East Carpathians Biosphere Reserve stretches across three countries, Poland, Slovakia and Ukraine and constitutes one of the best protected areas for endemic and threatened animals. The part in Slovakia is Poloniny National Park, the only national park in Eastern Slovakia. The national park contains not only the primeval forests, but also normal villages and a huge reservoir. People who have lived in this area own their houses but share half of the land with the council and can do whatever they want to the house. Unfortunately, people still intend to move out of the most eastern end to big cities to earn their living.
