Maputaland-Pondoland-Albany Hotspot

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.[1] 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 (known as Swaziland until 2018) and into southern Mozambique and Mpumalanga. The Maputaland Centre of Plant Endemism is contained in northern KwaZulu-Natal and southern Mozambique.

Geography

This ecoregion covers globally all the humid subtropical climate zones of Africa (the latter being located almost exclusively in South Africa), an area of 274,136 km2 (105,845 sq mi). It forms a broad coastal strip extending from the extreme south of Mozambique and north-east of Mpumalanga to the east of Eastern Cape Province in South Africa, including the Wild Coast. It also includes eastern Swaziland and borders southern and eastern Lesotho. It consists of three regions more or less biologically close but each with its own characteristics. Maputaland (also known as Tongaland) refers to the southern part of Mozambique, Swaziland and northern KwaZulu-Natal, Pondoland includes central and southern KwaZulu-Natal, and Albany is the eastern part of Eastern Cape.[2]

The terrain in this region is complex, providing a great diversity of landscapes with varied reliefs. It encompasses the southeast of the Great Escarpment and down to the edge of the Indian Ocean. As a result, this ecoregion includes much of the Drakensberg range, especially in the south and centre of the area. One of the best-watered areas in South Africa, a large part of the area receives on average between 750 and 1,000 mm (30 and 39 in) per year and the Kwazulu-Natal coasts as well as parts of the Drakensberg exceed the annual 1,000 mm (39 in).[3] The northern part of the area consists mainly of medium and lowland plains with areas of ancient sand dunes, while the southern part has more rugged terrain with many cliffs cut by multiple streams. Inland, there are several ranges of mountain which include Sneeuberge, Winterberg, Amathole Mountains, Ngeli Range, Lebombo Mountains and Ngoye Range.[4]

Biodiversity

The vegetation cover is mainly composed of forests, shrubland, bushveld and meadows. About 80% of the remaining forests of South Africa occur in this region, and nearly 600 species of trees are represented here, the highest diversity of any temperate forest in the world. Among the large number of plants in this ecoregion, about 1900 are endemic. The Albany region also has a great diversity of succulent plants, notably arborescent plants, differing from the leafy succulent species of the Karoo desert.[4]

Although the hotspot was originally envisaged as referring to the wide diversity of vascular plant species, the pattern of plant endemism is matched by numerous endemic vertebrates. The degree of endemism among plants in this hotspot is 23.5% whereas the degree of endemism among vertebrates is 5.1% and near-endemism 4.9%. If the area of the hotspot was redefined as the "Greater Maputaland-Pondoland-Albany" area, an increase of 73%, to include the Great Escarpment area, the vertebrate endemism would total 146 species (19 freshwater fishes, 29 amphibians, 75 reptiles, 15 birds and 8 mammals), a figure 135% higher than the 62 vertebrate species for the MPA as presently defined.[5]

Most of the endemic vertebrates in the ecoregion inhabit the forests and grasslands, and many have niche habitat requirements such as rocky outcrops or marshy areas within these larger biomes; the Sloggett's vlei rat and the Natal red rock hare are quite widespread in the area while the woodbush legless skink and the robust golden mole have narrower habitat requirements.[6]
