First bison for 400 years roam freely in Germany
A small group of bison has been released, in April 2013, into a 10,000 hectare forest in the Rothaar Mountains of North Rhine Westphalia.
One of the cows has since given birth to a male calf, and it is hoped the herd will grow to around 25 animals.
This release follows a long period of behavioural study, and assessment of the role of bison in the ecosystem as well as their impact on the forest itself. As a large herbivore they fill an important niche and help maintain a mosaic of different habitats - forest intermingled with shrub and grassland - that can support a more varied biodiversity.
Plans were recently proposed by the Rewilding Europe programme to reintroduce bison into the Southern Carpathians
