' until moved to ''Ammomanes''. Alternate names include desert finch lark and sand lark. Subspecies Twenty-two subspecies are recognized: * Southern Moroccan desert lark (''A. d. payni'') - Hartert, 1924: Found in southern Morocco and south-western Algeria * Algerian desert lark or North Algerian desert lark (''A. d. algeriensis'') - Sharpe, 1890: Originally described as a separate species. Found in northern Algeria, Tunisia, north-western Libya and north-western Chad * South Algerian desert lark (''A. d. wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bar-tailed Lark
The bar-tailed lark or bar-tailed desert lark (''Ammomanes cinctura'') is a species of lark in the family Alaudidae. Two other species, the rufous-tailed lark and the Cape clapper lark are both also sometimes referred to using the name bar-tailed lark. It is found from Morocco to Pakistan. Its natural habitat is hot deserts. This is in many places a common species, but elsewhere rather less common. It has a very wide distribution and faces no obvious threats, but surveys have shown that it is slowly decreasing in numbers. The International Union for Conservation of Nature has rated its conservation status as being of "least concern". Taxonomy and systematics The bar-tailed lark was originally placed in the genus '' Melanocorypha''. Alternate names for the bar-tailed lark include: bar-tailed finch-lark, black-tailed desert lark, black-tailed lark, and black-tailed sand lark. Subspecies Three subspecies are recognized: * ''A. c. cinctura'' - ( Gould, 1839): Found on Cape Ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Hoopoe-lark
The greater hoopoe-lark (''Alaemon alaudipes'') is a Passeriformes, passerine bird which is a breeding resident of arid, desert and semi-desert regions from the Cape Verde Islands across much of northern Africa, through the Arabian Peninsula, Syria, Afghanistan, Pakistan and India. It was formerly known as the bifasciated lark and sometimes as the large desert lark. Taxonomy and systematics Formerly, the greater hoopoe-lark was classified as belonging to the genera ''Upupa'' and ''Certhilauda'' until moved to ''Alaemon''. The name Alaemon comes from the Greek alēmōn, meaning "wanderer" (from alaomai, meaning "to wander"). The genus was established by Alexander Keyserling and Johann Heinrich Blasius in 1840. Subspecies Four subspecies are recognized: * Cape Verde greater hoopoe-lark (''A. a. boavistae'') - Ernst Hartert, Hartert, 1917: Found on the Cape Verde Islands * North African greater hoopoe-lark (''A. a. alaudipes'') - (Rene Louiche Desfontaines, Desfontaines, 1789): Foun ...

Pharaoh Eagle-owl
The Pharaoh eagle-owl (''Bubo ascalaphus'') is a Middle Eastern and North African species of owl in the family Strigidae. Description The Pharaoh eagle-owl has a mottled plumage and large orange-yellow eyes. The head and upperparts are tawny and densely marked with black and creamy-white streaks and blotches, while the underparts are pale creamy-white, with black streaks on the upper breast and fine reddish-brown vermiculations on the lower breast and belly.

With a body length of , it is one of the smaller eagle-owl species. Two subspecies have been named, ''B. a. ascalaphus'' and ''B. a. desertorum'', the latter formerly cited as being smaller and paler with sandier colour; they are no longer accepted as distinct, as the variation is continuous and without geographic basis, so the species now regarded as monotypic.

Nubian Bustard
The Nubian bustard (''Neotis nuba'') is a species of bird in the bustard family.

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
