Sebastian Peters is conducting basic research into climate change. Over the course of this summer, the forest scientist is investigating 1000 hectares of forest in the district - an area equivalent to around 1400 soccer pitches. Peters works at the Baden-Württemberg Forest Research Institute (FVA) and is interested in what lies beneath the ground. Using soil samples, he will analyze the growing conditions for trees and create valuable basic data for the right choice of tree species.
The changing climate conditions can already be seen in the forest. The prolonged drought has left its mark on the forest trees and is increasingly affecting them. Foresters in the district are therefore asking themselves which tree species will be best able to cope with future conditions. "In addition to existing specialist knowledge and experience, a lot of research work is still needed to make the forests of tomorrow fit and stable," says Dr. Michael Nill, head of the forestry department at the district office.
The literally fundamental decision-making basis for such considerations is the soil on and in which a tree grows. "How deep can the roots go? How long can rain be stored? Are there enough nutrients?" Sebastian Peters is currently working on all of these questions. The so-called site mapping is available for most areas in the district, but is still incomplete or outdated in some places.
Particularly in the private and municipal forests of Eberdingen, Hemmingen, Markgröningen, Oberriexingen, Sersheim and Vaihingen/Enz, Peters will now take and evaluate a drill sample every 50 meters. The data collected on soil type, surrounding plants, terrain and water balance will be digitally recorded directly in the forest. Taking the soil samples is a physically demanding task in which municipal forestry workers and employees are actively supporting Peters.
Following the field work, the data collected is compiled into new map overviews at the FVA in Freiburg. On this basis, the foresters on site can decide which tree species are suitable for which area. Peters is looking forward to the time ahead of him in the district: "Site mapping allows you to get to know an area from a completely different perspective."

From the interplay of bedrock, climate, soil characteristics, location in the terrain and vegetation, site mapping can provide recommendations as to which tree species can grow on a site.
