The Slovak Europa issue in 2011 is dedicated to the National Park Poloniny.
This park is the eastern-most Slovak large protected area. It lies on the Slovak-Polish-Ukrainian border. The forests are dominant in the national park - they cover more than 90% of the area. Those most precious ones are declared to be the national natural preserves or natural preserves to protect the old forest community. They are unique for human-impacted or only slightly impacted forests called primeval forests. It is a community where everything flows in an integrated circle. It represents the peak of natural ecosystems.
