Afrocarpus Dawei
''Afrocarpus dawei'' is a species of conifer in the family Podocarpaceae. It is native to Africa, where it occurs in the Democratic Republic of the Congo, Tanzania, and Uganda. This species is a tree that grows in swampy forest habitat that is flooded in the rainy season. It is associated with '' Baikiaea insignis'' and ''Mimusops'' species. ''A. dawei'' is found in the Minziro Forest of Tanzania and the adjacent Sango Bay forests of Uganda, located west of Lake Victoria.

Otto Stapf (botanist)
Otto Stapf FRS (23 April 1857, in Perneck near Bad Ischl – 3 August 1933, in Innsbruck) was an Austrian born botanist and taxonomist, the son of Joseph Stapf, who worked in the Hallstatt salt-mines. He grew up in Hallstatt and later published about the archaeological plant remains from the Late Bronze- and Iron Age mines that had been uncovered by his father. Stapf studied botany in Vienna under Julius Wiesner, where he received his PhD with a dissertation on cristals and cristalloids in plants. 1882 he became assistant professor (''Assistent'') of Anton Kerner. In 1887 he was made ''Privatdozent'' (lecturer without a chair) in Vienna. He published the results of an expedition Jakob Eduard Polak, the personal physician of Nasr al-Din, the Shah of Persia, had conducted in 1882, and plants collected by Felix von Luschan in Lycia and Mesopotamia 1881–1883. In 1885, Polak sponsored Stapf to conduct a botanical expedition of his own to South- and Western Persia, which was to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sango Bay Forests
The Sango Bay forests are distinctive forests found in southwestern Uganda, near the border with Tanzania. The Sango Bay forests grow on seasonally-flooded lowlands near on the lower reaches of the Kagera River, just west of where it empties into Lake Victoria. Geography The Sango Bay forests lie in Rakai District. They extend north and west of the lower Kagera River, on alluvial soils deposited by the river – predominantly clay, with sandy soils in the northern portion. The town of Minziro lies in the center of the forested area, near the Tanzanian border. The towns of Kanabulemu and Sango Bay are on the forests' eastern edge. Climate The climate of the region is tropical. Average annual rainfall ranges from 1,250 and 2,125 mm, with two rainy seasons. The main rainy season is from March to May, with shorter rains falling during September through November. Average annual temperatures range from 16º to 26ºC. Seasonal floods occur during the March to May rainy season. Ecology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afromontane Flora
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands. Geography Afromontane communities occur above elevation near the equator, and as low as elevation in the Knysna-Amatole montane forests of South Africa. Afromontane forests are generally cooler and more humid than the surrounding lowlands. The Afromontane archipelago mostly follows the East African Rift from the Red Sea to Zimbabwe, with the largest areas in the Ethiopian Highlands, the Albertine Rift Mountains of Uganda, Rwanda, Burundi, Democratic Republic of the Congo, and Tanzania, and the Eastern Arc highlands of Kenya and Tanza ...

Trees Of Africa
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Uganda
Flora is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Near-threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Kagera River
The Kagera River, also known as Akagera River, or Alexandra Nile, is an East African river, forming part of the upper headwaters of the Nile and carrying water from its most distant source.Stanley, H.M., 1899, Through the Dark Continent, London: G. Newnes, With a total length of from its source located in Lake Rweru in Rwanda. The section of river named Kagera begins in Burundi, flowing out from Lake Rweru. From the lake, it flows east along the Rwanda-Burundi and Rwanda-Tanzania borders to a confluence with the Ruvubu River. The waters of the Kagera are thus provided by two major tributaries, the Nyabarongo of Rwanda, which feeds Lake Rweru, and the Ruvubu of Burundi. It is unknown which of these two feeder rivers is the longer and hence the ultimate source of the Nile. From the confluence, the Kagera flows north along the Rwanda-Tanzania border, over Rusumo Falls and through Akagera National Park. It then takes a turn to the east, following the Tanzania-Uganda border and em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minziro Forest
The Minziro (Nature) Forest Reserve is a conservation area along the Kagera River in Bukoba district of northwestern Tanzania. It protects one of the largest forests in Tanzania, of a forest type that is unique in the country. It was gazetted in 1947 and is situated at an elevation of around . in fairly level terrain. The forest is continuous with the Malabigambo Forest over the nearby Uganda border. The largest part consists of '' Baikiaea''–''Podocarpus'' seasonal swamp forests while the remainder is flooded acacia woodlands. Wildlife The Minziro Forest is similar to forests found in the Congo and Guinea, and consequently it contains flora and fauna that reach their eastern range limits here. Characteristic trees of swamp forests include ''Afrocarpus dawei, Heywoodia lucens, Mussaenda erythrophylla, Cassipourea ruwensorensis, Citropsis articulata, Manilkara obvata, Baikiaea insignis,'' and ''Uncaria africana''.Kamukala, G.
