Summary

Description
Deutsch: Wernauer Baggerseen, Naturschutzgebiet, NSG Nr. 1.090, 1981.

Im Vordergrund sichtbar: Neckar im künstlichen Flussbett. Hinten: vierspurige Autostraße.

Bis Ende 19. Jahrhundert war der Neckarlauf kaum durch den Menschen beeinflusst. Bei Hochwasser war die als Weidegebiet genutzte, gänzlich unbebaute Talaue, überflutet. Dann setzte zuerst der manuelle, ab der Mitte des 20. Jahrhunderts der maschinelle Kiesabbau ein. Kiesgruben wurden zu Baggerseen, die schließlich die zwischen Köngen und Wernau breite Talfläche gänzlich umpflügten. Das Gesicht des Neckartals veränderte sich vollständig. Der Wasserlauf wurde zu einer schnell fließenden, schmalen Rinne ausgebaggert, auch um alle Hochwasser zu bändigen. Ab 1970 war die Kies-Ausbeutung nahezu erschöpft. 1981 wurde ein Teil des Tals zum Naturschutzgebiet deklariert und eine Pseudo-Renaturierung begonnen.
English: Wernauer Baggerseen, nature reserve since 1981.

Visible are the dredged Neckar and a four lane Motorway in the back.

To the end of the 19th century the Neckar was almost untouched. During seasonal high waters the settling-free river flats, used for livestock keeping, were flooded. Then the mining of river gravel began, first manually, by mid 20th century mechanically. Gravel pits turned into quarry ponds, which soon turned upside down the entire Neckar valley, which is relatively broad between Köngen and Wernau. The riverbed was dug and turned into a fast flowing, deep high-water trench. After 1970, when extractions became unprofitable, part of the valley was declared a nature reserve, a pseudo renaturation began and sure enough, many rare and endangered flora, migrating and residing species settled again.
