Oreobambos
''Oreobambos buchwaldii'' is the sole representative of ''Oreobambos'', a monotypic African genus of bamboo, most closely related to the large genus ''Bambusa'' from tropical Asia and America. It is large and perennial with arching stems up to 20 m. high, growing in isolated clumps, in forest clearings and swamp forest, and along streams, at altitudes of 300–2000 m. It occurs along the tropical east of Africa in eastern DR Congo, Burundi, Kenya, Uganda, Tanzania, Mozambique, Malawi, Zimbabwe and Zambia. This is one of only a handful of indigenous African bamboos. Lateral branches are dendroid. Sheaths are covered in appressed, dark brown hairs when young. Leaves are 10-35 x 2·5–6 cm., lanceolate to oblong-lanceolate, and obscurely tessellate. Leaf-blade apex is acuminate, while the base is broadly rounded, with a small petiole-like connection to the sheath. Leaf-blades are deciduous at the ligule. Culm-internodes are hollow and 5–10 cm. in diameter. Flowering pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moribane Forest Reserve
The 144 km2 Moribane Forest Reserve (Portuguese: Reserva Florestal de Moribane) which was proclaimed in 1957, is a natural forest in the buffer zone of the 640 km2 Chimanimani National Reserve, and is situated 24 km north of Dombé, in Sussundenga District of central Mozambique. The mid to low-altitude tropical rain forest covers hilly country, from 400 to 550 metres in altitude, on the eastern verges of the largest southern African forest of this type, altogether 820 km2 in extent. It can be reached using public transport from Sussundenga. Flora and fauna Flora Müller et al. (2005) described two main vegetation types, namely a) moist, evergreen forest dominated by Forest newtonia ''(Newtonia buchananii)'', Chirinda stinkwood ''(Celtis mildbraedii)'', Forest ordeal tree ''(Erythrophleum suaveolens)'', and Panga-panga ''(Millettia stuhlmannii)'', and b) transitional forest on the northern verge of the forest, where the predominant species were Winged ber ...

Bambusoideae Genera
Bamboos are a diverse group of evergreen perennial flowering plants making up the subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow within a 24-hour period, at a rate of almost an hour (equivalent to 1 mm every 90 se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zambia
Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central Africa, Central, Southern Africa, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are the Democratic Republic of the Congo to the north, Tanzania to the northeast, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The nation's population of around 19.5 million is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country. Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following the arrival of European exploration of Africa, European explorers in the eighteenth century, the British colonised the r ...

Grasses Of Africa
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Genetic Erosion
Genetic erosion (also known as genetic depletion) is a process where the limited gene pool of an endangered species diminishes even more when reproductive individuals die off before reproducing with others in their endangered low population. The term is sometimes used in a narrow sense, such as when describing the loss of particular alleles or genes, as well as being used more broadly, as when referring to the loss of a phenotype or whole species. Genetic erosion occurs because each individual organism has many unique genes which get lost when it dies without getting a chance to breed. Low genetic diversity in a population of wild animals and plants leads to a further diminishing gene pool – inbreeding and a weakening immune system can then "fast-track" that species towards eventual extinction. By definition, endangered species suffer varying degrees of genetic erosion. Many species benefit from a human-assisted breeding program to keep their population viable, thereby avoi ...

Usambara Mountains
The Usambara Mountains of northeastern Tanzania in tropical East Africa, comprise the easternmost ranges of the Eastern Arc Mountains. The ranges of approximately long and about half that wide, are situated in the Lushoto District of the Tanga Region. They were formed nearly two million years ago by faulting and uplifting, and are composed of Precambrian metamorphic rocks. They are split into two sub-ranges; the West Usambaras being higher than the East Usambaras, which are nearer the coast and receive more rainfall. The mountains are clad in virgin tropical rainforest which has been isolated for a long period and they are a centre of endemism. Historically they were inhabited by Bantu, Shambaa, and Maasai people but in the eighteenth century, a Shambaa kingdom was founded by Mbegha. The kingdom eventually fell apart after a succession struggle in 1862. German colonists settled in the area which was to become German East Africa, and after World War I it became part of the ...

Shire Highlands
The Shire Highlands are a plateau in southern Malawi, located east of the Shire River. It is a major agricultural area and the most densely populated part of the country. Geography The highlands cover an area of roughly 7250 square kilometers. the plateau varies in elevation from 600 to 1100 meters, with various hills and mountains rising higher. The highest peak is Zomba Mountain at 2087 meters. The highlands are bounded on the west and south by the valley of the Shire River, an extension of the African Rift Valley. The Phalombe Plain slopes gently towards Lake Chilwa to the northeast, and separates the highlands from the taller Mulanje Massif to the east. Streams originating in the highlands drain west, south, and southeast towards the Shire River, or northeast into the closed basin of Lake Chilwa. The highlands have a cooler climate and more rainfall than the surrounding lowlands, and are home to distinct forests, woodlands, and grasslands that make up the South Malawi montane ...

Zimbabwe
Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona language, Shona, and Northern Ndebele language, Ndebele the most common. Beginning in the 9th century, during its late Iron Age, the Bantu peoples, Bantu people (who would become the ethnic Shona people, Shona) built the city-state of Great Zimbabwe which became one of the major African trade centres by the 11th century, controlling the gold, ivory and copper trades with the Swahili coast, which were connected to Arab and Indian states. By the mid 15th century, the city-state had been abandoned. From there, the Kingdom of Zimbabwe was established, fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bambusa
''Bambusa'' is a large genus of clumping bamboos. Most species of ''Bambusa'' are rather large, with numerous branches emerging from the nodes, and one or two much larger than the rest. The branches can be as long as 11 m (35 ft). They are native to Southeast Asia, South Asia, China, Taiwan, the Himalayas, New Guinea, Melanesia, and the Northern Territory of Australia. They are also reportedly naturalized in other regions, e.g. Africa, Americas, and various oceanic islands.

Malawi
Malawi (; or aláwi Tumbuka: ''Malaŵi''), officially the Republic of Malawi, is a landlocked country in Southeastern Africa that was formerly known as Nyasaland. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south and southwest. Malawi spans over and has an estimated population of 19,431,566 (as of January 2021). Malawi's capital (and largest city) is Lilongwe. Its second-largest is Blantyre, its third-largest is Mzuzu and its fourth-largest is its former capital, Zomba. The name ''Malawi'' comes from the Maravi, an old name for the Chewa people who inhabit the area. The country is nicknamed "The Warm Heart of Africa" because of the friendliness of its people. The part of Africa now known as Malawi was settled around the 10th century by migrating Bantu groups . Centuries later, in 1891, the area was colonised by the British and became a protectorate of the United Kingdom known as Nyasaland. In 1953, it became ...

Mozambique
Mozambique (), officially the Republic of Mozambique ( pt, Moçambique or , ; ny, Mozambiki; sw, Msumbiji; ts, Muzambhiki), is a country located in southeastern Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. The sovereign state is separated from the Comoros, Mayotte and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Notably Northern Mozambique lies within the monsoon trade winds of the Indian Ocean and is frequentely affected by disruptive weather. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and language. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of t ...
