All biosphere reserves are organised into 3 inter-related zones.
These are the core zone(s) of strictly protected ecosystem, a buffer zone where limited human activity is permitted, and a transition zone where greater activity is allowed.
In the case of the Magaliesberg Biosphere Reserve there are two core areas : the Cradle of Humankind World Heritage Site and the protected environment of the Magaliesberg mountain range.
To identify where the zones are located, the simplest tool to use is Google Maps: https://goo.gl/Rf0p72
The darker colour denotes the core, while the palest colour is the transition zone.
