Watch Nature's Architects (2025) : Full Movie Online Free What could the bison and the beaver have in common? Although they are two completely different species in appearance, they have one remarkable thing in common: they create habitats that support the emergence and development of other animal and plant species. The bison and the beaver disappeared from Romania more than 200 years ago, and considerable efforts are now being made to reintroduce them back into the wild. This film tells the story of these two nature architects and talks about the many connections between these animals, their environment and the benefits to humans.
