Satellite model finds Alpine peatlands may be smaller than official maps show
Peatlands in the Alps are mostly small, scattered and difficult to access. As a result, up-to-date information on their extent and condition is often lacking. An international research team, including researchers from the University of Göttingen, has now developed a cross-border approach to identifying these particular areas. A comparison with official maps shows that the model identifies many…
Alpine peatlands in Austria, Germany, and Switzerland may be smaller than previously thought, according to a new satellite model developed by an international research team. The model, which combines data from visible light and radar satellite sensors collected between 2019 and 2023, paired with on-the-ground studies, found that many peatlands were significantly smaller than those mapped by official records.
Aerial photos revealed disturbances at nearly 90% of the sites, including encroaching vegetation, new infrastructure, and drainage ditches for agricultural use like hay production. The team, including researchers from the University of Göttingen and Mendel University in the Czech Republic, discovered that these disturbances likely caused the peatlands to be smaller in reality.
Alpine peatlands are important for carbon storage, water regulation, and habitat for specialized species. The researchers urge for more comprehensive surveys and better protection and restoration planning, emphasizing the need for regular monitoring and updated maps. Their model can facilitate these efforts by enabling satellite monitoring and targeted field surveys.
