  1. Managing Fynbos Catchments for Water • 30 November 1993 • “Two initiatives were identified for the future. • Firstly, a promotional presentation or “roadshow” should be compiled and presented to local decision-makers, based on data, models and results presented at the workshop. The emphasis of the roadshow should be on water runoff and not so much on biodiversity. • Secondly, an international initiative should , on the other hand concentrate on the biodiversity side of the problem.”

  2. Prof Kader Asmal 23 February 2000 “Reinforced by the cogent arguments put forward by the WWF-SA, I approached my dear colleague, Jay Naidoo, for funding. ....... ....., so it is safe to confess that I approached Jay Naidoo for initial funding of R25million, without a business plan. Jay is a wise person, and he saw the value of what was being proposed. I cannot say that the rest is history, for we are still coming to grips with our strategies to deal with the threats posed by invading alien plants, let alone other invasive species.”

  3. Working for Water Mission Statement • The Programme will sustainably control invading alien species, to optimise the potential use of natural resources, through a process of economic empowerment and transformation. In doing this the programme will leave a legacy of social equity and legislative, institutional and technical capacity.

  4. To Achieve its Mission, the Programme has the Following Objectives: • HYDROLOGICAL  • To enhance water security through regaining control over invading alien plants in South Africa and to promote the quest for equity, efficiency and sustainability in the supply and use of water. • ECOLOGICAL • To improve the ecological integrity of our natural systems through the removal of alien plants thereby countering abnormal fires, soil erosion, flooding, scouring of rivers, siltation of rivers, dams and estuaries; and protect and restore biodiversity. • SOCIAL • To optimise the social benefits that are possible as a community-based public works programme by investing in the most marginalised sectors in South African society and enhancing their quality of life.

  5. Working for Water Mission and Objectives cont…. • NATURAL RESOURCES • To restore the productive potential of land, in partnership with the Land Care and Desertification initiatives, and to promote the sustainable use of natural resources. • ECONOMIC • To develop the economic benefits (from land, water, wood and people) from clearing these plants, by facilitating economic empowerment and the development of secondary industries, and to play its part in protecting the economic integrity of the productive potential of the country.

  6. The Invasion Process

  7. Alien plants were introduced from continents such as Australasia and South America.

  8. Present 10 yrs 20 yrs The possible extent and rate of spread of IAP over 20 years in a fire prone Fynbos mountain catchment.

  9. Management & Its Costs

  10. Clearing invading alien plants.

  11. * Data from Versfeld et al.3. + Total area recorded as receiving initial clearing plus follow-up divided by 2, and adjusted upwards for incomplete coverage in the project management system. # Area in South Africa divided by area treated in 2002/03.

  12. Bio ControlSavings of 20-30% could be achieved if biocontrol methods are used for woody species.

  13. Integrated Strategy Incentives or Disincentives Species Areas

  14. Hydrology

  15. RIPARIAN CLEARING EXPERIMENTSFlow measurement

  18. Biodiversity or Natural Diversity

  19. Hakea infestations in the Western Cape have smothered natural vegetation in many mountainous areas

  20. Loss of BiodiversityUp to a 1/4 of RSA’s plant species.

  21. Ecosystem Functioning & Services

  22. Port Jackson has spread throughout the Cape.

  23. Hakea infestations in the Western Cape have smothered natural vegetation in many mountainous areas

  24. Rehabilitated Riverine Forest Rehabilitated Riverine Forest

  25. The Higher the Plant Biomass the Higher the Cost of Fire Protection & Control - Controlled fire cycles An opportunity for economic development!!

  26. Loss of life, damage to land and property through high intensity fires.

  27. Impacts of High Intensity Fires Under Invading Alien Plant Stands

  28. Chapmans Peak drive above Noordhoek on 31 May 2000. Alien and cleared vegetation occurred on the slopes above this site.

  29. Impacts of Invading Alien Plants on Catchment Stability After Fires

  30. The use/(development??) of Natural Landscapes for Nature Based Tourism

  31. Human Resource Development

  32. It offers opportunities for women, the youth and the disabled

  33. Open Contract Open Market Closed Contract Managment & Production Incentive Piece Work Production Incentive Task Work Time Incentive Day Work
