Kruger to Canyons biosphere reserve

 

General description

Kruger to Canyons Biosphere Region, covering 2,474,700 hectares, is located in the north-east of South Africa. It encompasses the Kruger National Park as well as other National and Provincial Nature Reserves such as the Blyde River Canyon Nature Reserve. Three of the Southern African biomes are incorporated into the biosphere reserve, including the grasslands and Afro-montane forests, and the savanna of the lowveld. There is a high level of biodiversity, especially plant endemism on mountain tops.

Approximately 1,5 – 1,6 million people live in the area (1996). Alongside the extensive tracts of conservation areas there are large, rural developing communities living on tribal land, where many of the natural resources have been over-utilized. There are a number of different land use practices in the region including mining for gold, phosphate and copper, the plantation of exotic species and the extensive cultivation of subtropical fruits and vegetables. It is hoped that through the establishment of the biosphere reserve framework and the establishment of partnerships, the quality of life can be improved for the majority of the people and that the integrity of the conservation areas will be secured. Local communities and authorities already have rallied together under the biosphere reserve framework to promote eco-tourism and the maintenance of cultural values.
