The Ennert belongs to the Siegburg state forest and is part of the Siebengebirge nature reserve.

Before mining, the area was largely unforested and used for agriculture. Historical reports tell that at the beginning of the 19th century when hiking on the Ennert-Hardt, also known as Holtofer Hardt , you went to Holzlar via fields and there you had a wonderful view of Cologne Cathedral, Bonn and the Siegburg Abbey. After the site had become unusable for agriculture due to the mining of tunnels, massive earth movements and pollution from sulfur-containing emissions and the ash left behind from alum smelting, afforestation took place - one of the earliest recultivation measures ever.

The Teufelsbach and the Alaunbach , the creek with the poorest water quality in Bonn, collect wastewater leaking in the former mining and smelting area .
