Rangeland degradation in the southern Kalahari.
(2000)Observations by local people in the Mier area, southern Kalahari, South Africa, indicated that degraded rangeland does not recover within a time frame acceptable to landowners. Pristine vegetation in this linear dune ... -
Recovery, resilience and stability of piospere systems in the Kruger National Park.
(2010)Water provision is an important tool in the management of savanna ecosystems. Artificial water sources are a potential focus for degradation (biodiversity and loss of ecosystem resilience at a range of spatio-temporal ... -
The roles of competition, disturbance and nutrients on species composition, light interception and biomass production in a South African semi-arid savanna.
(2012)Plants are the major source of food or energy required to sustain life on the planet, but humans are grappling with the deteriorating conditions of natural ecosystems such as compositional change, desertification, invasive ... -

Short-term effects of mixed grazing by cattle and sheep in highland sourveld.
(1994)Data derived from a long-term grazing trial were used to determine short-term effects of mixed grazing by cattle and sheep in Highland Sourveld. Five cattle to sheep ratio treatments (viz. 1 :0, 3:1, 1 :1, 1 :3, 0:1) ... -
Soil loss and run-off in Umfolozi Game Reserve and the implications for game reserve management.
(1988)Two management blocks were set aside in Umfolozi Game Reserve (UGR) to compare different management approaches. In one, the non-cull block, a noninterventionist policy was followed and no large mammals ... -
A system for supporting wetland management decisions.
(1999)In South Africa, the loss of wetlands and their associated benefits has been considerable. A need was identified for a system that, using available information, would assist in achieving a balance between local, mainly ... -
Towards a predictive understanding of savanna vegetation dynamics in the eastern Lowveld of South Africa : with implications for effective management.
(2005)The purpose of this study was to develop and test a predictive understanding of the vegetation dynamics of the Lowveld of South Africa (30°35'E to 30°40'E and 24°00'S to 25°00'S). The study covered about 5000 km2 in ... -
Towards formalized adaptive management in succulent valley bushveld.
(1993)This study was designed to provide the means for implementing formal scientific vegetation management 1n the succulent valley bushveld of the eastern Cape, South Africa. Nowhere in the world has a detailed, ...
