Marine mammals in Belgium
0 Reviews

The aim is to gather all Belgian marine mammal observations and strandings. The Royal Belgian Institute of Natural Sciences (RBINS) has been responsible for coordinating research into the strandings and cause of death of marine mammals in Belgium since the early 1990s. The institute produces annual reports on observations and strandings of marine mammals in Belgium with the collaboration of SEALIFE Blankenberge and the Universities of Liège and Ghent.

These reports describe a part of the implementation of the Royal Decree on Marine Species Protection, and its production is only possible thanks to the support of many volunteers, other institutions and  coastal authorities. Interested readers can download the report at (available in Dutch and French, with English summary).

Collecting data on strandings and sightings of marine mammals is important as such data can provide us with a lot of information about marine mammals, their population trends, problems they face, and eventually on the condition of the marine environment in general.
