This Dutch video is about Wolven in Nederland. This organisation prepares for when wolves will come back to the Netherlands, trying to prevent human-wolf conflicts.
Translated from the Wolven in Nederland site:
The wolf which wandered in early March through Drenthe and Groningen provinces comes from a pack of wild wolves in Germany. It is a young animal from the “Munster” pack in the region of Hamburg-Bremen. This is shown by DNA analysis.
Early this month, the Netherlands was fascinated by a wolf of unknown origin, which for a few days ran through Drenthe and Groningen. The animal appeared regularly and behaved not exactly in a shy way. Research shows that it nevertheless was a wild wolf.
