The Sieg nature reserve is a 617 hectare area in the course of the Sieg , which is under the protection of Natura 2000 and is registered with the number DE-5210-303. The area includes the Mitteliegtal as a winding valley between Fürthen and Troisdorf .

The river Sieg, which often flows through the grassland valley and is relatively close to nature, has in parts rock fillings as bank reinforcement, on the other hand there are sometimes natural gravel banks in front of it. Often, dense riparian woodland predominantly made up of tree willows, willow bushes and ash trees, as well as riparian vegetation, mark the course of the river in the grassland floodplain. In the floodplains are oxbow lakes, which are often overgrown with alder floodplain forests.
