Freshwater ecosystem Priority Areas - River Condition

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.
