The map below shows the Freshwater ecosystem Priority Areas for river ecosystems in South Africa with particular focus on river condition (RIVCON). RIVCON is divided into the following categories: A = unmodified and natural, B = Largely natural with few modifications, AB = A or B above, C = Moderately modified, D = Largely modified, E = Seriously modified, F = Critically/extremely modified, EF = E or F above, Z = Tributary condition modeled as not intact, according to natural land cover.
