Trajektorie vývoje mokřadů v horní části povodí Výrovky za uplynulých 180 let

The Trajectory of Wetland Development in the Middle Part of the Elbe River Basin in the Past 180 Years

“…In the category of disappeared wetlands, they are the most common type (Table 4). This fact corresponds to the fi ndings of similar studies in the Czech Republic and abroad [26,[28][29][30][31][32][33][34].…”

“…This area, however, is largely hilly and is known for its pond farming tradition. In both areas, however, the same result occurred; the dominant type of historical wetlands -wet meadows -had almost completely disappeared from the current landscape [33]. Wet meadows were also the dominant type of historical wetlands during the monitoring of changes in wetlands on the edge of Brdy Mountains.…”

“…However, especially in the middle part of Elbe River basin, where the Elbe River meandered in the past, the natural circulation of surface water and groundwater has been disturbed by human economic activity; as a result, wetlands are most often found in places overgrown with "wild" vegetation, which cannot be cultivated with modern technology without drainage, and so they are overgrown with both woody plants and reeds. The occurrence of swamps and marshes in Polabská nížina was expected, as this is indicated by the results of studies dealing with wetlands in the landscape of the lowlands of the Czech Republic [31][32][33]; however, such a dominance of this type of current wetland was not expected.…”

Povodí Výrovky jako vhodné území pro sledování a porovnávání hydrologických a krajinných charakteristik

“…O povodí Výrovky bylo v minulosti publikováno několik odborných článků, jež se zabývaly zejména historickým vývojem krajiny a změnou využívání území, resp. změnou lokalizace mokřadních biotopů [1][2][3]. Část povodí Výrovky byla zvolena jako jedna z řešených lokalit analyzujících změnu mokřadů v krajině nížin a pahorkatin České republiky [4].…”
