Tannenbusch Dunes

Tannenbusch Dunes is a protected nature reserve with sandy soil and sparse vegetation spanning seven hectares within an urban residential area of Bonn. The terrain displays typical dry grassland characteristics with drought-adapted plants and open sand surfaces.

The dunes formed around 10,000 years ago when strong winds transported sand from the Rhine River, creating a structure originally 600 meters wide. These natural processes shaped one of the few surviving inland dunes in the region, now placed under protection.

The reserve serves as a learning space where schools and kindergartens engage with local ecology and build understanding of specialized ecosystems. Visitors experience how communities value and protect rare habitats within their neighborhoods.

Visitors must stay on marked paths and keep dogs leashed to protect the delicate sand habitats. It is important to remove pet waste and leave the site in its natural condition.

The area supports rare plant species such as sand vetch and silver grass that depend on specialized habitats. These plants are found in few other places and demonstrate how valuable this small site is for regional biodiversity.
