Niokolo-Koba
The Niokolo-Koba National Park (french: Parc National du Niokolo Koba, PNNK) is a World Heritage Site and natural protected area in south eastern Senegal near the Guinea border. It is served by Niokolo-Koba Airport, an unpaved airstrip. National Park Established as a reserve in 1925, Niokolo-Koba was declared a Senegalese national park on 1 January 1954. Expanded in 1969, it was inscribed as a World Heritage Site in 1981 as a UNESCO-MAB Biosphere Reserve. In 2007 it was added to the UNESCO List of Endangered World Heritage sites. Since 2005, the protected area is considered a Lion Conservation Unit. Geography The park lies in an upland region through which the upper stretch of the Gambia River flows, towards the northwestern border of Guinea. The Biosphere park itself covers some 9,130 square kilometres, in a great arc running from Upper Casamance/Kolda Region at the Guinea-Bissau border into the Tambacounda Region to within a hundred kilometers of the Guinean border ne ...

Giant Eland
The giant eland (''Taurotragus derbianus''), also known as the Lord Derby eland and greater eland, is an open-forest and savanna antelope. A species of the family Bovidae and genus ''Taurotragus'', it was described in 1847 by John Edward Gray. The giant eland is the largest species of antelope, with a body length ranging from . There are two subspecies: ''T. d. derbianus'' and ''T. d. gigas''. The giant eland is a herbivore, eating grasses, foliage and branches. They usually form small herds consisting of 15–25 members, both males and females. Giant elands are not territorial, and have large home ranges. They are naturally alert and wary, which makes them difficult to approach and observe. They can run at up to and use this speed as a defence against predators. Mating occurs throughout the year but peaks in the wet season. They mostly inhabit broad-leafed savannas, woodlands and glades. The giant eland is native to Cameroon, Central African Republic, C ...

List Of World Heritage Sites In Africa
The United Nations Educational, Scientific and Cultural Organization (UNESCO) has designated 147 World Heritage Sites in Africa. These sites are located in 46 countries (also called " state parties"). Selection of World Heritage Sites South Africa has the lead with ten sites; followed by Ethiopia and Morocco being home to nine sites; then Tunisia with eight sites; and Algeria, Egypt, Senegal, and Tanzania at seven. Nine countries have only a single site each. Four sites are shared between two countries: Maloti-Drakensberg Park (Lesotho and South Africa), the Mount Nimba Strict Nature Reserve (Côte d'Ivoire and Guinea), the Stone Circles of Senegambia (the Gambia and Senegal), and Mosi-oa-Tunya / Victoria Falls (Zambia and Zimbabwe). Two sites are shared among three countries: Sangha Trinational (Central African Republic, Cameroon, and Congo) and W-Arly-Penjari Complex (Benin, Burkina Faso, and Niger).. The first sites from the continent were inscribed in 1978, when the Isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of World Heritage In Danger
The List of World Heritage in Danger is compiled by the United Nations Educational, Scientific and Cultural Organization (UNESCO) through the World Heritage Committee according to Article 11.4 of the World Heritage Convention,Full title: ''Convention concerning the protection of the World Cultural and Natural Heritage'' which was established in 1972 to designate and manage World Heritage Sites. Entries in the list are threatened World Heritage Sites for the conservation of which major operations are required and for which "assistance has been requested". The list is intended to increase international awareness of the threats and to encourage counteractive measures. Threats to a site can be either proven imminent threats or potential dangers that could have adverse effects on a site. In the case of natural sites, ascertained dangers include the serious decline in the population of an endangered or other valuable species or the deterioration of natural beauty or scientific value o ...

West African Lion
''Panthera leo leo'' is a lion subspecies, which is present in West Africa, northern Central Africa and India. In West and Central Africa it is restricted to fragmented and isolated populations with a declining trajectory. It has been referred to as the Northern lion. Results of a phylogeographic study indicate that lion populations in West and Central African range countries are genetically close to populations in India, forming a major clade distinct from lion populations in Southern and East Africa. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations according to the major clades into two subspecies, namely ''P. l. leo'' and ''P. l. melanochaita''. Within ''P. l. leo'' three subclades are clearly distinguishable. One from Asia, which includes the extinct Barbary lions of North Africa, another one from West Africa and a third one from Central Africa, north of the rainforest belt. ''P. l. leo'' is regionally extinct in Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tambacounda Region
Tambacounda, formerly known as ''Sénégal Oriental'', is a region of Senegal. It used to be part of the Mali Empire before the borders were created to separate Mali from Senegal. Tambacounda is physically the largest of Senegal's 14 regions, but is sparsely populated and its economy lags behind the rest of the country. The department of Kédougou was separated from Tambacounda in 2008, and became a separate region. Departments Tambacounda region is divided into 4 departments: * Bakel Département * Goudiry Département * Koumpentoum Département * Tambacounda Département Geography Tambacounda is traversed by the northwesterly line of equal latitude and longitude. Culture Tambacounda is famous for its rich djembe and dance culture and heritage. Some of the greatest djembe masters from Segu, Mali came to Tambacounda in the mid 1900s, bringing with them their history, knowledge, and secrets of the djembe. Its official language is French, but Wolof is more widely spoken in Sén ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gambia River
The Gambia River (formerly known as the River Gambra) is a major river in West Africa, running from the Fouta Djallon plateau in north Guinea westward through Senegal and The Gambia to the Atlantic Ocean at the city of Banjul. It is navigable for about half that length. The river is strongly associated with The Gambia, the smallest country in mainland Africa, which occupies the downstream half of the river and its two banks. Geography The Gambia River runs a total length of . From the Fouta Djallon, it runs northwest into the Tambacounda Region of Senegal, where it flows through the Parc National du Niokolo Koba, then is joined by the Nieri Ko and and passing through the Barrakunda Falls before entering the Gambia at Koina. At this point, the river runs generally west, but in a meandering course with a number of oxbows, and about from its mouth it gradually widens, to over wide where it meets the sea. Crossings There are several bridges crossing the river. The largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Park
A national park is a natural park in use for conservation purposes, created and protected by national governments. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. The United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. However, the Tobago Main Ridge Forest Reserve (in what is now Trinidad and Tobago; established in 1776), and the area surrounding Bogd Khan Uul Mountain (Mongolia, 1778), which were restricted from cultivation in order to pr ...

Soil Compaction
In geotechnical engineering, soil compaction is the process in which stress applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation, not compaction, has occurred. Normally, compaction is the result of heavy machinery compressing the soil, but it can also occur due to the passage of, for example, animal feet. In soil science and agronomy, soil compaction is usually a combination of both engineering compaction and consolidation, so may occur due to a lack of water in the soil, the applied stress being internal suction due to water evaporation as well as due to passage of animal feet. Affected soils become less able to absorb rainfall, thus increasing runoff and erosion. Plants have difficulty in compacted soil because the mineral grains are pressed together, leaving little space for air and water ...

Mimosa Pigra
''Mimosa pigra'', commonly known as the giant sensitive tree (''pigra'' = lazy, slow), is a species of plant of the genus ''Mimosa'', in the family Fabaceae. The genus ''Mimosa'' (Mimosaceae) contains 400–450 species, most of which are native to South America. ''M. pigra'' is a woody shrub native to tropical America but which has now become widespread throughout the tropics. In Groves R.H., Sheppard R.C.H., Richardson R.G. ''The biology of Australian weeds'' R.G. and F.J. Richardson Publishers, Melbourne, Australia. It has been listed as one of the world's 100 worst invasive species and forms dense, thorny, impenetrable thickets, particularly in wet areas. Taxonomy ''Mimosa pigra'' was first identified by Linnaeus, who also named a separate species ''Mimosa asperata'', on the basis of its different leaf morphology. ''Mimosa pigra'' was described as having an erect prickle between the pinnae and ''Mimosa asperata'' as having prickles in opposite pairs between the pinnae. Furt ...

Warthog Niokolo Koba
''Phacochoerus'' is a genus in the family Suidae, commonly known as warthogs (pronounced ''wart-hog''). They are pigs who live in open and semi-open habitats, even in quite arid regions, in sub-Saharan Africa. The two species were formerly considered conspecific under the scientific name ''Phacochoerus aethiopicus'', but today this is limited to the desert warthog, while the best-known and most widespread species, the common warthog (or simply warthog), is ''Phacochoerus africanus''. Skull Although covered in bristly hairs, their bodies and heads appear largely naked from a distance, with only the crest along the back, and the tufts on their cheeks and tails being obviously haired. The English name refers to their facial wattles, which are particularly distinct in males. They also have very distinct tusks, which reach a length of in the males, but are always smaller in the females.Novak, R. M. (editor) (1999). ''Walker's Mammals of the World.'' Vol. 2. 6th edition.

Amphibian
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramat ...
