Kalkalpen_National_Park
Kalkalpen National Park (in English literally Limestone Alps National Park) is a national park within the Northern Limestone Alps mountain range, located in the state of Upper Austria, Austria.[2] The park was established in 1997. The ancient beech forests within the national park were added to the UNESCO World Heritage Site known as Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe, because of their undisturbed nature and testimony to the ecological history of Europe since the Last Glacial Period.[3]
