The Animal Demography Unit (ADU) launched the Coordinated Waterbird Counts (CWAC) project in 1992 as part South Africas commitment to International waterbird conservation. This is being done by means of a programme of regular mid-summer and mid-winter censuses at a large number of South African wetlands. Regular six-monthly counts are regarded as a minimum standard; however, we do encourage counters to survey their wetlands on a more regular basis as this provides more accurate data. All the counts are conducted by volunteers; people and organisations with a passion for waterbird conservation. It is one of the largest and most successful citizen science programmes in Africa, providing much needed data for waterbird conservation around the world. Currently the project regularly monitors over 400 wetlands around the country, and furthermore curates waterbird data for over 600 sites.
