Wetland vegetation in the North-eastern Sandy Highveld, Mpumalanga, South Africa

Abstract

The wetland vegetation of the high mountain grasslands of Mpumalanga w as sampled by using stratification based on geology and land types. Floristic data were classified by TWINSPAN procedures and refined by using the Braun-Blanquet method. This resulted in the recognition of four major w etland plant communities w hich are subdiv ided into eleven minor plant communities. The major communities include the Phragmites australis Wetland occurring in relatively deep water, the  Miscanthus junceus Wetland from moist river banks and wet drainage lines, the  Eragrostis biflora-Stihurus allopecuroides Moist Grassland restricted to moist, poorly drained soils w ith a high water table, and Arundinella nepalensis Moist Grasslands on black vertic soils.
