geography

Allee in the Erletal near Endingen

The Erletal is located in the northeastern Kaiserstuhl near Endingen . It leads south from the city up to the Katharinenberg ( 492.4  m above sea  level ). To the west of the valley is the Nahe valley, which leads to the Amolterer Heide . On the southern edge and between these valleys, on the foothills of the Katharinenberg, small remains of the Koliburg wall can be discovered at a good 360  m .

At the southern exit of Endingen is the Erleweiher, a natural pond (approx. 60 × 60 m) with a bathing area, a non-swimmer area and various sports facilities.

From the rental company, an avenue of more than 100 chestnuts stretches along a few other sports fields through the valley to the nature reserve, which is about 1.7 kilometers from the city center.

Erl hole

Erleloch (west)

The Erleloch, near the protected area and before the ascent to the Katharinenberg, is a 100 meter long tunnel and former drinking water canal and leads from the Erletal east through the Brüstleberg into the parallel Riedbach valley. When the supply of drinking water to the city of Endingen from the springs in the Erletal was no longer sufficient, this channel was dug in 1788 so that springs from the Riedbach valley could be used. The tunnel is lined with red sandstone at the entrance and exit and fixed with stones inside. The almost head-high tunnel can be entered today.

Protection purpose

The protection purpose "is the preservation of a wetland as a habitat for several rare and endangered plant communities with numerous threatened plant species."

Geology and development

In this basin, the loess that was blown up during the ice ages led to an accumulation of the clayey components and thus the development of a densely layered and less impermeable layer, which results in a continuous damming of the water by precipitation. This favored the emergence of forests with black alder and larger wetlands such as wet meadows . With expansion of settlement areas and intensification of agriculture since the 1950s, in the adjacent valleys, such as. B. in the Riedbachtal, the last remaining wetlands in the Kaiserstuhl drained and destroyed.
