Water cascades down a rocky crevasse surrounded by a dense evergreen forest in park Eta. The whitewater is cascading from a large reservoir in the preserve. Everything within the borders of the park is part of a regional biotope, which is somewhat similar to a habitat, but the emphasis here is on a comunity interaction between various organisms. And in this park Humans are part of that community. So park Eta combines scenes such as this rolling river with villages, farms and tourist facilities, unlike a wilderness reserve that is mostly set aside as a pristine natural environment. Park Eta strives to maintain a balance betweeen commerce and countryside with smart sustainability practices.
