Bacillus anthracis is the causal agent of anthrax which primarily affects ungulates, occasionally carnivores and less frequently humans. The endospores of this soil-borne bacterium are highly resistant to extreme conditions, and under ideal conditions, anthrax spores can survive for many years in the soil. The bacterium is generally found in soil at sites where infected animals have died. When these spores are exposed, they have the potential to be ingested by a mammalian species which could lead to an anthrax outbreak. Anthrax is almost never transmitted directly from host to host, but is rather ingested by herbivores while drinking, grazing or browsing in a contaminated environment, with the exception of scavengers and carnivores consuming infected prey. Anthrax is known to be endemic in the northern part of Kruger National Park (KNP) in South Africa (SA), with occasional epidemics spreading southward into the non-endemic areas. The aim of this study is to identify and map areas that are ecologically suitable for the harbouring of B. anthracis spores within the KNP. Anthrax surveillance data and selected environmental variables were used as inputs to the maximum entropy (Maxent) species distribution modelling method. Five-hundred and ninety-seven anthrax occurrence records, dating from the year 1988 to 2011, were extracted from the Skukuza State Veterinary Office’s database. A total of 40 environmental variables were used and their relative contribution to predicting suitability for anthrax occurrence was evaluated using Maxent software (version 3.3.3k). Variables showing the highest gain were then used for subsequent, refined model iterations until the final model parameters were established. The environmental variables that contributed the most to the occurrence of anthrax were soil type, normalized difference vegetation index (NDVI), land type and precipitation. A map was created using a geographic information system (GIS) that illustrates the sites where anthrax spores are most likely to occur throughout the Park. This included the known endemic Pafuri region as well as the low lying soils along the Shingwedzi-Phugwane-Bubube rivers and the Letaba-Olifants river drainage area. The outputs of this study could guide future targeted surveillance efforts to focus on areas predicted to be highly suitable for anthrax, especially since the KNP uses passive surveillance to detect anthrax outbreaks. Knowing where to look can improve sampling efficiency and lead to increased understanding of the ecology of anthrax within the KNP. / Dissertation (MMedVet)--University of Pretoria, 2013. / Production Animal Studies / unrestricted

During the recession period of 2008/2009, global tourism declined by 8%. This was also evident is South Africa with the domestic travel market shrinking by 8% as well. However, this did not apply to the Kruger National Park (KNP) which experienced a sustained Accommodation Unit Occupancy growth of 1.6% during the same period. Visitors to the KNP thus see it as an attractive holiday destination irrespective of tough economic conditions characterised by less disposable income. To sustain this growth, it is important to be aware of the reasons visitors still visit the KNP during a recession. The aim of this study was to determine the reasons why visitors still travelled to the KNP during the 2008/2009 recession. This can be done by analysing the visitors’ behaviour and the motivational factors (internal feelings of the visitors) and determinants of the demand (income and exchange rates for instance) that influenced visitors’ choice to visit the KNP. To achieve this aim, a survey was conducted at the KNP between 15 and 20 December 2009 (high season). A total of 355 questionnaires were completed, after which a number of analyses were done to determine the effects of the recession on travel behaviour. For the purpose of this study, two articles were written. Article 1 is titled: “Motivations of visitors to the Kruger National Park during the 2008/2009 recession period”. The aim of this article was to determine the motivations of visitors to the KNP during the recession. A factor analysis on the motivations to visit the park was conducted, of which the following factors obtained the highest mean values: Escape, Wildlife experience and Family benefits. Push factors to the KNP were important to such an extent that visitors regarded visiting the park as a primary need or lifestyle. The results furthermore showed that visitors might have adapted their spending behaviour at the park to still afford to visit the park during the recession. This article provides a better understanding of visitors’ feelings towards the KNP, especially amidst recessions which, in turn, will improve niche marketing and a competitive advantage. Article 2 is titled: “Factors that influenced demand to the Kruger National Park during the 2008/2009 economic recession”. The aim of this article was to identify the determinants that influence the demand for visits to the KNP. Due to the homogeneous nature of the park’s market, the results of the stepwise logistic regression analysis revealed a few socio-demographic and behavioural determinants that influenced visitors’ demand to the park. The motives Escape and Souvenirs were the only two behavioural determinants while the provinces Gauteng and Mpumalanga were the only socio-demographic determinants. These two provinces are the two main markets for the KNP. Visitors indicated that visiting the KNP is a great way of escaping their busy metropolitan areas, especially in the Gauteng province. Mpumalanga residents have many tourism attractions in their province thus lowering the chances that they will visit the KNP. The determinant Souvenirs indicates that visitors adapted their spending at the park to still be able to afford visits. It was also found that demand to visit the park was not greatly influenced by the recession, because visitors could adapt their spending at the park. This is the first time the determinants of demand to a national park during a recession period have been conducted. The study indicated that visiting natural areas may have become a primary need or part of a lifestyle, especially during the 2008/2009 recession period. This article gives park management guidelines that will ensure the sustainability of the KNP because this information now allows for well-planned, thorough marketing and management of the park. In the case of KNP, which has a homogeneous market, the number of determinants identified influencing demand for visiting the park is fewer than has been found in other studies done on heterogeneous markets. This study therefore also makes a valuable methodological contribution in relation to analysing demand of homogeneous and heterogeneous markets. / Thesis (M.Com.
