Herseler Werth, Protected nature reserve in Bornheim, Germany
The Herseler Werth nature reserve extends across 14.8 hectares on a Rhine island between the metropolitan areas of Bonn and Cologne.
A significant Rhine flood between 1202 and 1237 reshaped the landscape by eroding parts of Hersel, leading to the formation of this island.
The reserve functions as a research site for scientists studying endangered species listed in the Federal Republic of Germany's Red List.
The area remains closed to public access, requiring special permits for entry, while strong river currents near the banks create hazardous conditions.
A 500-kilogram World War II bomb discovered during low water conditions in 2009 required evacuation of nearby areas for controlled detonation.
