This diversity of flora and fauna continues to be studied, and over 17,000 taxa have been identified, of which over 900 are endemics. Some of the largest remaining European populations of threatened mammals (such as the brown bear, the wolf, the Balkan lynx, the chamois, and bats), as well as the European populations of birds of prey, survive in the mountains and gorges of the protected areas, which is a direct reflection of the quality of composition and area remaining intact. The country thus offers great potential at the European scale for conserving species on the continent. Lake Ohrid is a UNESCO World Heritage Site.
