Wetlands changes in the landscape of lowlands and uplands of the Czech Republic over the last 180 years

Popis výsledku v původním jazyce

This paper presents results of study focussed on wetland changes in the lowland and hilly areas of the Czech Republic over the last 180 years. The main objective of this study was to test a methodology for analysing historical development of wetlands in the lowland and hilly areas of the Czech Republic, with emphasis on their spatio-temporal changes in the landscape. And with focus on the use of well-suited for GIS analysis and available archive maps to provide an overview of the historical location of wetlands. The sources used for the study included historical maps from the Stable Land Registry, a current orthophoto maps (2015-2017), the DIBAVOD database, the LPIS (Land-Parcel Identification System) database and field mapping (2015-2017). Three basic wetland biotope types were examined: wet meadows, wet meadows with woody vegetation, and marshes or swamps. Spatial analysis by using GIS tools were performed to analyse the spatio-temporal wetland changes. The total wetland area has decreased dramatically from 5,762 ha (over 9.5% of the territory included in the study) in 1825-1843 to 54 ha (0.9%) in 2015-2017. Extinct wetlands predominate (99.1%) in the area, while the shares of recent and continuous wetlands are nearly identical (0.5% and 0.4%, respectively). Further, the changes of wetlands on agricultural land in selected localities from this study, were described in more detail. The results of this study document fundamental spatio-temporal changes of wetland biotopes at the landscape level in the lowland and hilly areas of the Czech Republic. The most frequent change type is wetland loss in favour of arable land due to extensive agricultural management. The results of the study contribute substantially to the development of methods for the investigation of spatio-temporal changes in wetlands in the context of the landscape.
