Hidden within the Königsforst forest southeast of Cologne lies the Großer Steinberg. This isn’t just any forest. It’s a Naturwaldzelle a designated nature reserve. Imagine a place untouched by human intervention. A place where nature reigns supreme. This is the Großer Steinberg.
Established in 2004 the Großer Steinberg covers 45.3 hectares. That’s significantly larger than the average Nordrhein-Westfalen nature reserve. It’s a haven for biodiversity. It’s a place where the natural life cycle unfolds unimpeded.
The Großer Steinberg sits on the northern slope of the larger Große Steinberg hill. Its elevation ranges from 110 to 125 meters above sea level. This relatively flat landscape supports a unique ecosystem. The soil here is a fascinating mix of loamy sand and sandy loam. In the Selbach valley the ground is saturated. There you’ll find Niedermoor-Gley soil and Niedermoor-Torfe peat. On higher slopes you’ll find Pseudogley-Braunerde and Braunerde.
The Großer Steinberg is part of a larger protected area. It is within the Königsforst nature reserve and a Natura 2000 site. This means it’s part of a European network of protected areas. Scientists meticulously monitor individual trees within the reserve. They observe the natural processes within this unique ecosystem.
The forest itself is a mix of beech trees oaks and other deciduous and coniferous species. Without human interference the Großer Steinberg would likely become a Hainsimsen-Buchenwald a type of beech forest. In 2005 some of the beech trees were 75-85 years old. There were also some much older approximately 185-year-old oak trees. The Großer Steinberg is a living laboratory. It helps scientists understand the natural development of forests. It serves as a reference for ecological forest management in Nordrhein-Westfalen. It’s a testament to the power of nature. It’s a place of quiet beauty and scientific importance. It’s a place where you can connect with the natural world. This is the Großer Steinberg a small corner of wilderness. It’s a vital part of Cologne’s natural heritage.
