There are other small habitats in the AuenLand, including a specially constructed wet trough. In the summer months in 2019, the trough was covered with plastic sheets to keep the water in small areas. Among other things, that allowed amphibian larva from the tree frog to develop. The nature discovery pond, measuring 25 by 15 meters, is home to different species of amphibians. In 2019, marsh marigolds and other wetland plants became established at the edge of the pond.
A dry stone wall provides a refuge and winter quarters for amphibians. Lizards also have been seen near the wall. Once all the construction work has been completed, sand lizards might settle in the nature discovery area, too.
