The vegetation ecology of the Eastern Transvaal Escarpment in the Sabie area. 3. Annotated checklist

Abstract

Over 1 000 plant taxa occumng in a 1 300 km; belt transect extending from Hazyview (530 m elevation) to Mount Anderson (2 280 m elevation) in the Sabie area of the Eastern Transvaal Escarpment are listed by genus, with species arranged alphabetically within genera. Annotations include genus author, species author, growth form, habitat, collector and specimen number Floristic analysis shows the Asteraceae as representing the largest family, followed by the Fabaceae. Poaceae. Rubiaceae and Liliaceae Flonstic affinities are briefly discussed. UITTREKSELIn 'n 1 300 km2 breé lynopname. wat vanaf Hazyview (530 m bo seespieël) tot Mount Anderson (2 280 m bo seespieël) in die Sabie-area van Oos-Transvaalse platorand strek. kom meer as 1 000 planttaksons voor wat volgens genus gelys is. Die spesies is alfabeties onder die genusse gerangskik Aantekeninge sluit die genus-outeur. spesie-outeur. groeivorm. habitat, versamelaar en eksemplaamommer in. Volgens die floristiese analise verteenwoordig die Asteraceae die grootste familie gevolg deur Fabaceae. Poaceae. Rubiaceae en Liliaceae Floristiese verwantskappe word ook kortliks bespreek.

The vegetation ecology of the Eastern Transvaal Escarpment in the Sabie area. 2. Floristic classification

“…The quadrats were distributed as follows: 46 in forest, 64 in thicket, 76 in woodland, nine in shrubland and 56 in grassland [physiognomy based on Edwards's (1983) formation classes]. In each quadrat, all plant species were listed together with their Domin-Krajina cover-abundance values and growth forms (Deall 1985). The total canopy cover and estimated height range of each stratum of vegetation was also (vi) Lithology (field nomenclature), based on the stratigraphic classification for South Africa (SACS 1980), as adapted by .…”

“…By means of selected programs in PHYTOTAB (Westfall et al 1982), a provisional phytosociological classification was made on the basis of the entire data set (251 relevés and 1 043 species, including unidentified specimen numbers). Four data subsets were then identi fied on the basis of floristic and environmental disconti nuity (Deall 1985). Species in each subset were then reclassified within the confines of their subset distribu tion (Coetzee 1983).…”

“…Both non-differential species and species-groups defining more than a single syntaxon were also removed*. Syntaxa were reduced to single columns by transforming the cover-abundance values of differential species to constancy values thereby creating synoptic tables (Deall 1985).…”

The Flora of the Drakensberg Alpine Centre

“…The numbers of Cape elements in each high-altitude flora were derived from inventories of their constituent taxa: Nyika (C. Willis et al, unpublished data); Mt. Mulanje (Whyte, 1894;Chapman & White, 1970);Chimanimani (Phipps & Goodier, 1962;Wild, 1964Wild, , 1968; Wolkberg Centre ( Van der Schijff & Schoonraad, 1971;Deall & Backer, 1989;Matthews et al, 1993;Stalmans et al, 1997); DAC (Carbutt & Edwards, 2001, and this study); KwaZulu-Natal Drakensberg, Eastern Cape Drakensberg and Sneeuberge (all from PRECIS).…”

Vegetation of the rock habitats of the Sekhukhuneland Centre of Plan Endemism, South Africa

“…Although several phytosociological studies have been conducted on vegetation types o f the north east ern D rakensberg Escarpm ent and adjacent areas of Lim popo [Northern Province] and M pum alanga (Deall 1985;Bloem 1988;M atthews 1991;Burgoyne 1995), the vegetation o f the Sekhukhuneland Centre o f Plant Endem ism (SCPE) (Van Wyk & Smith 2001; has never been studied in detail. Recently much work has been done to docum ent the plant diversity and vegetation o f this poorly known m icro-regional Centre of Plant Endemism (Siebert et al 2002a-e;Siebert et al 2003).…”
