Angolan Wet Miombo Woodlands
Angolan miombo woodlands cover most of central Angola and extend into the Democratic Republic of Congo. They are part of the larger miombo ecosystem that covers much of eastern and southern Africa. Location and description This area of savanna and woodland covers an area of plateau and gentle hills in central Angola, in the Cubango-Zambezi Basin which drains into the Zambezi River to the east. The area lies east of the range of hills that parallel the Atlantic coast and north of the Kalahari Desert reaching up as far as the rainforests of the Congo. Climate The Angolian miombo woodlands has a tropical climate, wetter than the surrounding savanna, with most of the rain falling in the hotter summer months (November–March). Flora The flora is moist deciduous broadleaf savanna and woodland. Between these areas is open grassland. Three species of tree dominate miombo woodland: ''Brachystegia'', '' Julbernardia'', and '' Isoberlinia''. Under the trees there is a rich variety of oth ...

Fauna
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and '' funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the " Sonoran Desert fauna" or the " Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word fo ...

Isoberlinia
''Isoberlinia'' is a genus in the family Fabaceae of five species of tree native to the hotter parts of tropical Africa. They are an important component of miombo woodlands. The leaves have three or four pairs of large leaflets and stout seed pods. Some former species in this genus were transferred to the genus '' Julbernardia''. References * Binns, Blodwen. (1972).

Brachystegia
''Brachystegia'' is a genus of tree of the subfamily Detarioideae that is native to tropical Africa. Trees of the genus are commonly known as miombo, and are dominant in the miombo woodlands of central and southern tropical Africa. The Zambezian region is the centre of diversity for the genus.Emmanuel N. Chidumayo and Davison J. Gumbo, eds. (2010). ''The dry forests and woodlands of Africa: managing for products and services''. Earthscan, 2010. Description Hybridisation between the species occurs and taxa show considerable variation in leaflet size, shape and number, making identification difficult. New leaves show a great range of red colours when immature, later turning to various shades of green. Range and habitat ''Brachystegia'' species range from coastal West Africa through Nigeria and Central Africa to the Northern Province of South Africa. Habitats include seasonally dry forest, woodland, wooded grassland and bushland, and lowland tropical rain forest, often along ri ...

Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessm ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...

Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ...

Flora
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora (mythology), 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 ...

Tropical Climate
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. Tropical climates are defined by a monthly average temperature of or higher in the coolest month, featuring hot temperatures and high humidity all year-round. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm but may have seasonal dryness to varying degrees. There are normally only two seasons in tropical climates, a wet (rainy/monsoon) season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense in these climates. There are three basic types of tropical climates within the tropical climate group: tropical rainforest climate (Af), tropical monsoon climate (Am) and Tropical savanna climate, tropical savanna or tropical wet and dry climate (Aw for dry winters, and As for dry summers), which are classified and distinguished by the precipitation levels of the ...

Kalahari Desert
The Kalahari Desert is a large semiarid climate, semiarid sandy savanna in Southern Africa covering including much of Botswana as well as parts of Namibia and South Africa. It is not to be confused with the Angolan, Namibian, and South African Namib coastal desert, whose name is of Khoekhoe language, Khoekhoegowab origin and means "vast place". Etymology ''Kalahari'' is derived from the Tswana language, Tswana word ''Kgala'', meaning "the great thirst", or ''Kgalagadi'', meaning "a waterless place"; the Kalahari has vast areas covered by red sand without any permanent surface water. History The Kalahari Desert was not always a dry desert. The fossil flora and fauna from Gcwihaba, Gcwihaba Cave in Botswana indicates that the region was much wetter and cooler at least from 30 to 11 thousand Before Present, especially after 17,500 BP. Geography Drainage of the desert is by dry black valleys, seasonally inundated pans, and the large salt pan (geology), salt pans of the Mak ...
