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. -
Indigenous Fish Fact Sheet
FACT SHEET What a landowner should know about the INDIGENOUS FISH of the Cape Floristic Region: DIVERSITY, THREATS AND MANAGEMENT INTERVENTIONS The majority of the freshwater The Cape Floristic Region, mainly within the Western Cape Province, fish of the Cape Floristic is one of the six plant kingdoms of the world. This area, however, is Region are listed as either not only home to a remarkable number of plant species but also has a Endangered or Critically Endangered and face a very number of unique indigenous freshwater fish species. real risk of extinction! INDIGENOUS FISH are a critical component of healthy aquatic ecosystems as they form an important part of the aquatic food web and fulfill several important ecological functions. These fish need suitable habitat and good quality water, free of sediment and agrichemicals, in order to survive. The presence of indigenous fish is one of the signs of a healthy riverine Cape kurper ecosystem, making indigenous fish good bio-indicators of healthy rivers. There are four main river systems in the Western Cape, namely the Berg, Breede, Gourits and Olifants, and each system has unique fish species which only occur in ecologically healthy parts of these rivers. A good example is Burchell’s redfin in the Breede and neighbouring river systems. Genetic research on this species indicates that there could be three distinct species in the Cape galaxias Breede system. The Olifants River system is however recognised as the hotspot for indig- enous fish diversity as this system has the highest number of unique indigenous species. Research is ongoing and further genetic diversity is being uncovered for other species such as the Cape kurper and the Cape galaxias. -

Invasive Alien Flora and Fauna in South Africa: Expertise and Bibliography
Invasive alien flora and fauna in South Africa: expertise and bibliography by Charles F. Musil & Ian A.W. Macdonald Pretoria 2007 SANBI Biodiversity Series The South African National Biodiversity Institute (SANBI) was established on 1 September 2004 through the signing into force of the National Environmental Management: Biodiversity Act (NEMBA) No. 10 of 2004 by President Thabo Mbeki. The Act expands the mandate of the former National Botanical Institute to include responsibilities relating to the full diversity of South Africa’s fauna and flora, and builds on the internationally respected programmes in conservation, research, education and visitor services developed by the National Botanical Institute and its predecessors over the past century. The vision of SANBI is to be the leading institution in biodiversity science in Africa, facilitating conservation, sustainable use of living resources, and human wellbeing. SANBI’s mission is to promote the sustainable use, conservation, appreciation and enjoyment of the exceptionally rich biodiversity of South Africa, for the benefit of all people. SANBI Biodiversity Series publishes occasional reports on projects, technologies, workshops, symposia and other activities initiated by or executed in partnership with SANBI.
