Berchtesgaden Alps Biosphere Reserve, Biosphere reserve in Berchtesgadener Land, Germany.

The Berchtesgaden Alps Biosphere Reserve covers 840 km², matching the whole Berchtesgadener Land district, which reaches in a peninsula shape into the Austrian state of Salzburg. Its core zone is the 210 km² Berchtesgaden National Park; the care and buffer zone covers 69 km² and the development zone 632 km². The landscape holds deciduous and mixed forests, alpine pastures, high heaths, bogs and floodplain woods, plus a few villages and hamlets.

On 7 May 1974 the Bavarian state government approved the Berchtesgaden Biosphere Reserve, also called Alpenpark Berchtesgaden, with a national park as its core; its ordinance followed on 18 July 1978. UNESCO awarded the reserve its biosphere label on 20 November 1990, when it covered 467 km². In June 2010 it was enlarged to 840 km² and renamed Biosphärenreservat Berchtesgadener Land, now matching the district's borders.

The mountain villages in this area maintain traditional crafts and farming practices that have shaped the region for generations. You can see these customs reflected today in the carefully managed alpine meadows and in the local architecture.

Several information centers throughout the communities provide orientation and explain conservation goals. Visitors can find guidance about hiking and activities that allow respectful exploration of the natural areas.

The area connects high mountain ecosystems with adjoining foothills to create a cohesive protected landscape. This integration allows visitors to experience different elevations and habitats within a single region.
