Abstract: The manuscript presents maps of internationally important wetlands located in the Kis-Sárrét (Hungary) from 1860 to 2008. The study area is located in south-east Hungary, in the Körös-Maros National Park and covers 8048 ha. For the historic map review, we used digitized data of topographic maps from the period of two military surveys and the Second World War. We also made habitat maps of the area in 2007 and 2008. Data processing, and the establishment of a database of the mapped area, was made using QuantumGIS 1.7.0 and Esri ArcView GIS 3.2. Maps were produced using Esri ArcGIS 10.0 and show where and in what ratio the once extensive wetlands occurred, how they changed and in which part of the area they survived in different mapping periods. They provide a point of reference for the monitoring of wetlands, contributing to the long-term conservation of these valuable habitats. Maps and diagrams show that between 1860 and 1944 wetland extent decreased by half. The ratio of natural, ‘purely’ wet habitats reaches only 4.67% now. Wetlands typically occur in habitat complexes, therefore not ‘purely’ wet habitats (20.77%) also have to be taken into account. Considering this, and a recent habitat reconstruction, the extent of wetlands is more favourable today than it was in 1944. However, to sustain them requires care and well-planned management to which the maps presented here provide an important basis.
