The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage. -

Exploring the Invasion of the Guttural Toad Sclerophrys Gutturalis in Cape Town Through a Multidisciplinary Approach
Exploring the invasion of the guttural toad Sclerophrys gutturalis in Cape Town through a multidisciplinary approach Giovanni Vimercati Dissertation presented for the degree of Doctor of Philosophy in the Faculty of Science at Stellenbosch University Supervisor: Dr G. John Measey Co-supervisor: Dr Sarah J. Davies March 2017 Stellenbosch University https://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 authorship owner thereof (unless to the extent explicitly otherwise stated) and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Giovanni Vimercati Date: March 2017 Copyright © 2017 Stellenbosch University All rights reserved Stellenbosch University https://scholar.sun.ac.za Abstract Invasive populations of amphibians may have considerable ecological and socio-economic impacts; reconstructing their invasion dynamics is essential to perform adaptive management. Investigating these populations is also an opportunity to address eco- evolutionary questions; it helps to improve our comprehension of biological systems and define in greater detail invasion potential. This study explores the invasion of the guttural toad Sclerophrys gutturalis in Cape Town through a multidisciplinary approach that integrates physiology, evolutionary biology, ecological modelling and environmental economics. The species is domestic exotic in South Africa, being native in most of the country but not in Cape Town, where an invasive population established in 2000. Although an extirpation program (started in 2010) removed some thousand adults, tadpoles and eggs until 2016, the population is still spreading. Invasion dynamics emerging from traits of the invader and characteristics of the invaded landscape are unknown. -

The IUCN Red List, which determines the risks of extinction to species, plays an important role in guiding conservation activities of governments, NGOs and scientific institutions, and is recognized worldwide for its objective approach. In order to produce the IUCN Red List of Threatened Species™, the IUCN Species Programme, working together with the IUCN Species Survival Commission (SSC) and members of IUCN, draw on and mobilize a network of partner organizations and scientists worldwide. One such partner organization is the South African National Biodiversity Institute (SANBI), who, through the Threatened Species Programme (TSP), contributes information on the conservation status and biology of threatened species in southern Africa. -

4.4 Possible Impacts of Proposed River Club Development
South African astronomical observatory: vegetation and conservation 4.4 Possible impacts of proposed River Club development on the renosterveld of the SAAO site Dr Liz Day’s report on the wetlands of the River Club (Day, 2015) says the following: “The Flood Report of Krige (2015) (in Day, 2015) suggests that infilling of the entire River Club site to the 1:50 year flood level would not affect flooding in adjacent properties. Subsequent discussions with Mr Krige clarified the fact that infilling of the floodline would have an (as yet) unquantified effect on floodplain capacity, resulting in likely more rapid inundation of areas below a specified floodline, during an event of such a magnitude (as a result of reduced storage capacity). It is assumed that, up to floods of a magnitude at which flows bypass the constricting Salt River bridge, described in Krige (2015), infilling of the floodplain would also result in increased inundation depth in areas that have not been infilled”. There would be no impacts on the dryland renosterveld vegetation at the SAAO site (the water levels would be constant). However, as articulated by Day (2015) there is possibility that certain wetlands would be more quickly inundated, along with an increase in inundation depth. This would likely affect the species composition of localised wetland habitats, where deeper water species such as Typha capensis bulrush are likely to invade at the expense of those species with a more ephemeral wetland character. By comparison, the artificial perennial inundation of the Kuils River wetlands has led to the decline and even loss of certain wetland species in the area (Ninham Shand, 1999; Low, 1998). -
