Long-term monitoring on waterbird populations of Kardoskút Fehértó
Since the designation of certain sites to the List of Wetlands of International Importance, decades have passed and the ecological state of them is constantly changing. Monitoring of ecological state is essential for determining the objectives for nature conservation management purposes. Waterbird populations have been widely used as indicator of the naturalness of wetlands, therefore running longterm projects of waterbird counts helps to formulate more effective nature conservation management. The 488 hectares large Kardoskúti Fehértó plays a significant role in bird migration hosting thousands of waders, ducks and geese. In this paper the result of waterbird monitoring between 1984 and 2006 are analysed. Maximal number of waterbird species increased in the study period. Significant changes in populations of Teal and Shoveler were found in the study period.
