The Ötztal region experienced significant deforestation over 3500 years ago to expand pastureland, lowering the timberline by about 300 meters. The timberline, marking the boundary between the subalpine and alpine elevation zones, is predominantly established by Arolla pine (Pinus cembra L.). The Arolla pine forest in Obergurgl, ranging from 1950 to 2100 meters above sea level, covers approximately 20 hectares and includes some trees that are over 300 years old. Not only are there Arolla pines, but there are also scattered dwarf shrubs waiting to be explored.

During this excursion, we will explore the Obergurgl Arolla Pine Forest, a National Monument since 1963, and discuss its unique alpine ecosystem. The hike will take us through Arolla pine forests and dwarf shrub heaths (for example, Calluna vulgaris, Vaccinium species), with breathtaking Alps views. We will also conduct field measurements and laboratory work to deepen our understanding of forest ecosystems and their dynamics.

The hike lasts about 3 hours, with short breaks, and covers steep, rocky terrain. Please wear hiking boots and bring warm clothing. This excursion offers an excellent opportunity to apply ecological concepts in the field and continue discussions on forest ecosystems in an alpine environment.
