One Year After Oil Spill at Thuer Wiesen - Fewer Dragonflies - Oil Spill Devastates Wildlife in Thuringian Meadows Nature Reserve

An oil spill in February 2025 near Thuringian Meadows nature reserve caused significant harm to local wildlife. The accident happened when a truck carrying 30,000 litres of heating oil overturned, sending oil into the rainwater drainage system. The spill particularly affected the reserve's expansion zone, where birds, amphibians, and insects faced severe consequences.

The spill occurred after the truck tipped over, releasing oil that spread into the drainage network. Emergency teams quickly responded, but the damage to wildlife became evident within days. Many birds, including waterfowl, were found covered in oil, unable to fly or maintain their body temperature. Their survival rates dropped sharply as a result.

Cleanup operations focused on the expansion zone, where large stands of reeds had to be removed. While soil and water tests in the core nature reserve showed no contamination, the expansion area suffered lasting effects. Environment Minister Katrin Eder later warned that the spill could have long-term consequences for the ecosystem.

By the following summer, certain dragonfly species had disappeared from the expansion zone. The full impact on amphibians, fish, and other aquatic insects remains unclear. Despite the disruption, one pair of white storks managed to breed successfully, raising three chicks in the affected area.

A year after the spill, the absence of specific dragonfly species highlights the ongoing environmental impact. The incident disrupted seasonal breeding patterns for birds and left uncertainties about the recovery of smaller creatures. Authorities continue to monitor the area as cleanup efforts progress.
