Tussen april en oktober 2009 werden in 'De Kalkense Meersen' en 'De Viconiakleiputten' afwisselend tweewekelijks alle ganzen 's ochtends en 's middags geteld.

During the breeding season the observer walks at least twice the route that was mapped out in advance.There are 3 relatively brief periods: 10-25 April, 10-25 May, 10-25 June. During the walking of the route the observer stops for 5 minutes at a number of points (200-250m seperated from each other) and takes notes of all observed birds.
