Methods

The Coordinated Waterbird Counts (CWAC) project was launched in 1992. The objective of CWAC isto monitor South Africa's waterbird populations and the conditions of the wetlands which are important forwaterbirds. This is being done by means of a programme of regular mid-summer and mid-winter censuses at alarge number of South African wetlands. Regular six-monthly counts are conducted; however. we do encouragecounters to survey their wetlands on a more regular basis as this provides better data. CWAC currently monitorsover 400 wetlands around the country on a regular basis. and furthermore curates waterbird data for close to600 wetlands. Unit of abundance = Count, Unit of biomass = NA
