South African Coordinated Waterbird Counts
The Coordinated Waterbird Count Project monitors South Africa's waterbird populations and the conditions of the wetlands which are important for waterbirds. The species ocurence data are available at OBIS. The OBIS compiled data includes species name, individual count, lat/lon, and some environmental correlates like depth and salinity.
