KALKALPEN NATIONAL PARK

AUSTRIA'S FOREST NATIONAL PARK

The Kalkalpen National Park protects Austria's largest contiguous forest wilderness. It is the most important forest national park in the Alpine region. The protected area includes the Reichraminger Hintergebirge and the Sengsengebirge in the south-east of Upper Austria. Its varied and closely interwoven habitat mosaic, consisting of around 30 types of forest, is the foundation of a high level of biodiversity. More than 10,000 species of animals, plants and fungi, including highly demanding primeval forest relict species, can be found in the various forests. By abandoning human use, dismantling infrastructure and removing obstacles to the free flow of natural processes since its establishment, the future prospects of high-ranking protected species in the 16,000-hectare, non-intervention natural zone have improved enormously.

Back to the primeval forest

Like all forests in the Enns and Steyr valleys, the former forests in today's Kalkalpen National Park have been used since the early Middle Ages. The wood was turned into charcoal in charcoal kilns, as the numerous scythe, knife, hoe and hammer forges needed huge quantities of it. The original forests were thus wiped out except for small remnants. The remaining islands of primeval forest provide a habitat for highly endangered relict forest species, especially those that depend on lush dead and old wood and natural forest dynamics. 15,000 hectares of National Park Forest have been designated as a biotope protection forest in accordance with Section 32a of the Forestry Act. Since then, everything has changed. Only nature is allowed to reign unrestricted in the nature zone. The forest may be restored in a process lasting several centuries primeval forest .

Our natural heritage

The Kalkalpen National Park impresses with its wild forests, hidden gorges and panoramic mountain peaks. It is home to rare animal species. The ancient beech forests are recognized as a UNESCO World Heritage Site. Water is another valuable treasure. Over 800 springs feed the longest natural stream system in the Northern Limestone Alps.

Ancient beech forests and primeval beech forests in the Kalkalpen National Park

With its valuable old forests and primeval beech forests, Kalkalpen National Park is the most important forest national park in the Alps. The older the forest, the richer its life. More than 10,000 species of animals, plants and fungi can be found in the various types of beech forest. With an area of 5,252 hectares, Kalkalpen National Park is not only the largest beech forest reserve in the Alps, but also the oldest beech tree with a proud age of over 550 years.

The international position of the Kalkalpen National Park

While the national development of the protected area, from the former Sengsengebirge nature reserve to the official opening of Kalkalpen National Park in 1997, took a long time and required many compromises, international recognition followed extremely quickly. As early as 1998, Kalkalpen National Park was recognized as another protected area by the IUCN - the World Conservation Union. Since then, the national park administration has been implementing the strict requirements of IUCN Category II, which contains the definitions for "national parks".

The nomination of Kalkalpen National Park as a Natura 2000 site (EU), initiated by the nature conservation authority, caused less excitement. In 2004, it was included in the list of "Protected areas of Community importance for the Alpine region" and subsequently implemented as a European protected area under national law. Also in 2004, Kalkalpen National Park received another international award, namely as a Ramsar protected area, also the first in Austria with the category "karst water". The Ramsar Convention is a transnational "Convention on the Protection of Wetlands of International Importance". In 2017, UNESCO declared 5,250 hectares of beech forest wilderness a World Heritage Site.

Karst in the Kalkalpen National Park

Around three quarters of the national park is karstified and the karst is a special feature in many respects. Over geological periods of time, the limestone in the subsoil was dissolved by seeping rainwater and a highly complex and branched network of cavities, extended fissures and caves developed in the mountains of the national park, especially in the Sengsen Mountains. Such a karst landscape is a highly volnerable system in which surface impurities can penetrate the groundwater body almost unhindered. An incredible number of springs drain the wilderness areas, and there are often several storeys of spring outlets on the slopes. Some of these giant karst springs only burst during flood events - but then pour out huge quantities of up to several cubic meters per second. This extreme water dynamic is typical of the karst region at Kalkalpen National Park.
