Ilvericher Altrheinschlinge, Nature reserve in Meerbusch, Germany

The Ilvericher Altrheinschlinge is a nature reserve that stretches along the old Rhine riverbed with wetlands, grasslands, and forests creating a patchwork of habitats. The land takes its form from the former river course and the different ecosystems that develop in such settings.

The loop formed about 11,000 years ago at the start of the Holocene, when the Rhine became a strongly meandering river. Around 7,000 years ago the river broke through the narrow neck, leaving the loop as a side arm; by about 3,000 years ago it silted up into a still water and then a fen. After a dike breach on 16 January 1920 the area was flooded for the last time.

Farmers work the land within the reserve while maintaining traditional methods that fit naturally with the surrounding environment. This relationship between agriculture and nature shapes the character of the area today.

Access is through marked trails that lead to viewing areas for observing wildlife and natural features. Sturdy footwear is useful since the ground can be wet or muddy depending on the season.

The reserve preserves scattered blocks of brown coal quartzite that are protected as natural monuments. These stones stand as reminders of ancient geological processes and can be spotted throughout the landscape.
