Signed: Brittany C. Schultz Date: March, 2020. Copyright © 2020 Stellenbosch University All rights reserved 2 Stellenbosch University https://scholar.sun.ac.za Abstract The collapse of prey-bases threatens many predators globally and may contribute to some predators’ localised extinctions. A similar cascade is a potential threat to leopard Panthera pardus and their medium-sized mammalian prey populations in the Fynbos biome. Medium-sized mammals have reportedly been negatively impacted by a number of anthropogenic threats in agricultural land-covers that act as buffers between human development and natural fynbos habitats. One of these threats and a driver of many, is the loss of habitat from human-caused land-cover changes. The Boland Mountain Complex (BMC) is one of the eight patches of protected mountainous areas, proclaimed as a United Nations Environmental, Educational, Scientific and Cultural Organization’s (UNESCO) World Heritage Site, in the Western Cape Province, South Africa.

  • Input Towards the Development of an Integrated Implementation Strategy
    TM 1683 Source-to-Sea River Corridor Restoration for People & Nature TOWARDS THE DEVELOPMENT OF AN INTEGRATED IMPLEMENTATION STRATEGY Interim Summary Report – November 2012 1 PROJECT SUMMARY This project, made possible through funding provided by TMF, aims to facilitate a consultative process to provide stakeholder input towards the development of an Integrated Implementation Strategy for the Source- to-Sea concept, developed for the Sand River Catchment within the City of Cape Town. As one of the most important catchments within the City of Cape Town from a biodiversity perspective, a significant amount of riverine improvement, rehabilitation and maintenance work is being undertaken by the local authority, parastatals and civil society. This project aimed to align these individual efforts towards a common vision based on the protection and enhancement of biodiversity within the catchment. It provides some guidelines as to how, where and what type of work should be undertaken. It is hoped that the through the project, communication between role-players in the catchment will be improved enabling streamlining of future on-the-ground implementation. The objectives of this project included: Phase 1: 1. Prioritising rehabilitation and conservation work in the Sand River catchment; 2. Defining a specific vision & target for each identified & prioritised management area; Phase 2: 3. Identifying what resources & actions are necessary to achieve these targets in each management area. This will take the form of collaborating with stakeholders to determine the contributions each can make towards the achievement of these targets; 4. Identifying what additional resources are required to inform future applications for funding to achieve these set targets.

    Custodians of the Cape Peninsula: A historical and contemporary ethnography of urban conservation in Cape Town by Janie Swanepoel Thesis presented in fulfilment of the requirements for the degree of Master of Social Anthropology in the Faculty of Arts and Social Sciences at Stellenbosch University Supervisor: Prof Steven L. Robins December 2013 Stellenbosch University http://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. December 2013 Copyright © 2013 Stellenbosch University All rights reserved II Stellenbosch University http://scholar.sun.ac.za ABSTRACT The official custodian of the Cape Peninsula mountain chain, located at the centre of Cape Town, is the Table Mountain National Park (TMNP). This park is South Africa’s only urban open-access park and has been declared a World Heritage Site. This thesis is an anthropological and historical examination of the past and present conservation of the Cape Peninsula . I provide an overview of the relationship between the urban environment and the Cape Peninsula aiming to illustrate the produced character of the mountains and its mediation in power relations. This study of custodianship reveals that protecting and conserving the Cape Peninsula is shaped by the politics of the urban and natural environment as well as by the experience of living in the city.

Our Vision Biodiversity • Community • Heritage • Safety Our goal is to conserve our natural plant and animal life at Tokai Park while promoting the park as a recreational gateway to our greatest natural asset and internationally-renowned World Heritage Site, Table Mountain National Park. Opening notes: 2021 and the UN Decade on Ecological Restoration “One of the biggest threats to conservation in the world, South Africa and in this case in Cape Town is public opinion. Biodiversity and the environment are often at odds with human interests. Whether it is resources such as rain forests, oil, habitable land, water resources, minerals, it is humans that prevail at the expense of the environment. In Cape Town there is an ever-increasing human population and pressure on land for housing primarily on the lowlands where CFSF is limited to its last 11%. One of the three most significant and richest remaining conservation parcels is Kenilworth which is privately owned and subject to increasing pressure to be developed. Standard legal environmental processes are being overridden by politicians in conflict with the Global Strategy for Plant Conservation to which South Africa is a signatory. Tokai is the other area where CFSF can survive but a significant pressure group is lobbying for the area to remain under pine plantation to satisfy their understanding of conservation and personal needs. These two areas may be the last chance in Cape Town to make significant contributions to saving the remnants of CFSF.

  • Table Mountain National Park Position Statement: Tokai and Cecilia Plantations
    Table Mountain National Park Position Statement: Tokai and Cecilia Plantations Date: 2016-08-30 The devastating March 2015 fires which burnt Upper Tokai plantation have refocused the public's attention on the future of the area. Over the past few months a range of letters, opinions, SMSs, advertisements and campaigns have been published and aired in the media and other platforms on the safety issue and status of remaining plantations in the Lower Tokai area of the Table Mountain National Park (TMNP). The facts pertaining to the harvesting of plantation trees are: 1. Tokai and Cecilia are not natural forests but commercial plantations established in the early 1900s by government to provide timber for industry. Fynbos was eradicated in these areas to make way for these plantations. 2. The decision to phase out commercial plantations on the Peninsula was not made by SANParks but by central government in 1999. As the then Minister of Agriculture, Forestry and Fisheries, stated in Parliament at the time “…a thorough, Cabinet endorsed process was followed that led to the decision to end commercial forestry at these locations, and assign the land to SANParks.” 3. The Minister also stated that it is not possible to revisit the decision to end commercial forestry as “…legal commitments are in place...” and “…neither is it considered desirable to do so.” 4. The plantations are not being removed because they are alien to the Cape; they are being harvested as a planted crop grown on a commercial basis. Furthermore, the plantations are not being harvested by SANParks but by a private company, MTO Forestry, which was awarded the public tender by then Department of Water Affairs and Forestry (DWAF) in 2004.
