Abstract

The vegetation of Chirinda Forest boundary was classified into eight types using Two-way Indicator Species Analysis (TWINSPAN) and Detrended Correspondence Analysis (DCA). The moist forest comprises three types:  Strychnos mellodora-Chrysophyllum gonmgosanum Forest on deep dolerite soils; Chrysophyllum gorungosanum-Myrianthus holstii Forest on shallow dolerite soils; and  Teclea iiobilis-Ehretia cymosa Forest on drier, but deep dolerite soils. The non-forest vegetation comprises five types: Themeda triandra Grassland on shallow dolerite soils; Psidium guajava Bushland on sandstone; Bridelia micrantha-Harungana madagascariensis Mixed Woodland not restricted to any one particular soil type; Acacia karroo- Heteropyxis dehniae Woodland on shallow soils derived from sandstone but sometimes on dolerite; and  Julbemardia globiflora-Brachystegia spiciformis (Miombo) Woodland on sandstone.
