In nature reserve the Gelderse Poort four otters will be added to strengthen the genetic basis of the national otter population. The first two animals were set free there tonight. The otters come from various German zoos and are not genetically related to the otters in the Netherlands. In recent years, the habitat for otters has improved because water has become cleaner and measures have been taken for the safety of otters on roads near bridges and other obstacles. ARK Nature and the World Wildlife Fund (WWF) have initiated this addition.
