The growth of the "new" South Africa and the development and upliftment of the South African people requires that many issues be addressed over the next few years. These issues range from the provision of water and other amenities, both for industrial as well as human needs, to the provision of employment and generation of wealth, through rapid economic growth. However, rapid development and rapid economic growth are placing an ever increasing strain on the natural resources and environment of the country. GIS-based management tools are being developed at a national level to support decision making and policy, as well as at a local level to support day-to-day management and research within catchments and management areas. This paper describes a number of the GIS management tools developed by Environmentek over the last year. These tools include, the Conservation Management System a catchment/reserve level fire and alien weed management tool, the National Nature Conservation Information System, a national level decision support tool, the Open Areas Management System, a simple tool for managing permanently unplanted areas within plantations, as well as a number of PC-based tools for supporting land-use planning and plantation management.
