Summary edit
| Description |
Afrikaans: Witborskormorante en bloureiers by die Wernause Baggermere, wat sedert 1981 'n verklaarde natuurreservaat is. Tot die einde van die 19de eeu was die Neckar byna ongerep. Tydens seisoenale hoogwaters is die onbewoonde riviervlaktes, wat as weigebiede benut is, oorstroom. Toe begin die ontginning van riviergruis, aanvanklik met hand en graaf, en teen die middel van die 20ste eeu meganies. Gruisgate het in steengroefdamme verander sodat die hele Neckar-vallei, wat tussen Köngen en Wernau betreklik breed is, weldra omgedolwe is. Die Neckardal se voorkoms het 'n omwenteling ondergaan. Die rivierbedding is gebagger en in 'n diep, vinnigvloeiende hoogwaterkanaal omskep. Na 1970, toe die gruisgroewe onwinsgewend geword het, is 'n deel van die vallei tot 'n natuurreservaat verklaar. 'n Pseudo-hernaturering het begin en verskillende skaars en bedreigde flora, benewens immanente en migrerende dierspesies, het hulself hervestig.
Deutsch: Wernauer Baggerseen, Naturschutzgebiet, NSG Nr. 1.090, 1981.
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.
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. |
