Effects of alien plant management and fire on soil seed banks and regeneration in the Cape Peninsula National Park, South Africa
(2004)The regeneration of alien and indigenous vegetation in various post-fire environments, following the extensive January 2000 wildfires on the Cape Peninsula, South Africa, is described. The effects of dry season wildfire burning ... -
Effects of alien plant management, fire and soil chemistry on selected soil microbial populations in the Table Mountain National Park, South Africa
(NATL INQUIRY SERVICES CENTRE PTY LTD, 2005-06)This pilot study examined changes in soil chemistry and microbial population sizes following the extensive wildfires in 2000 on the Cape Peninsula. The effects of standing alien plants and stacks of mechanically-cleared ... -
A decision-making framework for restoring riparian zones degraded by invasive alien plants in South Africa
(2005-11)Riparian habitats in many parts of South Africa are severely degraded by invasive alien plants, especially trees. These invasions reduce water yields from catchments and affect riverine functioning and biodiversity. ... -
SAWISE and HERS-SA: Raising the profile of women in science
(ACAD SCIENCE SOUTH AFRICA A S S AF, 2006-08) -
Banking on seeds: can our riverine plant communities fight back after heavy invasion
(Botantical Society, 2006-12) -
A case study of landholder attitudes and behaviour towards the conservation of Renosterveld, a critically endangered vegetation type in the Cape Floral Kingdom, South Africa
(Springer, 2007)Attitudes and behaviour of private landholders towards the conservation of a highly transformed and critically endangered habitat, Overberg Coastal Renosterveld (OCR) (a grassy-shrubland of the Cape Floral Region, SA) are ... -
Effect of alien plant invasion on riparian seed bank assembly rules
(2007)Globally, riparian areas are particularly susceptible to invasion. Once invaded, riparian systems play a major role in the spread of invasive species throughout the landscape; particularly those species with high seed loads ... -
Riparian vegetation: degradation, alien plant invasions, and restoration prospects
(Blackwell Publishing Ltd, 2007)Rivers are conduits for materials and energy; this, the frequent and intense disturbances that these systems experience, and their narrow, linear nature, create problems for conservation of biodiversity and ecosystem ... -
Towards best practice in management of road reserves
(Botanical Society, 2007-03) -
Genetic and morphological comparisons of a potentially invasive weed (Argemone ochroleuca) from its natural (Mexico) and invaded (South Africa) habitat
(Elsevier, 2007-04)Morphological and genetic comparisons of a potentially invasive weed (Argemone ochroleuca) from its natural (Mexico) and invaded (South Africa) habitats are presented. Seeds from 14 Mexican and 13 South African populations ... -
Re-evaluation of a riparian restoration experiment in the Western Cape Province: Status 8 years down the line
(Elsevier, 2007-04)In 1998, a study was initiated to assess the relative effectiveness of three different sowing treatments for reducing soil erosion and restoring indigenous riparian vegetation cover after alien clearing in the Western Cape. ... -
Managing roads, rivers and powerline servitudes as biodiversity corridors through the landscape
(Elsevier, 2007-04)National and Provincial road verges are managed to promote road safety and conserve biodiversity. In most cases the management is carried out by contractors and funded by the Extended Public Works Programme. In some cases, ... -
The Movers and the shakers: invasive alien plant dispersal interactions with disturbances
(Elsevier, 2007-04)We consider how a range of vectors (“movers”) that disperse seeds in creeps and jumps at different spatial and temporal scales, and disturbances (“shakers” - natural and man-made disruptions of established natural ... -
Guidelines for improved management of riparian zones invaded by alien plants in South Africa
(Elsevier B.V., 2008)This paper reviews the results of recent research on riparian vegetation recovery following the clearance of invasive alien plants. In Fynbos, Grassland and Savanna Biomes, riparian ecosystems were found to have relatively-high ... -
The effectiveness of active restoration following alien clearance in fynbos riparian zones and resilience of treatments to fire
(Elsevier B.V., 2008)In 1998, a restoration field trial was initiated in a catchment near Wellington (Western Cape, South Africa) to determine whether fynbos riparian scrub vegetation cleared of woody invasive alien trees require post-clearance ... -
Diversity and species turnover on an altitudinal gradient in Western Cape, South Africa: baseline data for monitoring range shifts in response to climate change
(SANBI, 2008)A temperature and moisture gradient on the equator-facing slope of Jonaskop on the Riviersonderend Mountain, Western Cape has been selected as an important gradient for monitoring the effects of climate change on fynbos ... -
Reproductive biology and ecology of selected rare and endangered Oxalis L. (Oxalidaceae) plant species
(Elsevier Ltd., 2008)About twenty-five percent of all southern African Oxalis species are rare/endangered and highly localized, making them especially vulnerable to extinction through inbreeding, low genetic variation, disrupted biological ... -
Can riparian seed banks initiate restoration after alien plant invasion? Evidence from the Western Cape, South Africa
(Elsevier B.V, 2008)Riparian zones are complex disturbance-mediated systems that are highly susceptible to invasion by alien plants. They are prioritized in most alien-plant management initiatives in South Africa. The current practice for the ... -
Drought induced xylem embolism in four riparian trees from the Western Cape Province: Insights and implications for planning and evaluation of restoration
(Elsevier B.V., 2008)In Mediterranean climates, rainfall is restricted to periods of low evaporative demand, leaving plants to survive the summer drought. The purpose of this study was to determine the contribution of drought tolerance to the ... -
Phenotypic plasticity among Echium plantagineum populations in different habitats of Western Cape, South Africa
(Elsevier B.V., 2008)This paper addresses phenotypic variation among Paterson's Curse (Echium plantagineum L.) populations in four different habitat types (tar road verges, dirt road verges, abandoned fields and natural areas) in the Western ...
