Above- and belowground competition in Savanna systems.
(2008)The structure and composition of savanna vegetation is influenced by resource availability and disturbance. Grasses, a major component of savannas, influence this resource availability by competing directly with trees ... -
Aspects of the ecology of grass seedlings used for revegetation of degraded land.
(2010)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 ... -
An assessment of the effect of season of grazing, stocking rate and rainfall on the dynamics of an arid rangeland on the west coast of South Africa.
(2005)A grazing trial investigating the effect of season of grazing and stocking rate initiated at the Nortier Experimental Farm in 1988 provided an opportunity to assess the response of the veld to both grazing and environmental ... -
Burning wetlands : the influence of fire on wetland vegetation structure and composition.
(2013)Water is a very important component of the natural world and human survival but water sources (river systems and wetlands) are becoming increasingly degraded and less functional. In particular the increase of woody C3 ... -
Cattle and veld interactions at the Armoedsvlakte Research Station.
(2011)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 ... -
The coastal grasslands of Maputaland, South Africa : effects of fire and grazing on vegetation structure, diversity, and composition.
(2007)A series of trials and investigations were implemented to address concerns surrounding the dynamics of the fire-climax wooded/edaphic grasslands within the iSimangaliso Wetland Park, northern KwaZulu-Natal, South Africa. ... -
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 ... -
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 ... -
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 ... -
Ecological effects of Festuca costata on the Drakensberg grasslands.
(2018)Fire and herbivory are important in determining the vegetation structure in savannas and grasslands. In addition, anthropogenic activities have significantly contributed to alterations in the relative abundance and ... -
The effect of application of nitrogen, phosphorus, potassium and sulphur fertilisers to a perennial ryegrass sward on yield, quality and apparent intake by dairy cows.
(2010)Perennial ryegrass is an intensive, temperate pasture grass that responds well to applied fertiliser. The purpose of this project was to study the effects of fertiliser on the productivity and quality of perennial ryegrass ... -
The effect of burning frequency on invertebrate and indigenous flowering forb diversity in a Drakensberg grassland ecosystem.
(2006)The KwaZulu-Natal Drakensberg, South Africa, is predominantly a grassland ecosystem maintained by fire. The effect of the current burning regime on invertebrate and flowering forb diversity in this ecosystem is poorly ... -
Effect of elevated temperatures on growth and defence of Vachellia 1 sieberiana seedlings grown with or without grass.
(2020)Warming is suggested to increase globally in the next few decades. Warming, soil nutrients, 2 water, CO2 and sunlight are the most important environmental factors for plant life. Elevated 3 temperatures can highly impact ... -
Effect of fire frequency on herbivore distribution and behaviour in the Kruger National Park, South Africa.
(2012)Fire plays an important role in structuring and maintaining savanna grassland ecosystems. Although regular fires are a characteristic feature of savannas, the effects of fire frequency on these systems are less well ... -
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 ... -
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 ... -
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 ... -
The effects of burning and mowing on microclimate and soil resources and implications for species change in the southern tall grassveld of KwaZulu-Natal.
(2004)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 ... -
Evaluation of improved Brachiaria grasses in low rainfall and aluminium toxicity prone areas of Rwanda.
(2010)Abstract available in the print copy. -
Forage systems for goat production in South Africa.
(2011)Goats are found in almost every country and are an important source of protein and produce lactose-free milk. In South Africa, survival rates of goat kids are low, mainly due to malnutrition. Intensive goat production ...
