The Albany thickets is an ecoregion of dense woodland in southern South Africa, which is concentrated around the Albany region of the Eastern Cape (whence the region's name originates).
The thickets grow on well-drained sandy soils in the wide valleys of the Great Fish, Sundays and Gamtoos River in the Eastern Cape and, extending further northwest, in the valleys of the Cape Fold Belt. Thicket is vulnerable to fire and to grazing so has always been restricted to valley areas where these are less of a threat than on open plains. [1]
The climate is dry, especially as one proceeds inland, but the shady valleys are cooler than the surrounding terrain which is hot in summer, cold in winter and receives irregular rainfall.
The thickets contain many endemic plants, in particular succulent Euphorbia species and can be divided into three sections of varying habitat. The thicket is richest and most dense in the river valleys near the coast where it contains thorny shrubs with an undergrowth of creepers and succulent plants. As the river valleys climb inland and upstream the climate is drier and the vegetation less dense. Finally the shrubland in mountain valleys to the northwest consists of predominantly the porkbush (Portulacaria afra) and jade plant (Crassula ovata) succulents, along with boxthorn (Lycium austrinum), jacketplum (Pappea capensis), Euclea undulata , Rhigozum obovatum , aloes and Schotia afra . Along with the fynbos ecoregions the Albany thickets comprise the Cape Floristic Region.
Birds in this area include black goshawk, black-headed oriole and two species which are almost endemic to the Cape area, the orange-breasted sunbird and Cape siskin. There is one near-endemic mammal Duthie's golden mole (Chlorotalpat duthieae) and in the inland valleys, Addo Elephant National Park is home to African bush elephant (Loxodonta africana), black rhinoceros (Diceros bicornis) and antelopes such as bushbuck (Tragelaphus scriptus), grey rhebok (Pelea capreolus), mountain reedbuck (Redunca fulvorufula), common eland (Taurotragus oryx), greater kudu (Tragelaphus strepsiceros), red hartebeest (Alcelaphus buselaphus), Cape grysbok (Raphicerus melanotis) and common duiker (Sylvicapra grimmia).
A large part of the region has been converted for agriculture or reduced by grazing, especially by goats. This is a continuous threat especially in the river valleys near the coast, which are also vulnerable to clearance for urban areas and tourist resorts. Protected areas include Addo Elephant National Park near Port Elizabeth, the Groendal Wilderness Area near Uitenhage on the Swartkops River, and the Baviaanskloof Mega Reserve.
The Madagascar subhumid forests are a tropical moist broadleaf forest ecoregion that covers most of the Central Highlands of the island of Madagascar. They are included in the WWF's Global 200 list of outstanding ecoregions. Most of the original habitats have been lost due to human pressure.
Addo Elephant National Park is a diverse wildlife conservation park situated close to Gqeberha in South Africa and is one of the country's 20 national parks. It currently ranks third in size after Kruger National Park and the Kgalagadi Transfrontier Park.
The Maputaland-Pondoland bushland and thickets is one of the ecoregions of South Africa. It consists of the montane shrubland biome.
The Kwazulu-Cape coastal forest mosaic is a subtropical moist broadleaf forest ecoregion of South Africa. It covers an area of 17,800 square kilometers (6,900 sq mi) in South Africa's Eastern Cape and KwaZulu-Natal provinces.
The Maputaland coastal forest mosaic is a subtropical moist broadleaf forest ecoregion on the Indian Ocean coast of Southern Africa. It covers an area of 29,961 square kilometres (11,568 sq mi) in southern Mozambique, Eswatini, and the KwaZulu-Natal Province of South Africa. Mozambique's capital Maputo lies within the ecoregion.
The Madagascar spiny forests is an ecoregion in the southwest of Madagascar. The vegetation type is found on poor substrates with low, erratic winter rainfall. The ecoregion contains an outstanding proportion of endemic plant species and is listed as one of the 200 most important ecological regions in the world; one of the Global 200.
The Succulent Karoo is a ecoregion defined by the World Wide Fund for Nature to include regions of desert in South Africa and Namibia, and a biodiversity hotspot. The geographic area chosen by the WWF for what they call 'Succulent Karoo' does not correspond to the actual Karoo.
The Eastern miombo woodlands (AT0706) are an ecoregion of grassland and woodland in northern Mozambique, southern Tanzania, and southeastern Malawi.
The wildlife of South Africa consists of the flora and fauna of this country in southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 858 species of bird and over 20,000 species of vascular plants.
The Mediterranean Acacia-Argania dry woodlands and succulent thickets is a Mediterranean forests, woodlands, and scrub ecoregion in North Africa centered mainly on Morocco but also including northwestern Western Sahara and the eastern Canary Islands.
Angolan mopane woodlands are situated in southwestern Angola, extending into northern Namibia. This ecosystem surrounds Etosha Pan, which is considered a separate ecoregion. The mopane trees are the main type of vegetation.
The Angolan Scarp savanna and woodlands is an ecoregion located on the coast of Angola, an area with a variety of habitats and rich in wildlife including many endemic birds and animals.
The Hobyo grasslands and shrublands is a desert and xeric scrubland ecoregion in Somalia. The ecoregion includes a belt of coastal dunes, 10 to 15 km wide, along the Indian Ocean coast, extending from north of Hobyo to south of Mogadishu.
The Maputaland-Pondoland-Albany Hotspot (MPA) is a biodiversity hotspot, a biogeographic region with significant levels of biodiversity, in Southern Africa. It is situated near the south-eastern coast of Africa, occupying an area between the Great Escarpment and the Indian Ocean. The area is named after Maputaland, Pondoland and Albany. It stretches from the Albany Centre of Plant Endemism in the Eastern Cape Province of South Africa, through the Pondoland Centre of Plant Endemism and KwaZulu-Natal Province, the eastern side of Eswatini and into southern Mozambique and Mpumalanga. The Maputaland Centre of Plant Endemism is contained in northern KwaZulu-Natal and southern Mozambique.
Portulacaria afra is a small-leaved succulent plant found in South Africa. These succulents commonly have a reddish stem and leaves that are green, but also a variegated cultivar is often seen in cultivation. They are simple to care for and make easy houseplants for a sunny location. In frost-free regions they may be used in outdoor landscaping.
Mediterranean forests, woodlands, and scrub is a biome defined by the World Wide Fund for Nature. The biome is generally characterized by dry summers and rainy winters, although in some areas rainfall may be uniform. Summers are typically hot in low-lying inland locations but can be cool near colder seas. Winters are typically mild to cool in low-lying locations but can be cold in inland and higher locations. All these ecoregions are highly distinctive, collectively harboring 10% of the Earth's plant species.
The Mandara Plateau mosaic, also known as the Mandara Plateau woodlands, is a tropical grasslands, savannas, and shrublands ecoregion located in the Mandara Mountains of northern Nigeria and Cameroon.
The Gouritz Cluster Biosphere Reserve is located in the Western Cape of South Africa. It is the 7th and largest of South Africa’s biosphere reserves; divided into four connected sectors ranging from sea level to 2,240 metres. The area is the only place in the world where three recognised biodiversity hotspots converge. The site is characterised by high endemism of plant species and threatened invertebrates including seven endemic species of the enigmatic beetle genus Colophon and 14 butterfly species. It provides a migratory route for large mammals such as the leopard and serves as a nursery for marine species.
The Albany Centre of Plant Endemism is situated in the coastal region of South Africa at the eastern end of the Eastern Cape Province. It is named after the district of Albany and falls within the Maputaland-Pondoland-Albany Hotspot. It is notable for its biodiversity and unique, endemic flora and fauna.
The Indian Ocean coastal belt is one of the nine recognised biomes of South Africa. They are described in terms of their vegetation and climatic variations.
