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 ...
Are private and social goals aligned in pasture-based dairy production?
(Elsevier Ltd., 2018)
To become more sustainable, dairy farms should aim to maximise productivity at a minimum cost to the environment. Standard environmental impact measures were combined with non-parametric total factor productivity analysis ...
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 ...
No Evidence-Based Restoration Without a Sound Evidence Base: A Reply to Guldemond et al.
(Society for Ecological Restoration International, 2012-03)
Evidence-based practice is not possible without an evidence base. Guldemond et al. confuse our attempt at assessing the status of the evidence base of restoration programs in South Africa with attempting to assess whether ...
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 ...
Pioneers and Perches—Promising Restoration Methods for Degraded Renosterveld Habitats?
(Society for Ecological Restoration International, 2012-01)
Areas of abandoned agricultural fields are globally increasing and are also common features in the Cape Lowlands of South Africa. Previous restoration attempts in degraded West Coast renosterveld, a mediterranean-climate ...
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 ...
