Host specificity in South African mistletoes.
(2013)Mistletoes intimately connect to their host trees with a haustorium that allows them to access nutrients and water. Mistletoes in South Africa vary greatly in their degree of host specificity. Most species occur on a wide ... -
Impact of stocking rate, livestock type and livestock movement on sustainable utilisation of sourveld.
(2013-12-20)Data collected between 1992/93 and 1996/97 from two long-term grazing trials were used to investigate the interaction between grazing animals and veld grass. In the first trial, the impacts of stocking rate and time of ... -
Influence of drought or elephant on the dynamics of key woodland species in a semiarid African savanna.
(2000)Extensive drought - and elephant-related dieback of Colophospermum mopane and Acacia tortitis, respectively, offered an opportunity for increasing understanding of the causes of drought-related patch dieback, the factors ... -
The influence of environment and livestock grazing on the mountain vegetation of Lesotho.
(2013-12-09)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 influence of fertiliser nitrogen on soil nitrogen and on the herbage of a grazed kikuyu pasture in Natal.
(1994)The work reported in this thesis was designed to develop a better understanding of the fate of fertiliser nitrogen applied to a tropical pasture under field conditions, with the eventual objective of ... -
Management of kikuyu (Pennisetum clandestinum) for improved dairy production.
(2007)South African dairy farmers have generally used kikuyu pasture to tide them over from one ryegrass season to the next, and as a result of its resilient nature, have assumed careful management of it to be unnecessary. ... -
Managing Lolium perenne L. (perennial ryegrass) in a sub-tropical environment in KwaZulu-Natal, South Africa.
(1994)Lolium perenne L. (perennial ryegrass) generally fails to persist under the sub-tropical cpnditions of South Africa. Furthermore, little research data are available on how to manage this species locally. ... -
Monitoring serial changes in coastal grasslands invaded by Chromolaena odorata (L.) R.M. King and Robinson.
(2013-12-17)The objective of this study was to describe the impacts of the density of Chromolaena odorata (chromolaena) on species composition in coastal grasslands and to investigate serial changes in the vegetation following the ... -
Ngorongoro crater rangelands : condition, management and monitoring.
(2006)The Ngorongoro Crater is a volcanic caldera located within the Ngorongoro Conservation Area in Tanzania. The Crater comprises a flat grassland plain surrounded by steep, bushy walls. It contains extremely high densities ... -
The nitrogen economy of three irrigated temperate grass pastures with and without clover in Natal.
(2014-03-27)Abstract can be viewed in PDF document. -
Nutrient cycling in grazing systems.
(2004)This research was conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa. The research encompasses five different studies to assess nutrient cycling in intensive and extensive grazing systems with ... -
Optimal spatial and temporal utilization of grassland resources for extensive livestock production.
(2018)South Africa naturally experiences variation in rainfall patterns with distinct seasonal distribution. The anticipated disruptive effects of climate change, in this region, on vegetation dynamics is likely to accentuate ... -
Patch grazing at Kroomie.
(2003)The patch structure of the grass sward at Kroomie (26°25'38"E 33°48'30"S) in a semi-arid savanna in the Eastern Cape, South Africa, was investigated. The study was conducted on long term grazing trials on five treatments ... -
Patch grazing in the humid grasslands of KwaZulu-Natal.
(1995)Patch grazing may be an important factor providing the focus from which wide-scale veld degradation has occurred in the humid grasslands of KwaZulu-Natal. A number of discrete studies were therefore initiated to ... -
Potential of established pastures in the winter rainfall region.
(1986)The seasonal production of 11 pastures was evaluated in dryland and irrigated trials at eight sites in the Winter Rainfall Region. These data were related to ... -
Production and economics of Arado and Barka cattle in Eritrea.
(2007)Grazing lands in Eritrea are degraded due to decades of overstocking and consequent overgrazing. Since the rangelands are accessible to entire village communities, organisation and coordinated decision making regarding the ... -
Radical veld improvement in South Africa with special reference to the Highland sourveld of Natal.
(2015-04-28)No abstract available. -
Rangeland and animal performance trends in highland sourveld.
(2010)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 ... -
Rangeland degradation in the southern Kalahari.
(2013-12-17)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 ... -
Re-vegetation dynamics of land cleared of Acacia mearnsii (black wattle)
(2005)The overall aim of the study was to investigate re-vegetation of disturbed sites, using nursery grown plugs (from seedling trays) of Themeda triandra, Heteropogon contortus and Hyparrhenia dregeana in order to reach ...
