Are Socioeconomic Benefits of Restoration Adequately Quantified? A Meta-analysis of Recent Papers (2000–2008) in Restoration Ecology and 12 Other Scientific Journals. Restoration Ecology
(Society for Ecological Restoration International, 2010)Many ecosystems have been transformed, or degraded by human use, and restoration offers an opportunity to recover services and benefits, not to mention intrinsic values. We assessed whether restoration scientists and ... -
Distribution of the invasive alien tree Schinus molle in western South Africa
(2009-05-20)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 ... -
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. ... -
Evidence for induced pseudo-vivipary in Pennisetum setaceum (Fountain grass) invading a dry river, arid Karoo, South Africa
(Elsevier, 2008)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 ... -
Invasive alien plants infiltrate bird-mediated shrub nucleation processes in arid savanna
(Blackwell, 2007)1 The cultivation and dissemination of alien ornamental plants increases their potential to invade. More specifically, species with bird-dispersed seeds can potentially infiltrate natural nucleation processes in ... -
Invasive potential of the Peruvian pepper tree (Schinus molle) in South Africa
(2009-05-21)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 ... -
Linking ecosystem services and water resources: landscape-scale hydrology of the Little Karoo
(The Ecological Society of America, 2007)There is growing acknowledgement of the dependence of human society on ecosystem services and of the fact that service delivery is being compromised by human impacts on ecosystems. This paper describes the linkage between ... -
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, ... -
Megastigmus wasp damage to seeds of Schinus molle
(2009-05-29)Understanding the reasons why some alien species become invasive may help to identify appropriate management strategies. One hypothesis often cited to explain invasion success is the enemy release hypothesis (Williams 1954; ... -
Megastigmus wasp damage to seeds of Schinus molle, Peruvian pepper tree, across a rainfall gradient in South Africa: implications for invasiveness
(The Entomological Society of Southern Africa, 2008) -
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 ... -
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 ... -
Road verges as invasion corridors? A spatial hierarchical test in an arid ecosystem
(Springer, 2008-02-14)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. ... -
Soil type, microsite, and herbivory influence growth and survival of Schinus molle (Peruvian pepper tree) invading semi-arid African savanna
(Springer Science+Business Media B.V., 2009)Naturalization of Schinus molle (Anacardiaceae) has been observed in semi arid savanna of the Northern Cape Province of South Africa. However, with high dispersal ability, the species is expected to achieve greater densities ... -
Soil type, microsite, and herbivory influence S.molle growth
(2009-05-29)The study involved a field manipulation experiment over 14 months using a factorial block design to examine transplanted seedlings in different savanna environments. The experiments examine the effects of soil type (sandy ... -
Superiority in competition for light: A crucial attribute defining the impact of the invasive alien tree Schinus molle (Anacardiaceae) in South African savanna
(Elsevier Ltd., 2008)Invasion of ecosystems by woody alien plant species is a widespread phenomenon. Interspecific competition has often been suggested as a mechanism for replacement of one species by another, but this is rarely tested. We ... -
