The European bison disappeared from Romania around 200 years ago, mainly due to hunting and habitat loss. Since 2014, Rewilding Europe and WWF Romania - who co-commissioned Zimbrul - have been working together in the Southern Carpathians rewilding area to reintroduce this iconic species. Portraying the acceptance of bison by people in the area, and their changing perceptions of wild nature, the film demonstrates why the positive involvement of local communities is so critical to the success of rewilding efforts.
