We explore the effect of post—fire microsites on seed and seedling distribution hence their potential role in community restoration. A summer wildfire control burn a sclerophyll shrubland mediterranean Australia produced mosaics physically chemically contrasting litter sand. Most seeds (>75%) all species released from burnt canopies fell, or were redispersed by wind, into patches after both fires. Data microsite characteristics wind exposure (fire intensity), height fruits, time release,...

(1) Production, nitrogen and phosphorus return, decomposition of leaf litter the invasive alien, Acacia saligna, was compared with that indigenous sclerophyllous shrub, Leucospermum parile, in sand-plain lowland fynbos acid soils low P during early stages alien invasion. The same done for A. cyclops Pterocelastrus tricuspidatus strandveld alkaline high P. (2) spp. had twice N concentrations species, whereas were highest species. (3) tended to produce more litter, three times content No...

This review provides an overview of the use remote sensing data, development spectral reflectance indices for detecting plant water stress, and usefulness field measurements ground-truthing purposes. Reliable stress over large areas are often required management applications in fields agriculture, forestry,conservation land rehabilitation. The technologies data determining spatial patterns is widely described scientific literature. Airborne, space-borne hand-held commonly used to investigate...

Land-cover change and habitat loss are widely recognised as the major drivers of biodiversity in world. maps derived from satellite imagery provide useful tools for monitoring land-use land-cover change. KwaZulu-Natal, a populous yet biodiversity-rich province South Africa, is one first provinces to produce set three directly comparable (2005, 2008 2011). These were used investigate systematic changes occurring with focus on conservation. The Intensity Analysis framework was analysis this...

Serotiny is the prolonged storage of seeds in closed cones or fruits held within crown woody plants. It widespread throughout fireprone vegetation with a predominantly winter rainfall, especially Mediterrnanean-type ecosystems (MTEs). Nonstorage feature summer-dominant rainfall nonfireprone vegetation. confers fitness benefits on an individual when fire return intervals fall between age to reproductive maturity and plant life span. The level serotiny species varies greatly along continuum...

SUMMARY (1) The phosphorus composition of the main soils dominant vegetation categories fynbos biome, south-western Cape, South Africa was studied. (2) Total, Bray No. 2 and resin-extractable phosphorus, pH organic matter varied significantly between with Fernwood strandveld containing highest total (338-422 ,ug g-' dry mass) (13-40 ug gdry concentrations. (3) Organic only 10-15% in but 58-77% other categories. (4) On west coast, a gradient soil texture, bulk density status occurred along...

Abstract Land‐use and cover changes around Budongo Forest Reserve (BFR) were analysed from multi‐temporal LandSat images (1988 2002) associated field‐based studies in 2003–2004. Three major land‐use classes: forest/woodland, sugarcane plantations grassland/shifting‐cultivation/settlements clearly discriminated. The area under cultivation increased over 17‐fold, 690 ha 1988 to 12729 2002, with a concomitant loss of about 4680 (8·2 per cent) mainly on the southern boundary BFR. result (a)...

Rising demand for medicinal plants has led to increased pressure on wild plant populations. This, combined with shrinking habitats, means that many species in South Africa are now facing local extinction. In 1997, a study was initiated determine the extent of trade African Lowveld (the low lying plains east Drakensberg escarpment), and investigate socio-economic factors influencing resource management. Trade not as extensive major urban markets such Durban or Witwatersrand (Johannesburg...

This paper analyses the edaphic and biological aspects of plant endemism in floristic lists from five edaphically matched sites, taxonomic regional Boras, Agulhas Plain, South Africa Barrens, south western Australia. The two regions are very closely terms their mediterranean-type climates, landforms, soil types disturbance regimes. Both have large neo-endemic floras. At Bora level, incidence local was almost identical on both continents (c. 6% 22%, respectively) endemics were not a random...
