The Sahel region or Sahelian acacia savanna is a biogeographical region in Africa. It is the transition zone between the more humid Sudanian savannas to its south and the drier Sahara to the north. The Sahel has a hot semi-arid climate and stretches across the southernmost latitudes of North Africa between the Atlantic Ocean and the Red Sea. Although geographically located in the tropics, the Sahel does not have a tropical climate.
Brachystegia tamarindoides, known as mu'unze and also as the mountain acacia, is a medium-sized tree with smooth grey bark, bluish-green leaves and small creamy-white flowers that produce copious amounts of pollen and nectar. It is almost always very close to upturned umbrella shaped with a partially developed flat top, making it easy to recognise in mixed woodland. In this it differs from most of the other Brachystegia species that have variable shapes. The leaves are feathery in appearance, with around 10-12 leaflets arrayed along each leaf stalk.
Colophospermum mopane, commonly called mopane, mopani, balsam tree, butterfly tree, or turpentine tree, is a tree in the legume family (Fabaceae), that grows in hot, dry, low-lying areas, 200 to 1,150 metres in elevation, in the far northern parts of Southern Africa. The tree only occurs in Africa and is the only species in genus Colophospermum. Its distinctive butterfly-shaped (bifoliate) leaf and thin seed pod make it easy to identify. In terms of human use it is, together with camel thorn and leadwood, one of the three regionally important firewood trees.
Grevillea robusta, commonly known as the southern silky oak, silk oak or silky oak, silver oak or Australian silver oak, is a flowering plant in the family Proteaceae, and accordingly unrelated to true oaks, family Fagaceae. Grevillea robusta is a tree, and is the largest species in its genus. It is a native of eastern coastal Australia, growing in riverine, subtropical and dry rainforest environments.
Vachellia tortilis, widely known as Acacia tortilis but now attributed to the genus Vachellia, is the umbrella thorn acacia, also known as umbrella thorn and Israeli babool, a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa, but also occurring in the Middle East.
Acaciella angustissima is most recognized for its drought tolerance and its ability to be used as a green manure and ground covering. It is a perennial, deciduous, and belongs to the family Fabaceae (beans/legumes) and as it grows it starts as a shrub but eventually matures to a small tree. The tree has a high density of leaves along with small clumps of white flowers and creates 4–7 cm long seed pods. Acaciella angustissima is found in tropical areas around the equator since, its water needs can vary from 750 to 2,500 mm a year. It has an advantage it can withstand a moderate drought, since its leaves are retained even in long dry periods. Aside from being drought tolerant, Acaciella angustissima also has the benefit of being a green manure, since it has such a high leaf density, but also loses the majority of its leaves each season. So the leaves can be used in composting or can be saved and used as livestock feed. It should only be used as an additive to the feed and not the main source, since it also toxic in high doses.
Vachellia nilotica, more commonly known as Acacia nilotica, and by the vernacular names of gum arabic tree, babul, thorn mimosa, Egyptian acacia or thorny acacia, is a flowering tree in the family Fabaceae. It is native to Africa, the Middle East and the Indian subcontinent. It is also considered a 'weed of national significance' and an invasive species of concern in Australia, as well as a noxious weed by the federal government of the United States.
Vachellia karroo, commonly known as the sweet thorn, common acacia, Karoo thorn, Cape gum or cockspur thorn, is a species of Vachellia, in the Mimosa sub-family (Mimosoideae) of the Fabaceae or pea family, which is native to southern Africa from southern Angola east to Mozambique, and south to South Africa.
Vachellia sieberiana, until recently known as Acacia sieberiana and commonly known as the paperbark thorn or paperbark acacia, is a tree native to southern Africa and introduced into Pakistan. It is used in many areas for various purposes. The tree varies from 3 to 25 m in height, with a trunk diameter of 0.6 to 1.8 m. It is not listed as being a threatened species.
Farmer-managed natural regeneration (FMNR) is a low-cost, sustainable land restoration technique used to combat poverty and hunger amongst poor subsistence farmers in developing countries by increasing food and timber production, and resilience to climate extremes. It involves the systematic regeneration and management of trees and shrubs from tree stumps, roots and seeds. FMNR was developed by the Australian agricultural economist Tony Rinaudo in the 1980s in West Africa. The background and development are described in Rinaudo's book The Forest Underground.
Vachellia xanthophloea is a tree in the family Fabaceae, commonly known in English as the fever tree. This species of Vachellia is native to eastern and southern Africa. It has also become a landscape tree in other warm climates, outside of its natural range.
The wildlife of Zimbabwe occurs foremost in remote or rugged terrain, in national parks and private wildlife ranches, in miombo woodlands and thorny acacia or kopje. The prominent wild fauna includes African buffalo, African bush elephant, black rhinoceros, southern giraffe, African leopard, lion, plains zebra, and several antelope species.
The wildlife of Mozambique consists of the flora and fauna of this country in southeastern Africa. Mozambique has a range of different habitat types and an ecologically rich and diverse wildlife. This includes 236 species of mammal, 740 species of bird and 5,692 species of vascular plant. The Maputaland-Pondoland-Albany hotspot, with significantly high levels of biodiversity, stretches from the southern tip of Mozambique into northeastern South Africa.
Baikiaea is a genus of flowering plants in the legume family, Fabaceae. It includes six species of trees native to sub-Saharan Africa. Species range from Nigeria eastwards to Uganda and Tanzania and south to Zimbabwe, Botswana, and Namibia. Habitats range from lowland tropical rain forest to seasonally dry forest and woodland or savannas on well-drained soils.
Dichrostachys cinerea, known as sicklebush, Bell mimosa, Chinese lantern tree or Kalahari Christmas tree, is a legume of the genus Dichrostachys in the family Fabaceae.
Parkia biglobosa, known in English as the African locust bean, is a perennial deciduous tree in the family Fabaceae. It is found in a wide range of environments in Africa and is primarily grown for its pods that contain both a sweet pulp and valuable seeds. Where the tree is grown, the crushing and fermenting of these seeds constitutes an important economic activity. Various parts of the locust bean tree are used for medicinal and food purposes. As a standing tree, locust bean may have a positive effect on the yield of other nearby crops.
Balanites aegyptiaca is a species of tree, classified as a member of either the Zygophyllaceae or the Balanitaceae. This tree is native to much of Africa and parts of the Middle East.
Fertilizer trees are used in agroforestry to improve the condition of soils used for farming. As woody legumes, they capture nitrogen from the air and put it in the soil through their roots and falling leaves. They can also bring nutrients from deep in the soil up to the surface for crops with roots that cannot reach that depth. Fertilizer trees are further useful for preventing fertilizer erosion, soil degradation and related desertification, and improving water usage for crops.
The Zambezian and mopane woodlands is a tropical and subtropical grasslands, savannas, and shrublands ecoregion of southeastern Africa.
