Studies of the management of grazing resources on the Makatini Flats and Pongolo River Floodplain.
(1988)Subsequent to the impounding of the Pongolo river in the 1970's, development of irrigated agriculture on the Makatini flats has been reducing the area of vegetation available for grazing, and flooding patterns on the ... -
The responses of grasses to fire and bush clearing in the Hluhluwe Game Reserve.
(1992)Contemporary and historical studies of the flora of the Hluhluwe Game Reserve (HGR), have emphasised the woody component whilst little work has been performed on the herbaceous vegetation. This is particularly true with ... -
A comparative classification of the sourish-mixed bushveld on the farm Roodeplaat (293 JR) using quadrat and point methods.
(1995)An area and a point-based technique were used together at each of the same 75 sampling sites (stands), on a Sourish-Mixed Bushveld farm, to collect data for the classification and mapping of the vegetation. Both sets of ... -
Grasslands of Umtamvuna Nature Reserve, KwaZulu-Natal : a description and recommendations for monitoring.
(1995)The main aim of this study was to classify and map the threatened coastal grassland communities of the 3 257 ha Umtamvuna Nature Reserve (UNR) in KwaZulu-Natal (30°07'30" to 300 11'05"E; 30°55'00" to 31°04'30"S). Secondary ... -
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 ... -
Vegetation change over fifty years in humid grasslands of KwaZulu-Natal (Acocks's sites)
(1997)Eighty three of Acocks's sites, originally surveyed about 50 years ago, were resurveyed in 1996 to determine the extent of grassland change in the humid grasslands of KwaZulu-Natal. Sites were relocated using 1:10 000 ... -
A comparison of in-field techniques for estimating the feed intake of young boer goats on a Leucaena leucocephala/grass hay diet.
(1997)Two methods of estimating the intake of a 25% leucaena : 75% grass hay diet by young male Boer goats were assessed, (a) The purine derivative technique which uses the urinary excretion of purine derivatives (expressed ... -
Vegetation succession and soil properties following the removal of pine plantations on the eastern shores of Lake St Lucia, South Africa.
(1998)Pine plantations have been established on secondary grassland on the dune systems of the Eastern Shores of Lake St Lucia, KwaZulu-Natal, South Africa for the past 40 years. These plantations have been progressively felled ... -
Effect of stocking rate and rainfall on rangeland dynamics and cattle performance in a semi-arid savanna, KwaZulu-Natal.
(1998)Considerable understanding of the functioning of semi-arid systems is still needed to enable range managers to formulate management policies, with a degree of confidence. Long term data sets that encompass a wide range ... -
Effect of perennial water on soil, vegetation and wild herbivore distribution in southeastern Zimbabwe.
(1999)The effects of artificially supplied perennial water on soil properties, vegetation dynamics and the distribution of large herbivores was investigated in southeastern Zimbabwe. Data collection took place between March ... -
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 ... -
Soil, herbaceous and woody responses to different methods of bush control in a mesic eastern Cape savanna.
(2000)Bush encroachment is a major problem for the savannas supporting livestock in the Eastern Cape. Farmers employ chemical poisoning and mechanical clearing of woody vegetation to improve grass production. This thesis ... -
Monitoring serial changes in coastal grasslands invaded by Chromolaena odorata (L.) R.M. King and Robinson.
(2000)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 ... -
Resource overlap within a guild of browsing ungulates in a South African savanna.
(2000)Food selection by free-ranging black rhinoceros, eland, giraffe and kudu as well as the utilisation of vegetation types by the latter three browsers were investigated over an entire seasonal cycle, from June 1998 to July ... -
Effect of season and type of fire on Colophospermum mopane woodland in the south-eastern lowveld of Zimbabwe.
(2000)The majority of the vegetation types occurring on Malilangwe Estate, in the south-eastern lowveld of Zimbabwe, are dominated by Colophospermum mopane (mopane). Over the past 30-50 years the stand density of these mopane ... -
Seed and seedling dynamics of certain acacia species as affected by herbivory, grass competition, fire, and grazing system.
(2001)The influence of herbivory, grass competition and grazing system on emergence, growth and survival of Acacia seedlings in burnt and unburnt areas was investigated in their first growing season, from September 1997 to May ... -
Determinants of grass production and composition in the Kruger National Park.
(2003)The dynamics and complexities of climate-soil-vegetation relations in the Kruger National Park are poorly known. Although primary production and composition of the grass layer are very important components of the Park's ... -
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 ... -
A strategy for optimal beef production off sourveld.
(2003)The economic necessity of a better production strategy on sourveld promoted this study. Production of marketable two-tooth steers in the summer season and overwintering of all cattle without excessive feed costs were ... -
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 ...
