Trerichsweiher / Untere Aggeraue

Trerichsweiher and the lower Agger floodplain form a protected reserve with marshes, ponds, meadows and wooded sections along the river. The mix of wet and dry zones creates different habitats for plants and animals within a compact area.

The area received protected status in 1988 to preserve its wetland habitats and biodiversity. Additional regulations were introduced in 2005 to strengthen conservation efforts in this region.

Birdwatchers and nature photographers regularly visit to observe and document rare species found here. The location has become a gathering place for locals interested in studying wildlife in their region.

Several walking trails crisscross the reserve, allowing visitors to explore different sections at their own pace. Signage and information boards on-site help with navigation and explain the various habitats.

The river area attracts rare visitors like kingfishers and peregrine falcons that hunt and fish here. Many visitors consider spotting these birds a memorable highlight of their visit.
