Genetic and morphological comparisons of a potentially invasive weed (Argemone ochroleuca) from its natural (Mexico) and invaded (South Africa) habitat
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
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. ...
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
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
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 ...
Towards best practice in management of road reserves
(Botanical Society, 2007-03)
Managing roads, rivers and powerline servitudes as biodiversity corridors through the landscape
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
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 ...
SAWISE and HERS-SA: Raising the profile of women in science

Effects of invasion of fire-free arid shrublands by a fire-promoting invasive alien grass (Pennisetum setaceum) in South Africa
(Ecological Society of Australia, 2009)
Arid shrublands in the Karoo (South Africa) seldom accumulate sufficient combustible fuel to support fire. However, as a result of invasion by an alien perennial grass (Pennisetum setaceum), they could become flammable. ...
