  Afromontane - Wikipedia, the free encyclopedia
The tree genera Afrocrania, Balthasaria, Curtisia, Ficalhoa, Hagenia, Kiggelaria, Leucosidea, Platypterocarpus, Trichocladus, Widdringtonia, and Xymalos are Afromontane endemics or near-endemics, as are the plant genera Ardisiandra, Cincinnobotrys, and Stapfiella.
The Afromontane forests occur along the mountainous arc of the Drakensberg Range, from Limpopo Province in the northeast to the Western Cape Province in the southwest.
The Afromontane forests are intolerant of fire, and the frequent fires of the surrounding fynbos, savanna, and grassland limit the expansion of the forests.

 Afromontane Forest
Afromontane Forest reaches its greatest stature in the Tsitsikamma region from where it extends to Knysna.
However, Afromontane Forest would certainly spread into both grasslands and Fynbos were it not for fires - all forest patches are in fire-safe habitats with the largest stands occurring in the moist valleys of the Garden Route where they are protected by the sea and the Cape Fold Belt mountains.
Afromontane Forest is well conserved in a number of areas, and many stands are safe from exploitation by their isolation in remote areas.

 BioMed Central | Full text | Preliminary inventory and classification of indigenous afromontane forests on the Blyde ...
The landscape is prone to lightning-induced burning [11] and is topographically complex, hosting a variety of habitats [12], including grassland plateaus, wetlands and sponge areas, grassland slopes, afromontane forest, riparian forest, moist woodlands, dry woodlands and shrublands.
According to Geldenhuys [5], conservation status implies the extent to which populations, species or communities have been modified by the influences of man and the degree to which they might be expected to maintain their genetic diversity and ecological processes in the medium term (10 to 100 years).
Two afromontane forest communities are recognized and associated along an altitudinal gradient, one within the moist mist belt and one within drier micro-climates outside the mist belt; further, within each community, variants were recognized based on either available soil moisture or degree of past utilization.

 Biodiversity Hotspots - Eastern Afromontane - Overview
The mountains of the Eastern Afromontane hotspot are scattered along the eastern edge of Africa, from Saudi Arabia in the north to Zimbabwe in the south.
The Eastern Afromontane Hotspot encompasses several widely scattered, but biogeographically similar mountain ranges in eastern Africa, from Saudi Arabia and Yemen in the north to Zimbabwe in the south.
The lower altitudinal limit is usually taken as between 1,500 and 2,000 meters, although this is lower away from the equator, while the Knysna Forests in the Cape, which are considered to be the southernmost reaches of the Afromontane habitat (though not included here), are at 300 meters.

 Knysna Elephant Park, Knysna, Plettenberg Bay, Garden Route, adventure safari South Africa
The Afromontane (meaning African mountain) forest is a plant community (biome) that does not strictly fall within the description of the Cape Floral Kingdom.
The forest can be further divided into different types, which follow the general rule-of-thumb that there is a greater diversity of species in the lower altitude forests than in those of the higher altitudes (this is also true for younger stands of forest, which generally have more species than the older forests).
The Afromontane forests are usually found at altitudes below 1 000 metres, in areas that are protected from wind and fire, and in soils that are deeper, more fertile, and more able to retain their moisture than those characteristic of the fynbos.

 Hotspots Revisited
The lower altitudinal limit is usually taken as between 1 500 and 2 000 m, although this is lower away from the equator, while the Knysna Forests in the Cape, which are considered to be the southernmost reaches of the Afromontane habitat, are at 300 m.
Far to the north, the Asir Mountains of southwest Saudi Arabia and the highlands of Yemen have biological affinities with the Eastern Afromontane Hotspot, being as they were at one stage part of the large Ethiopian dome that began to arise some 75 million years ago (Kingdon 1989).
The Drakensberg Range of South Africa and Lesotho (the high point being Thabana-Ntlenyana, 3 482 m), coupled with the Barberton, Wolkberg, Soutpansberg and perhaps Sekhukhuneland centers of endemism in southern Africa (Van Wyk and Smith 2001), form a similar high-altitude Afromontane outlier to the south, but are, for the moment, not included in the analysis.

 Biodiversity Hotspots - Eastern Afromontane - Human Impacts
The primary threat to the biodiversity of the Eastern Afromontane Hotspot is habitat loss, due to conversion of land for agriculture, plantations and commercial estates, as well as logging.
Intentional burning has been responsible for converting much of the Afromontane forests in the region to grassland and scrub-grassland.

The forest patches are restricted to the deep ravines or remote valleys of the highest mountains in the Huambo and Cuanza Sul provinces and an area of Afromontane forest mosaic further south, on the Serra da Chela in Huíla province.
Clearing for agriculture is probably the greatest threat to the Afromontane grasslands and savannas given the relatively high agricultural potential and the dense human population.
White (1983) mapped four areas of Afromontane vegetation in the Huambo and Cuanza Sul provinces and an area of Afromontane forest mosaic further south, on the Serra da Chela in the Huíla province.

 The Conservational Importance of the Mgwayiza Mist Belt Forest, Malolotja Nature Reserve, Swaziland   (Site not responding. Last check: 2007-10-26)
Some of the trees occurring in Afromontane forest are very old, more than a hundred years old, and consequently any damage or destruction of this habitat could take centuries for it to recover.
There is a transition from Afromontane forest, at 1400m, to Afrotropical forest and thicket at 680m, from the top of the Mgwayiza Range to the Nkomati River.
The forest is the finest example of fully protected Afromontane mist belt forest in which the diversity of bird species is almost beyond belief.

If one considers that Afromontane forests only occupy 0.47% of South Africa's land area, it brings home the fragility, conservation importance and uniqueness of this lovely botanical heritage.
Except for the coastal forests at Knysna, the Afromontane forests of the Magoebaskloof area rank as of the most extensive in South Africa and also of the most beautiful.
The vegetation of these forests have enormous plant diversity and are dominated by trees as tall as 30-40m.

 ePrintsUQ - Towards Sustainable Management: Southern Africa's Afromontane, and Western Australia's Jarrah Forests
Rather, in WA jarrah forests, amendments in purpose and tenure were subsequent to the loss of most mills and towns, while in southern Africa's Afromontane forests, timber workers were pensioned by 1939 because of scanty remaining merchantable timber.
In the jarrah forests, we believe that the conflict generated by conservation concerns, reduced timber industry employment, and reduced benefits flowing to the communities adjacent to the logged forests, has fueled dissatisfaction with forest management outcomes.
A sustainable management system appears to have been achieved in the Afromontane forests and has led to the development and maintenance of support for small-scale operations to supply local timber needs from State managed forests.

The present study focuses on the population dynamics and regeneration of an early successional shrub Dodonaea angustifolia and a late successional tree Olea europaea ssp.
Population structure and dynamics, regeneration and seed banks in dry Afromontane habitats were considered.
For both species, three population structure patterns were identified: 1) high density, reversed J-shape structure with many seedlings and few large individuals, 2) lower density, unimodal structure with higher proportions of plants of intermidiate size, 3) high density with higher proportions of large plants, in some cases bimodal with small and large individuals.

 CURRENT RESEARCH ISSUES AND PROSPECTS FOR CONSERVATION AND DEVELOPMENT
By taking Bwindi Impenetrable National Park and its Afromontane forest as a case-study, I am able to highlight the potential and many pitfalls of NWFPs which may not yet be evident in massive forested areas such as the Zaire basin or Amazonia where human population densities are 1-10 people/km².
Muir (1990), for example, working with local wood-cutters in Afromontane forest in southern Africa, has demonstrated that cultivating alternative sources of building material outside indigenous forest can be over ten times cheaper than the cost of an intensive monitoring programme for sustainable use of that resource.
This issue is most evident in Afromontane and coastal forest protected areas, which are small and are surrounded by high numbers of rural farmers.
