The Carpathian Mountains or Carpathians are a range of mountains forming an arc roughly 1,500 km (932 mi) long across Central and Eastern Europe, making them the second-longest mountain range in Europe (after the Scandinavian Mountains, 1,700 km (1,056 mi)). They provide the habitat for the largest European populations of brown bears, wolves, chamois and lynxes, with the highest concentration in Romania, as well as over one third of all European plant species. The Carpathians and their foothills also have many thermal and mineral waters, with Romania having one-third of the European total.
