The wolf which this spring briefly visited the Netherlands was killed. On April 15, a dead wolf was found on the A7 motorway at Berkhof in Germany. DNA research has shown that this was the same animal which visited the Netherlands and Lower Saxony, say Landesjägerschaft Lower Saxony and Lower Saxony Wolfsbüro.
Research shows that the animal was killed by a truck.
