The current condition and trend of biodiversity has recently been assessed as part of the Millennium Ecosystem Assessment (MA): averaged across all terrestrial species of plants and vertebrates, it is estimated that about 84 percent of the pre-colonial populations of wild organisms persisted in the year 2000. The rate of decline in “biodiversity intactness” was about 0.8 percent per year for the 1990s. Most of the organisms that persist occur outside the comprehensive and generally well-run system of protected areas. The various species of fauna and flora found in the vast range of terrestrial, freshwater and marine ecosystems are an important source of food, medicines, research and regional integration through transboundary conservation. They are also an important source of income for communities through community-based natural resource management (CBNRM) programmes.
