Article
Soil function assessment (SFA) plays an important role in evaluating the impact of management practices, land‐use changes and construction work. The Soil Evaluation for Planning Procedures (SEPP) tool is one of the few existing SFA tools that allow automated SFA. It was originally developed to address land‐use planning issues, which traditionally p...

High mountain areas are exceptionally heterogeneous. Therefore, to estimate soil characteristics, various influencing factors have to be considered. We investigated soils in Martell Valley (IT) that developed under optimal conditions along a chronosequence (0-200 yrs), as well as more mature soils (12000 yrs) with various dynamics (e.g. snowbeds, s...
Presentation
The popularity of alpine skiing is still increasing in the Alps. Consequently, the demand for bigger ski resorts and for broad and levelled ski slopes is rising, too. The reconstruction of entire slopes has become normality in many regions. As a result, the soil structure is strongly influenced and new vegetation needs to be sown often followed by...

Article
Shallow erosion is caused by processes such as landsliding, snow gliding, avalanches, animal trampling, or human activities and frequently occurs on high mountain grasslands. It can lead to significant long-term losses of grassland and related ecosystem services, e.g. fodder production, or water retention. Since restoration of subalpine and alpine...

The modelling of forest ecosystems is a broad scientific field, encompassing species distribution, dynamic forest succession, growth and disturbance, and biogeochemical cycles. Soil information is frequently required for a holistic and spatially explicit modelling approach. Information on soil properties at sufficient resolution to be incorporated...
Article
High mountainous areas are geomorphologically active environments which are strongly shaped by redistribution of sediments and soils. With the projected climate warming in the 21st century and the continued retreat of glaciers, the area of newly exposed, highly erodible sediments and soils will increase. This presents a need to better understand an...

Parent material is an important factor of soil formation and consequently plays a dominant role in both traditional field soil survey and digital soil mapping. The emergence of a new generation of detailed geological maps at high spatial resolution in South Tyrol raises the question of how to effectively incorporate these into soil mapping efforts....
Article
Soil chronosequences in Alpine areas have often been applied to trace physical, mineralogical and chemical soil properties over time. How the soil pore system of undisturbed soils evolves, however, has not yet been clarified. We therefore investigated two soil chronosequences in the Swiss Alps spanning a time period from a few decades up to the Ear...
