The temporal an spatial patterns of the regression were investigated by a quantitative evaluation of aerophotos. Nine hypotheses were tested whether they could explain these patterns. As a result it was confirmed that the "pelagic eutrophication", the "nutrient enrichment of the reedbed sediments" and the "existence of detrimental redox conditions in the upper sediment layers" are no convincing concepts. Damage of the lakeside reedbelts by a f100d disaster, two heavy storms and a hailstorm in June 1965, have been found to be the only factors which coincide with the patterns of the regression. As a consequence, the concept of reedbelt management and maintenance should be modified, giving more protection against mechanical damage and bank erosion.</dcterms:abstract> <dc:language>deu</dc:language> <dcterms:alternative>The causal factors of reed decline in Lake Constance-Untersee (West-Germany)</dcterms:alternative> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/8642"/> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:45:20Z</dc:date> <dc:format>application/pdf</dc:format> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:45:20Z</dcterms:available> <dcterms:title>Die Ursachen des Röhrichtrückgangs am Bodensee-Untersee</dcterms:title> <dc:creator>Ostendorp, Wolfgang</dc:creator> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
