Southern Eastern Rift
The Southern Eastern Rift is a freshwater ecoregion in Kenya and Tanzania. It occupies the southern end of the Eastern Rift Valley, or Gregory Rift, and includes a number of closed or endorheic basins which drain into central lakes with no outlet to the sea. The Southern Eastern Rift extends 700 km, from central Kenya to Central Tanzania. The Eastern Rift Valley is 50 to 100 km wide for most of its length, but widens out at its southern end. The lake basins are, from north to south, Lake Baringo, Lake Bogoria, Lake Nakuru, Lake Naivasha, Lake Elementaita, and Lake Magadi in Kenya, and Lake Natron, Lake Manyara, Lake Burungi, Lake Eyasi, Lake Kitangiri, Lake Balangida, Lake Singida, and Lake Sulunga in Tanzania."Southern Eastern Rift" "Freshwater Ecoregions of the World".

Freshwater Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Singida
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hanang
Mount Hanang is a mountain in northern Tanzania. The peak has an elevation of 3,420 m above sea level. Hanang is located in Manyara Region's Hanang District. It is (after Mount Kilimanjaro, Mount Meru and Mount Loolmalasin) the fourth-highest mountain in Tanzania, if you count the three peaks of Kilimanjaro as one mountain. The principal path to the summit starts in the town of Katesh. The climb can be done in one day (10 hours), but it is also common for climbers to spend one night in a tented camp on the mountain and reach the summit on the second day. Hanang Forest Reserve Mount Hanang Nature Forest Reserve has an area of 58.66 km², protecting an enclave of evergreen montane forest on the mountain's higher slopes. Between 2000 and 2700 meters elevation, evergreen montane forest covers the mountain's wetter eastern and southern slopes, while the drier western and northern slopes are home to dry montane evergreen forest with bushland and grassland on the ridges. Above 2700 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mbulu Highlands
The Mbulu Highlands is a plateau in north-central Tanzania. The Mbulu Highlands lie between the basins of Lake Eyasi to the west and Lake Manyara to the east. The highlands extend northeast-southwest. A steep northeast-southwest-running escarpment bounds the highlands on the east, overlooking the basins of Lake Manyara, and further south, Lake Balangida. The plateau descends less steeply in a series of ridges and valleys to Lake Eyasi to the west and the Yaeda Valley to the southwest. To the north lies the volcanic Ngorongoro Highlands. The volcanic peak of Mount Hanang rises south of Lake Balangida. The highlands lie mostly in Mbulu District of Manyara Region, extending northwards into Karatu District of Arusha Region. The principal town on the plateau is Mbulu. The plateau ranges from 1500 to 2300 meters in elevation. Mean annual rainfall is 1000 mm or more in the highlands, higher than in the surrounding lowlands. Rainfall can vary greatly from year to year. June to Septemb ...

Wembere River
The Wembere River is a river located in north western Singida Region, Tanzania. The river is part of the water basin of Lake Eyasi. The Wembere River originates in hilly country in central Tanzania at 6.0º south, and flows northwards through a branch of the Eastern Rift Valley. Its tributary the Nyahua River forms a seasonal floodplain 60 miles long and 1-5 km wide, covering 11,000 ha. After the Nyahua joins the Wembere from the northwest, the Wembere widens into a larger floodplain 105 km long and up to 20 km wide, and covering 140,000 ha. (4º12'-5º01' S/33º47'-34º11' E). Other tributaries are the Wamba, which joins from the northeast, the Mwaru, which joins from the east, and the Mapiringa, which joins from the west. The floodplain consists of flooded grasslands, inundated during the wet season and laced with drainage channels. Stands of the trees ''Vachellia seyal'' and ''Vachellia drepanolobium'' edge the seasonally-flooded portion of the plain. Above the floodplain, th ...

Mount Kilimanjaro
Mount Kilimanjaro () is a dormant volcano in Tanzania. It has three volcanic cones: Kibo, Mawenzi, and Shira. It is the highest mountain in Africa and the highest free-standing mountain above sea level in the world: above sea level and about above its plateau base. It is the highest volcano in Africa and the Eastern Hemisphere. Kilimanjaro is the fourth most topographically prominent peak on Earth. It is part of Kilimanjaro National Park and is a major hiking and climbing destination. Because of its shrinking glaciers and ice fields, which are projected to disappear between 2025 and 2035, it has been the subject of many scientific studies. Toponymy The origin of the name Kilimanjaro is not known, but a number of theories exist. European explorers had adopted the name by 1860 and reported that Kilimanjaro was the mountain's Kiswahili name. The 1907 edition of ''The Nuttall Encyclopædia'' also records the name of the mountain as Kilima-Njaro. Johann Ludwig Krapf ...

Mount Meru, Tanzania
__NOTOC__ Mount Meru is a dormant stratovolcano located west of Mount Kilimanjaro in southeast Arusha Region, Tanzania. At a height of , it is visible from Mount Kilimanjaro on a clear day, and is the fifth-highest of the highest mountain peaks of Africa, dependent on definition. Mount Meru is located just north of the city of Arusha, in the Arusha Region of Tanzania. It is the second-highest mountain in Tanzania, after Mount Kilimanjaro. Mount Meru is also the highest mountain/point in Arusha Region. The Momella route – which starts at Momella gate, on the eastern side of the mountain – is used to climb Mount Meru. Much of its bulk was lost about 7,800 years ago due to a summit collapse. Mount Meru most recently had a minor eruption in 1910. The several small cones and craters seen in the vicinity probably reflect numerous episodes of volcanic activity. Mount Meru's caldera is wide. Mount Meru is the topographic centerpiece of Arusha National Park. Its fertile slopes ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ngorongoro Highlands
The Crater Highlands (Ngorongoro Highlands) are a geological region along the East African Rift in the Arusha Region Arusha City is a Tanzanian city and the regional capital of the Arusha Region, with a population of 416,442 plus 323,198 in the surrounding Arusha District Council (2012 census). Located below Mount Meru on the eastern edge of the eastern ... and parts of northern Manyara Region in north Tanzania. Geology The highlands are located in a spreading zone at the intersection of branches of two tectonic plates, the African Plate and Somali Plate, resulting in distinctive and prominent landforms. The highlands are named for the many Volcanic crater, craters and calderas present. As is common in spreading zones, volcanoes can be found here. Magma, rising to fill the gaps, reaches the surface and builds cones. Calderas form if a volcano explodes or collapses, following the emptying of the magma chamber below, and further spreading can fracture the volcanoes as ...

Serengeti Volcanic Grasslands
The Serengeti volcanic grasslands is a tropical grassland ecoregion of Tanzania. The Serengeti volcanic grasslands are distinctive grasslands growing on deposits of volcanic ash in northern Tanzania. It includes the eastern portion of Serengeti National Park and areas south and east of the Ngorongoro Highlands. Topography The Serengeti volcanic grasslands are an edaphic plant community that grows on soils derived from volcanic ash. The eruption of the now-extinct Kerimasi volcano 150,000 years ago deposited huge amounts of fine whitish-grey ash. More recent eruptions of the Ol Doinyo Lengai volcano deepened the ash deposits. These ash deposits hardened with time, creating layers of calcareous tuff and calcitic hard-pan soil. The flat or slightly undulating plains are interrupted here and there by rocky kopjes, outcrops of the underlying Precambrian rocks. The terrain lies at a mean altitude of , rising to a maximum of .
