Hohe Artenverluste in der Kulturlandschaft Nord- und Mitteldeutschlands

Forscher aus Göttingen und Görlitz untersuchen Entwicklung der Artenvielfalt über Jahrzehnte

(PresseBox) (Göttingen, )
Die Intensivierung der Landwirtschaft in den vergangenen Jahrzehnten hat zu einem hohen Verlust der Artenvielfalt in den Kulturlandschaften in Nord- und Mitteldeutschland geführt. Das haben Wissenschaftler der Universität Göttingen in Zusammenarbeit mit dem Senckenberg Museum für Naturkunde in Görlitz herausgefunden. Auf rund 1.000 Untersuchungsflächen - Ackerland, Grünland und Fließgewässer - wiederholten die Forscher Vegetationsaufnahmen aus den 1950er- und 1960er-Jahren, um den Wandel zu analysieren.

Dabei stellten sie unter anderem fest, dass die Fläche artenreichen Grünlands auf frischen bis feuchten Böden in den vergangenen 50 Jahren um rund 85 Prozent abgenommen hat - heute dominieren artenarme intensiv gedüngte Grünländer.
