Aspects of coastal fynbos phenology
… phenology of several south western Cape coastal fynbos species, with a general introduction and conclusion I inking the three. The introduction discusses factors relating to the occurrence of summer growth in some Australian heath and Cape fynbos species. The first paper deals with the responses …

Remote sensing of water stress in fynbos vegetation
… method for determining drought stress in Fynbos vegetation. I hypothesize that (1) water stress in fynbos is detectable with the use of a remote sensing index, namely NDVI and (2) that the remotely sensed trends will correlate with ground truth measures of water stress.

Mist interception by three species of mountain fynbos
… was to investigate mist interception by Mountain Fynbos under non-rainfall conditions. Quantitative measurements and qualitative observations of plant-drip and stem-flow from selected plant species were recorded at five experimental sites on the Back Table of Table Mountain, Cape Province. …

The implications of fynbos phytogeography for wetland photoassessment
… condition of lowland wetlands in the Fynbos biome of the South Western Cape of South Africa. A field survey and analysis of freshwater wetland vegetation across the Cape coastal lowlands (below 200m a.s.l.) was undertaken in the present study to explore the potential to identify …

Distribution of phosphorus in sandy soils of coastal fynbos
The levels of soil phosphorus (both total and plant available) were investigated at the Pella intensive study site and were found to be low. Resin extractable phosphorus fluctuated seasonally, peaking at the soil surface during summer and declining to a minimum in the winter months. Rates of …

The effects of recent landuse on a fynbos site
Landuse from 1920 to 1981 on the Fynbos Biome Research site at Pella, approximately 40 kilometres north of Cape Town, South Africa, and its immediate environs was studied to investigate possible causal relationships between Landuse and management practices and the resultant ecosystem. Fire has …

Preburnt and postburnt fynbos standing crop at Pella, Cape
At Pella research station , 20 year-old fynbos standing crop was determined by cropping eight 2m x 2m plots and felling five Protea repens trees in an unburnt area . A regression was also performed between the dry mass of the P. reopens trees (kg) and their stem diameter (cm). It was estimated that …

Sand plain fynbos conservation : the Kenilworth Racecourse case study
The current extent of Sand Plain Fynbos and threats to its survival are examined, with a view to proposing effective means of managing areas of high conservation priority. Extensive depletion of Sand Plain Fynbos has resulted from agricultural development, urbanisation and its susceptibility to …

Aspects of the structure and phenology of two fynbos communities
… mediterranean environments. Taxa typical of the fynbos flora are dominant in both communities, but the drier Cedarberg community has fewer species in these taxa and more annuals than the moister Kogelberg environment. These floristic changes are reflected also in the growth form spectra and the …

Enhancement of the Fynbos Leaf Optical Recognition Application (FLORA-E)
… and developing an artificially intelligent Fynbos Leaf Optical Recognition Application (FLORA) platform. Previous versions of FLORA (versions A through D) were designed to recognise Proteaceae fynbos leaves by extracting six digital morphological features, then using the k-nearest neighbour …

Ecological differentiation and the evolution and maintenance of fynbos diversity
… Here I investigate these processes in the Cape fynbos of South Africa by examining the diversification, biogeography and community assembly of a clade of reticulate-sheathed Tetraria species (Cyperaceae:Schoeneae).

Vegetation studies in the Humansdorp region of the Fynbos Biome
… forest) in the Humansdorp region of the Fynbos Biome. The first paper is a re-evaluation of vegetation concepts in the study area and, more generally, in the Fynbos Biome and adjacent biomes. Syntaxa are characterized in terms of floristics (including biogeographical affinities and …

Comparative water relations of indigenous and invasive Australian Proteaceae in fynbos
… was compared between co-occurring indigenous fynbos proteoids and invasive Australian hakeas H. sericea, H. gibbosa and H. suaveolens. At the driest site, H. suaveolens was slightly more WUE than several co-occurring proteoids; there was no significant difference between hakeas and proteas at …

The ecology of sprouting in South African forests, savannas and fynbos
… with the ecology of sprouting in forests, fynbos and savannas respectively; and the fourth undertakes to determine whether sprouting is considered in plant ecological strategy schemes. Chapter 1 and 2 deals with the role of sprouting in forests in relation to reseeding as key regeneration …

Flammability traits of fynbos species with different post-fire regeneration strategies
… to it is investigated in 15 co-occurring fynbos and forest species with burning experiments performed at Bain's Kloof Pass, Western Cape of South Africa. Eight species are characterised by fire-stimulated (mostly seeders) and seven by non-fire-stimulated recruitment (mostly resprouters). …

Phytogeography, endemism and diversity of the fynbos of the southern Langeberg
… endemism and species diversity in the rich fynbos flora of the southern Lange berg, Cape, South Africa. The basis was a survey of the fynbos vegetation of the southern Langeberg carried out following the Braun-Blanquet or Zurich-Montpellier approach. Forty-six plant communities were …
