The Oostvaardersplassen in Flevoland is the largest national park in the Netherlands. 25 years ago they introduced some deer, Heck cattle and Konik horses and this park is a very good example of rewilding. Now there live about 1100 wild horses, the largest population in Europe. The Konik is originally a Polish and Belarusian small wild horse. They live in large groups with many foals and there is often a lot of interaction and even fights.
