Disturbance is essential to maintain this open vegetation type and its species richness.
On the Sandstone and Manganese ares the stable state of the vegetation is likely to be composed of the Australian element of the vegetation modified to various extents by fire.
An appreciation of this geomorphic complexity, which is typical in arid environments, is critical to the understanding of vegetation patterns on alluvial fans.
The propagation of numerous cryptogams on fixed sand surface and the colonization of annual and perennial plant species promoted the succession and restoration of the vegetation towards herb-dominated vegetation, which are similar to the primary vegetation types of the adjacent steppified desert and desert steppe.
This is the first report on the phytosociology of this vegetation association.
The method is readily applicable to other vegetation types.
Vegetation has strong seasonality in the analysed area.
Vegetation structure is associated to geomorphologic heterogeneity.
The obvious vegetation heterogeneity in the still active sand-blown area is related to differences in timing of vegetation establishment on particular relief types, thus the succession exhibits a terrain-dependent asynchronous character.
The plant diversity of the various vegetation types in the area is related to the duration of colonization of the vegetation type, the extent of disturbance by human beings, and the physical structure diversity of the vege...
Ordination of the data and biplot analysis showed that the vegetation is influenced by anthropogenic factors and altitudinal variation.
It is suggested that, over time, the vegetation c...
One possible source could be the characterization of the vegetation.
A few species may be indicators of vegetation types.
An assessment was made to relate the vegetation types to various phytochoria and it is concluded that the Bankenveld has definite floristic affinities to the grassland of the interior plateaux of South Africa, the savannas of the Sour Bushveld and Sourish Mixed Bushveld, the Drakensberg Afromontane vegetation and the Kalahari vegetation.
