Performance of invasive alien fountain grass (Pennisetum setaceum) along a climatic gradient through three South African biomes
(Elsevier B.V., 2014-03)
The knowledge of relative performance of plants across environmental gradients is critical for their effective management and for understanding future range expansion. Pennisetum setaceum is an invasive perennial grass ...
Plant invasions in arid areas: special problems and solutions: a South African perspective
(Springer Science+Business Media B.V., 2010)
Management of invasive alien plants in arid areas is complicated by the cryptic and stochastic nature of the invasion process, the low density of researchers, extension officers and farmers in these areas, the complex, ...
Post-dispersal fate of Acacia seeds in an African savanna
(SOUTHERN AFRICAN WILDLIFE MANAGEMENT ASSOC, 2005-10)
African Acacia species are often major contributors to the progressive increase in the woody component of savannas, a phenomenon commonly referred to as bush encroachment. In Hluhluwe-iMfolozi Park, the numbers of adult ...
Evidence for induced pseudo-vivipary in Pennisetum setaceum (Fountain grass) invading a dry river, arid Karoo, South Africa
We report the development of rootless plantlets in inflorescences of Pennisetum setaceum (Fountain grass) invasive in the Gamka River in the Karoo National Park, South Africa. The pseudo-vivipary appeared to have been ...
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, ...
Road verges as invasion corridors? A spatial hierarchical test in an arid ecosystem
Disturbed habitats are often swiftly colonized by alien plant species. Human inhabited areas may act as sources from which such aliens disperse, while road verges have been suggested as corridors facilitating their dispersal. ...
Distribution of the invasive alien tree Schinus molle in western South Africa
We examined the distribution of the invasive alien tree Schinus molle (Peruvian pepper tree; Anacardiaceae) in South Africa, where it was planted over large areas. Localities of planted and naturalized trees were mapped ...
Invasive potential of the Peruvian pepper tree (Schinus molle) in South Africa
We investigated the potential of an invasive alien tree to transform vegetation by quantifying the relative abilities of the alien tree Schinus molle and dominant native trees Acacia tortilis and Rhus lancea to compete for ...
Reproductive potential and seedling establishment of the invasive alien tree Schinus molle (Anacardiaceae) in South Africa
(Ecological Society of Australia, 2009)
Schinus molle (Peruvian pepper tree) was introduced to South Africa more than 150 years ago and was widely planted, mainly along roads. Only in the last two decades has the species become naturalized and invasive in some ...
