Berthold Traub is a system specialist in the group Scientific Services NFI at the Swiss Federal Institute of Snow and Landscape Research WSL. He did a diploma in forestry at the University of Freiburg i. Br., where he also completed a Ph D. He began his career as a researcher working in the Swiss NFI program at WSL with a focus on statistical inventory methods, international reporting and the analysis of inventory data. While working in the private sector, he gained further experience in managing large data analysis applications and software validation in a regulated environment. In his current role, he is responsible for managing and maintaining the integrated data-analysis applications of the Swiss NFI, as well as for coordinating regional forest inventories in Switzerland. His research focus is on data quality, particularly on the reproducibility of data collected from field samples.

Christoph Fischer is a forestry scientist. His background is in forestry and forest ecology, as well as tropical and international forestry. He received his doctorate from Georg-August-Universität Göttingen, Germany, where he gained in-depth experience in techniques for conducting forest inventories and in remote sensing. He also planned, led and evaluated the first, sample-based forest inventory of Burkina Faso. Since 2011, he has carried out research for the Swiss National Forest Inventory (NFI) on resource availability and forest recreation.  He actively participates in international projects on the harmonisation of wood resource assessments using NFI data. He is author and co-author of various scientific articles and book chapters. Since 2018, he has been head of the Swiss NFI’s module on protective forests.
