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). 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.
