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 ...
The effectiveness of active and passive restoration on recovery of indigenous vegetation in riparian zones in the Western Cape, South Africa: A preliminary assessment
Riparian ecosystems in South Africa's fynbos biome are heavily invaded by alien woody plants. Although largescale clearing of these species is underway, the assumption that native vegetation will self-repair after ...
ABSTRACT: Fragmentation effects and extinction debt in South African fynbos
(Elsevier B.V., 2017)
Wood anatomical traits as a measure of plant responses to water availability: invasive Acacia mearnsii De Wild. compared with native tree species in fynbos riparian ecotones, South Africa
Riparian ecotones in the fynbos biome of South Africa are heavily invaded by woody invasive alien species,which are known to reduce water supply to downstream environments. To explore whether variation in species-specific ...
Potential seed dispersal distances of native and non-native fleshy fruiting shrubs in the South African Mediterranean Climate Region
Bird flight distances for the small Zosterops capensis, the medium-size Pycnonotus capensis and the large Colius striatus were extracted from these birds’ initial ring and subsequent recapture locations and expressed on ...
Hydrological responses of a valley-bottom wetland to land-use/land-cover change in a South African catchment: making a case for wetland restoration
(Society for Ecological Restoration, 2015)
Valley-bottom wetlands are valuable assets as they provide many ecosystem services to mankind. Despite their value, valley-bottom wetlands are often exploited and land-use/land-cover (LULC) change results in trade-offs in ...
System dynamic modeling to assess economic viability and risk trade-offs for ecological restoration in South Africa.
Can markets assist by providing support for ecological restoration, and if so, under what conditions? The first step in addressing this question is to develop a consistent methodology for economic evaluation of ecological ...
Identifying challenges to building an evidence base for restoration practice
(MPDI AG, Basel, Switzerland, 2015)
Global acknowledgement of ecological restoration, as an important tool to complement conservation efforts, requires an effort to increase the effectiveness of restoration interventions. Evidence-based practice is purported ...
The effect of land cover and ecosystem mapping on ecosystem risk assessment in the Little Karoo, South Africa
Extinction-risk assessments aim to identify biological diversity features threatened with extinction. Although largely developed at the species level, these assessments have recently been applied at the ecosystem level. ...
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 ...
