Proposals for the development of the Cape of Good Hope Nature Reserve : annexure to thesis

Binckes, Graeme 06 April 2020 (has links)
The Cape of Good Hope Nature Reserve occupies the southern end of the Cape Peninsula and thus of the Southern Peninsula Subregion referred to in the general study (photographs 2 and 29). The Reserve has an area of nearly 29 1/2 square miles; its coastline is some 24 miles in length. It is used both as a Nature Reserve and as a recreation area, the latter function being concentrated, in the main, within restricted coastal sites; apart from these, Cape Point is a considerable tourist attraction as is the drive through the Reserve. Existing access routes and travelling times to the Reserve are shown on Map No. 5.1, together with current proposals.

Key resource areas and management of buffalo (syncerus caffer caffer) on Molemane Eye Nature Reserve

Leitner, Peter Ewald 30 April 2013 (has links)
A research report submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfillment of the requirements for the degree of Master of Science (Environmental Sciences) Johannesburg, South Africa 7 February 2013 / In 2004 Molemane Eye Nature Reserve was stocked with 46 disease-free buffalo with the intention of generating sustainable revenues for the Reserve. However, the buffalo’s poor population growth rate and poor body condition during the dry seasons led to management reducing the buffalo population to 21 animals in 2010. The buffalo’s poor performance has drawn the attention to the potential nutritional limitations of the forage available during the dry season and to the importance of key resource areas. I examined the nutritional content of the buffalo forage using faecal analyses as proxy for nitrogen (N) and phosphorus (P), expecting a nutritional stress towards the latter part of the dry season. Data from the GPS/GSM collar on one of the buffalo cows was used to determine the dry season vegetation type selection and to identify key resource areas. A comparison of veld conditions was also done on the lowland vegetation types on Molemane Eye Nature Reserve and an adjacent property (Eye Area), which was earmarked for incorporation, to determine whether veld restoration work was required prior incorporation. It was established that the extended period of poor forage quality during the 2010 dry season was an important limiting factor for the buffalo as the forage quality dropped below the buffalo minimum nutritional requirements (Nf < 1.52 %, Pf < 2 %). A faecal sampling during early 2011 indicated that the nutritional stress period may last as long as 5 months (April to August). The buffalo did not select the vegetation types in proportional to their availability and narrowed their selection as the dry season progressed, preferring those containing woody elements. Of the 8 vegetation types indentified as key resource areas for buffalo during the dry season, the Eye Area holds 4 and contributes less than 5% to the key resource area already available on Molemane Eye Nature Reserve. The overall veld condition of the two areas was similar and no veld restoration work was deemed necessary. Although the incorporation of the Eye Area will shorten the distance between water and forage areas and have some nutritional benefits for buffalo in the dry season, mineral supplementation will be necessary for these valuable animals to become more productive and contribute to the economic objectives of Molemane Eye Nature Reserve.

The use of South Africa's nature areas in the promotion of tourism and economic development

Pithers, Linda January 2001 (has links)
Magister Philosophiae - MPhil / South Africa has developed an extensive network of parks, nature reserves and conservation areas, the stated purpose of which is to both promote and protect nature and, particularly in the case of state-owned resources, to harness the power of tourism in social and economic development. This study examines the impact on rural and urban communities of proclaimed 'nature areas' and related efforts by the state to grow the economic and developmental contribution of tourism in the regions concerned. Through interrogating this 'triangulation' of nature, tourism and local economic development the pattern of benefit distribution from the protection of nature areas is highlighted.

Species density of the Southern lesser bushbaby (Galago moholi) at Loskop Dam Nature Reserve, Mpumalanga, South Africa, with notes on habitat preference

Ray, Ian S. 03 May 2014 (has links)
A population survey was conducted on Galago moholi along the road system at Loskop Dam Nature Reserve, Mpumalanga province, South Africa. The data were analyzed using the maximum perpendicular distance, mean perpendicular distance, and maximum reliable perpendicular distance methods. Vegetation sample plots were constructed at the location of each individual sighted in order to analyze the species’ habitat use. The results indicate that the species density of G. moholi is significantly lower at Loskop Dam Nature Reserve than previously reported at other sites within South Africa. G. moholi was found to prefer areas with high concentrations of Dichrostachys sp., Combretum sp., or Acacia sp. One individual was observed consuming vegetative matter, which may indicate that the population within the reserve is utilizing available resources in a different way than populations in other parts of southern Africa. / Department of Anthropology

Environmental management strategy : Krantzkloof Nature Reserve, a case study.

Seaman, Paul. 31 January 2011 (has links)
KZN Nature Conservation Services budgetary cuts for the KrantzkloofNature Reserve (KNR) has led to economic shortfalls in important areas like facilities maintenance and invader plant control. The study has found that the benefits of maintaining KNR, determined from the estimated Total Economic Value (TEV), are huge and far outweigh the budget shortfall. The shortfall has been closed by user charging, the timing of which has prevented any deterioration in the facilities and ecology ofKNR due to budget cuts. Facilities maintenance needs to be prioritized to protect the user charge funding base and alien invader control needs to be prioritized due to escalating costs and the magnitude of the problem. The study has found that subcatchment stakeholder groups in the developing Emolweni forum, within which KNR is strategically placed, are strongly associated with local conservancies which will essentially provide the backbone for the envisaged forum. In order for stakeholder groups to be more representative, however, it is important for local conservancies to fmd a way to draw in community groups not normally involved in conservation work. The forum should provide networking and support for projects like environmental education, income generation and rehabilitation that will allow these community groups to participate in conservation work in a meaningful way. Delivery should occur through strategically placed community institutions like schools and clinics and should target young people and the unemployed. Nature reserves have largely untapped resources and a quasi- option value project is explored that combines alien vegetation control with the development of an indigenous nursery in an ecological and economic sustainable manner. It is envisaged that income derived from the sale of horticultural plants may substitute the income derived from medicinal plants and thus reduce the pressure applied on KNR's threatened resources by the unemployed. The study recommends that the subcatchment be divided into manageable units, based on a situational analysis, out of which particular criteria and objectives can be developed. Surveys, inventories, mapping and research activities should be carried out, with reports on the state or use of soil, water and biota submitted to the forum, which can then provide management solutions. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, Durban, 2006.
