Southern Eastern Rift
The Southern Eastern Rift is a freshwater ecoregion in Kenya and Tanzania. It occupies the southern end of the Gregory Rift, 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) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. 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). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic frame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Singida
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large ...

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 the three peaks of Kilimanjaro are counted 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 forests cover the mountain's wetter eastern and southern slopes, while the drier western and northern slopes are home to dry montane evergreen forests with bushland and grassland on the ridges.

Mbulu Highlands
The Mbulu Highlands is a plateau in north-central Tanzania. Geography The Mbulu Highlands lie between the basins of Lake Eyasi to the west and Lake Manyara to the east. The plateau ranges from 1500 to 2300 meters in elevation. 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. Tanzania's B141 highway crosses the highlands, running through Mbulu on its way from Madukani east of the highlands to Singida in the southwest. Clima ...

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 ...

Mount Kilimanjaro
Mount Kilimanjaro () is a dormant volcano in Tanzania. It is the highest mountain in Africa and the highest free-standing mountain above sea level in the world, at above sea level and above its plateau base. It is also the highest volcano in the Eastern Hemisphere and the fourth most topographically prominent peak on Earth. Kilimanjaro's southern and eastern slopes served as the home of the Chagga Kingdoms until their abolition in 1963 by Julius Nyerere. The origin and meaning of the name Kilimanjaro is unknown, but may mean "mountain of greatness" or "unclimbable". Although described in classical sources, German missionary Johannes Rebmann is credited as the first European to report the mountain's existence, in 1848. After several European attempts, Hans Meyer reached Kilimanjaro's highest summit in 1889. The mountain was incorporated into Kilimanjaro National Park in 1973. As one of the Seven Summits, Kilimanjaro is a major hiking and climbing destination. There a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Meru, Tanzania
__NOTOC__ Mount Meru is a dormant stratovolcano located west of 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, and the highest mountain in Arusha Region. The Momella route – which starts at Momella gate, on the eastern side of the mountain – is the most common route for climbers to reach the peak. Mount Meru's lavas are alkaline in character and include nephelinite. Much of the mountain's height 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.

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 .
