New habitats for more biodiversity - Benjes hedge and sandarium completed in Witzenhausen

Two projects to promote biodiversity on the Witzenhausen campus were completed in 2024: A Benjes hedge and a sandarium with a specially designed area for reptiles. The Benjes hedge provides valuable protection and nesting space for numerous insects, birds and small mammals. The sandarium creates important structures for wild bees, heat-loving insects, lizards and other reptile habitats that are increasingly being lost in our cultivated landscape.

In Witzenhausen, a measure was implemented on the Nordbahnhofstraße campus to improve the living conditions for the existing large trees. The Nordbahnhofstraße campus is characterized by large lawns with old individual trees. Old, large trees are also suffering from the effects of climate change and heat stress. To preserve them, seven trees at the Nordbahnhofstraße site were renovated and optimized using a compressed air injection process. This involved using purified compressed air to loosen the soil to a depth of 120 cm and injecting soil additives as air capacity builders, long-term water reservoirs and ion exchangers in the same operation. This improves the soil structure, promotes root activity and strengthens the health of the trees.
