General character of the site The striking scenery with wooded hilltops in this area close to Bonn, Königswinter and Bad Honnef is the result of volcanic activity and erosion. The Siebengebirge can be described as the wreck of a great volcano which erupted at several different points. The present 300-400m summits consist of solid rock from which the tuffs were removed by erosion. Much of the reserve comprises beechwood communities with xerothermal features characteristic of oakwood with hornbeam. 
Vulnerability The forest area is likely to be crossed by new road and rail routes; the pressure of tourism is felt in places, for example the Drachenfels. Forest die-back continues; it is planned to reduce the conifer acreage, increase the proportion of the characteristic broadleaved species and preserve islands of ancient woodlands and copices. 
Owner The reserve is the property of the Land of North Rhine-Westphalia, the Verschönerungsverein, the council of Honneftown and various private owners.
