Determinants of community composition and diversity in KwaZulu-Natal mesic grasslands : evidence from long-term field experiments and pot and plot competition experiments.
A predictive understanding of plant community response to various environmental influences (e.g. type, timing and frequency of disturbance, site productivity, fertilization, etc.) is a general goal of plant ecology. This ...
Rangeland and animal performance trends in highland sourveld.
Long-term trends in rangeland sward dynamics (species composition, structure, productivity) were examined on three trials established between 1989 and 1996 at Kokstad Research Station in the Highland Sourveld, while ...
The influence of environment and livestock grazing on the mountain vegetation of Lesotho.
The mountains of Lesotho form the catchments for the Lesotho Highlands Water Project (LHWP), which is presently under construction, and their condition will determine the longevity of the LHWP. The mountain rangelands ...
The nitrogen economy of three irrigated temperate grass pastures with and without clover in Natal.
Abstract can be viewed in PDF document.
The effects of burning and mowing on microclimate and soil resources and implications for species change in the southern tall grassveld of KwaZulu-Natal.
Promotion of a predictive understanding of plant community response to various forms, frequencies and seasons of disturbance, either through the direct physical effect on biota and or indirect effect on plants, through ...
Cattle and veld interactions at the Armoedsvlakte Research Station.
A long-term grazing trial was started in 1977 at Armoedsvlakte Research Station, about 10km west of Vryburg, in Tarchonanthus veld of the Ghaap’s Plateau, which is a variation of the Kalahari Thornveld veld type. The ...
Recovery, resilience and stability of piospere systems in the Kruger National Park.
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 ...
Aspects of the ecology of grass seedlings used for revegetation of degraded land.
As restoration ecology has matured as a science there has been increased interest in the relationship between species diversity and landscape health. Degraded landscapes tend to be resource poor, which limits species ...
Seed production studies with weeping lovegrass Eragrostis curvula (Schrad.) Nees.

Factors affecting savanna tree sapling recruitment.
Savannas are globally important ecosystems characterized by the coexistence of trees and grasses. Woody plants, which are slow-growing dominant life forms, influence the physiognomic structure and function of savanna ...
