The accompanying map simplifies a range of biodiversity information into four categories of decreasing sensitivity to mining: ‘Legally protected', ‘Highest biodiversity importance', ‘High biodiversity importance' and ‘Moderate biodiversity importance'. The guideline, map and spatial data are freely available online through SANBI's Biodiversity GIS website (http://bgis.sanbi.org). A large number training sessions have been held since the guideline was published, well attended by representatives of the private sector, government, academic institutions and nongovernmental organisations.
