Coordinated Waterbird Counts (CWAC)
CWAC started in 1992 with 45 sites counted in South Africa
Currently there are 645 wetlands registered with the CWAC project
1600 participants (~ 960 regular)Focus on waterbirds (~ 130 species)

Project Goal
To act as an effective long-term waterbird monitoring tool, benefiting
conservation efforts worldwide.

Project Objectives• Ensure effective project management through working closely with a host of national
and international stakeholders; steadily updating and integrating this network of people;
• Coordinate, prioritise and expand waterbird surveys on a national scale with the emphasis on long-term monitoring;
• Ensure effective data management throughout the project;• Manage, maintain and expand the project database;• Undertake effective IT development within the project, including the upkeep and
expansion of the project website;• Disseminate data and results through the project website, reports, scientific papers,
popular articles, direct liaison with stakeholders, or any other useful means;• Promote and facilitate the use of census data specifically for policy, planning and
research purposes;• Raise awareness and promote the project through the website, popular articles,
newsletters, interviews, talks, or any other appropriate means;• Submit census data towards the African Waterbird Census Programme in part
fulfilment of South Africa’s contribution to international agreements such as Ramsar, Bonn and AEWA.

Benefits of CWAC: an effective tool to…..
better understand how waterbirds use wetlands
fulfil S.A.’s commitment to international agreements (e.g. RAMSAR, CBD, AEWA)
ID important wetlands for waterbird conservation (e.g. roosts, breeding colonies, moulting refuges, Red Data species, etc.)
provide information support for management policies
assist national and regional population estimates
assist in monitoring the health of wetlands (waterbirds as indicators)
raise awareness of importance of wetlands as biodiversity hotspots
provide early warning of declines in populations and wetland degradation.

The future…• Improved coverage in poorly censused regions• Greater representation of wetland diversity
Seasonal pans Farm dams Rivers (linear densities) Palustrine wetlands (special surveys) Shore sections
• Collection of breeding data ID important sites Monitor breeding activity
• Data submission & availability Via Internet (on-line census form on ADU website) Automatic computerization Site & species information on website - data can be used!
![Page 22: COORDINATED WATERBIRD COUNTS. Coordinated Waterbird Counts (CWAC) CWAC started in 1992 with 45 sites counted in South Africa Currently there are 645 wetlands.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e425503460f94b353a4/html5/thumbnails/22.jpg)
The future… (contd.)• Site information
Basic wetland assessment:
• Wetland classification • Detailed habitat description• Detailed threat classification• Site management information• Fixed-point photography (habitat changes)
• Special surveys of secretive waterbird speciese.g. Rallidae and snipes
• More frequent monitoring at important sitese.g. RAMSAR & IBAs

Conservation outcomes
The future… (contd.)
• Catchment Management Plans (DWAF)• Other wetland programmes
SA Wetland Conservation Programme mondi Wetlands Project; SA Crane Working Group
• Setting sustainable hunting seasons & quotas• Environmental Impact Assessments (EIAs)• RAMSAR & BirdLife International programmes• International Waterbird Census (IWC) – Waterbird
Population Estimates (Rose & Scott; Delany & Scott)
