Beavers reshape Giessen’s landscape, boosting biodiversity and climate resilience
Beavers have returned to Giessen, bringing noticeable changes to the local landscape. Their presence is boosting biodiversity and supporting climate adaptation efforts. Authorities are now working to balance these ecological benefits with the needs of residents and infrastructure.
The European beaver is strictly protected under Germany’s Federal Nature Conservation Act. In Giessen, the Department of Environment and Nature, alongside the Lower Nature Conservation Authority, oversees their protection. These agencies also address conflicts arising from beaver activity, such as disruptions to footpaths and cycle routes.
Beavers naturally reshape their surroundings by building dams that raise water levels. This creates ponds, wetlands, and varied riverbanks, which serve as vital habitats for other species. Their engineering work stabilises the local water balance, reducing flood risks and retaining moisture during droughts. The ponds formed by beavers act as nurseries for young fish and hunting grounds for dragonflies. Abandoned lodges provide shelter for small mammals like the least weasel. Rare birds, including the tree pipit and common snipe, have also returned to the area thanks to these new habitats. Beaver ecosystems rank among the most species-rich in Central Europe. One ongoing challenge involves the foot and cycle path along the Wieseck, which has been affected by beaver activity. The Lower Nature Conservation Authority, the City’s Environment and Nature Office, and Hessen Mobil are coordinating repairs. Construction is expected to begin in 2026, following ecological assessments and planning approvals.
The city aims to secure the beaver’s long-term presence in Giessen’s ecosystem. Public cooperation will play a crucial role in protecting these animals while managing their impact on infrastructure. The return of beavers has already led to measurable improvements in biodiversity and climate resilience.
