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.

Building of both research and management capacity are two of these elements. This inventory is an excellent baseline from which to begin addressing the development of capacity in both these areas within South Africa. South Africa is regarded as an African if not a world leader in the management of established invasive species. Programmes such as Working for Water have won numerous accolades for its approach to dealing with the threat of invasive woody plants and job creation. Currently, bio-control in South Africa is well resourced and produces excellent work and numerous scientific publications. Needless to say many of the experts and much of the scientific literature in South Africa is focused on these two areas. The inventory highlights the lack of expertise in the following: ● Prevention of the introduction of new invasive species.
