Amphibious Vegetation in the Afro-Alpine Belt and the Role of Cryoturbation in Creating Regeneration Niches

The wetland vegetation of the Afro-(sub)alpine belt, which is dominated by tussock grassland, has embedded in it ericaceous shrubs, Helichrysum cushions and Carex bogs, which constitute small microhabitats with annuals. A synopsis of these annual turfs is presented in a constancy table, based upon the available plot data (168 releves), sampled on the tops of the high volcanoes of East Africa (3500–4500 m altitude). The results are compared with similar vegetation types in the Ethiopian Highlands, Drakensberg Mts. and Marion Island (South Africa).
