The Ea land type in the Newcastle–Memel–Chelmsford Dam area is underlain by dolerite. A numerical classification (Twinspan) was applied to total floristic composition data from 58 sample plots surveyed in this land type. The resulting classification was refined by Braun-Blanquet procedures. Four major vegetation types, namely hygrophilous vegetation, grassland, woodland and dry forest, are recognized. These were divided into 12 plant communities which were hierarchically classified, described and ecologically interpreted.
Die Ea landtipe in die Newcastle–Memel–Chelmsforddam omgewing word deur doleriet onderlê. ’n Numeriese klassifikasie (Twinspan) van die data van die totale floristiese samestelling van 58 monsterpersele in hierdie landtipe is uitgevoer. Die resultaat is deur middel van Braun-Blanquet prosedures verfyn. Vier hoofplantegroeitipes, naamlik higrofiliese plantegroei, grasveld, boomveld en droë woud, is onderskei. Hierdie plantegroeitipes is in 12 plantgemeen-skappe verdeel en word hiërargies geklassifiseer, beskryf en ekologies geïnterpreteer.
