This spring a Belgian researcher in the Kempen-Broek has recorded an otter on a camera three times. The Kempen~Broek is a large cross-border nature reserve between Maaseik (Belgium) and Weert (the Netherlands) in Limburg. The otter has been seen in the Smeetshof marsh, restored ten years ago and owned by the Belgian nature organization Natuurpunt. This is the first certain sighting of an otter after almost 50 years in the Limburg provinces (both Dutch and Belgian).
Japanese otter declared extinct: here.
