The Lobau forest area in Vienna is facing significant ecological challenges. Following an August 4 wildfire that damaged approximately 18 hectares, cleanup and safety operations have commenced. The City of Vienna Forestry and Agriculture Service is felling weakened trees along paths to protect pedestrians and cyclists, while using drones to survey damage and monitor for invasive species.

Simultaneously, the Lower Lobau, a protected area within the Donau-Auen National Park, is experiencing a severe drought crisis driven by heatwaves and historical river regulations that have cut the area off from the Danube. The WWF has described the situation as ‘extremely bad,’ noting that the lack of water threatens critical habitats. While water diversion has been used in the Upper Lobau for two years, the City of Vienna is currently evaluating potential measures for the Lower Lobau, pending groundwater flow models to ensure the local drinking water supply is not impacted.
