The oldest trees of the Carpathian Forest self-seeded even 300-400 years ago. Their clusters are oases of unique plant and animal species, from mosses and lichens, insects to large mammals, including predators (wolves, bears, lynx and wildcats). The wildest part of the Eastern Carpathians lies on the border of Przemyśl Foothills and Sanok-Turka Mountains. WWF Polska and the Natural Heritage Foundation are campaigning for covering a large portion of the forest with reserve protection, and in the future - creating Turnicki National Park. They alert that the forests are threatened with logging and construction of roads.
