Long-term environmental research at Zöbelboden
Environment Minister Norbert Totschnig visited the Zöbelboden research station in Kalkalpen National Park Upper Austria and got a firsthand look at the current scientific projects there.
Environment Minister Norbert Totschnig: “The Zöbelboden research site provides valuable data and information for understanding the interaction between climate change and biodiversity and for making our forests more resilient. At the same time, this specialized monitoring network clearly shows us that our consistent air quality policy is working and that pollutant levels in ecosystems are measurably declining. It is important to me to protect our environment and ecosystems in a sustainable way, using scientific facts as our guide. To that end, Zöbelboden will continue to be a particularly valuable source of data in the years to come.”

650 high-tech devices and sensors
The Zöbelboden measuring station is one of the largest and best-equipped monitoring and research sites in Austria. The Federal Environment Agency has been conducting continuous environmental monitoring there for nearly 35 years, primarily on behalf of the Ministry of the Environment and in partnership with Kalkalpen National Park the Austrian Federal Forestry Office. Here, unique data series are generated on the effects of global environmental changes on Alpine mountain forests. The focus is on the consequences of climate change, the dynamics of the carbon and nitrogen cycles, the preservation of biodiversity, and the improvement of air quality.
Using 650 networked high-tech devices, hundreds of parameters—such as air pollutant concentrations, soil temperature and moisture, and tree growth—are recorded in real time. In addition, rainwater and spring water, soil, rock, leaves, and litter are examined in greater detail. Chemical analyses provide precise data on nitrogen and sulfur, phosphorus and carbon, and even heavy metals. This allows important relationships to be examined, such as which pollutants the forest absorbs and what proportions are released back into the water.
Impacts of Climate Change
Forests play a significant role in climate protection, but are becoming increasingly vulnerable to extreme events such as droughts, storms, and pest infestations. The current TreeNet-ATproject, in collaboration with the Federal Research Centre for Forestry, the University of Innsbruck, and the University of Natural Resources and Life Sciences, Vienna, is establishing an innovative real-time monitoring system for the comprehensive tracking of drought stress in trees and their response to climate change, with the Zöbelboden serving as a key data source.
Cold-loving plants are declining particularly rapidly in the Alps
The significance of the measurement data from Zöbelboden is also evident in a globally acclaimed study published in the spring of 2026 in the renowned scientific journal Nature. An international consortium, including the Federal Environment Agency, analyzed changes in European plant communities under the influence of global warming. Heat-loving species are spreading rapidly, while cold-tolerant species are gradually being pushed back. The results show clear differences between habitats: Alpine summit regions exhibit the most significant changes. Alpine plants adapted to extreme cold are particularly at risk, including the glacier buttercup in the Central Alps and the northeastern Alpine primrose in the Northern Limestone Alps. In contrast, drought-resistant, heat-loving species such as the mountain houseleek or various thyme species stand to benefit.
Plants in deciduous forests are moving westward
It is a well-known phenomenon that plants and animals are migrating northward and to higher elevations due to global warming. Plants in European deciduous forests, such as grasses, herbs, and ferns, are an exception.
A study published in the journal Science analyzed long-term data from around 3,000 deciduous forests across Europe, including vegetation data from the Zöbelboden. The analysis confirms that plants in European deciduous forests have shifted significantly westward in recent decades. The research identified the uneven distribution of nitrogen inputs across Europe as the primary cause. Many nitrogen-loving, widespread species are displacing rare species, with negative consequences for biodiversity. In the beech forests of the Kalkalpen National Park, for example, this has led to sticky sage displacing the common globeflower.
A Hotspot for Long-Term Data in Europe
Today, 18 international monitoring systems and research networks already make use of the station’s state-of-the-art infrastructure and historical data sets. Zöbelboden is considered one of Europe’s rare “hotspots” for long-term data spanning all compartments of an ecosystem.
