Atop this gentle hill stands Honigbuck a place steeped in history. Honigbuck isn’t just a hill it’s a protected nature reserve. Designated on December 10 1963 it boasts 75 hectares of biodiversity. This area is part of the Freiburg Bucht a natural region in Baden-Württemberg.
The Honigbuck also known as Hunnenbuck meaning “Hun hill” has a fascinating geological history. It formed as a result of the sinking of the Upper Rhine Graben. This created an island-like fracture block. The hill is composed of Hauptrogenstein a type of Jurassic limestone. It’s topped with a layer of loess. The name Hunnenbuck is actually a misconception. People once believed it was a man-made structure perhaps a burial mound.
However the true story of Honigbuck is far more enchanting. Its rich calcareous soil supports an incredible variety of trees. Eleven different species thrive here including majestic winter lime trees. These trees produce copious amounts of nectar during flowering season. This abundance of nectar is why the hill was named Honigbuck meaning “honey hill”. Other notable trees include sessile oaks and hornbeams. All three native maple species are also present. This variety shows the uniqueness of this microclimate. Sadly the ash dieback disease has affected the area. Since 2020 many ash trees have fallen. The Forestry Office leaves them where they lie encouraging natural decay.
Beyond the trees the undergrowth is equally diverse. Red dogwood privet and guelder-rose shrubs flourish. The unique soil nurtures many spring bloomers. These include the snowdrop which is under special protection. The rare blue star and arum lily also thrive here along with wild garlic. Rare orchids like the white wood hyacinth also grow in this area.
