On 28 July, 2005 a student from Germany took a picture of a bear in the Swiss National Park, the first bear in Switzerland in100 years!
Since then every year some single young males from the Tentino bear population wander into Switzerland. Until now these were always temporary visits.
Bear monitoring in Switzerland takes place opportunistically by means of reported chance observations and genetic analysis of samples for individual identification. In special cases – especially for intrusive bears which are likely to be scared off – the department of Game and Fish of the canton Grisons puts radio collars on the bears and thus a lot of informative movement data is gathered.
