The Research Unit Forest Resources and Management monitors and analyses change in the landscape and in the forest. The research Group Stand Dynamics and Silviculture, which focuses on tree- and stand-level ecosystem processes and how they can be influenced by man, is offering a position as a

starting in Spring 2025 for the duration of two years (with the option for an extension). This PostDoc project is funded by the Swiss National Science Foundation (SNSF). It is based on a unique network of research plots in Switzerland, Chile and Germany. In stands of pure native broadleaved species (European beech in Europe and Nothofagus in Chile), pure non-native Douglas-fir and mixtures of both, multiple plot triplets are replicated per country. The goal of the research project is to study the response of tree and stand growth and vitality to mixing of native and non-native species and interactions with stand structural complexity. For this study, classic methods of forest growth research will be related to structural data generated by 3D laser scanning (mobile laser scanning, MLS). We strive to identify structural drivers of mixing effects on tree growth and mortality that can be generalized across hemispheres.

A second subproject that investigates effects of mixing native and non-native tree species on ground vegetation diversity and the invasive potential of Douglas-fir is based at the University of Applied Forest Sciences Rottenburg, Germany. You will closely work together with collaborators in Switzerland, Chile and Germany. Your task is to coordinate and conduct joint field trips in all three countries. You will estimate tree growth and vitality by analysis of increment cores and assessment of the 3D canopy structure. You can count on the support of a dedicated field technician as well as of enthusiastic project partners from different groups at WSL and at the partner institutes in Germany and Chile managing the respective trials, allowing you to benefit from multiple perspectives and expertise. You will publish the results in international scientific journals and present them at dedicated conferences.

You recently acquired a PhD degree with a solid expert knowledge in tree growth and stand dynamics research or in a related field. A strong background in statistics and experience in organizing and conducting scientific field campaigns are essential. You bring experience in collaboration in international and interdisciplinary research projects. You have excellent written and oral communication skills in English, Spanish skills are desirable. A high standard of independent, structured and careful working attitude, as well as a driving license are indispensable. The position is based at the Swiss Federal Research Institute WSL headquarters close to Zurich, but the project foresees stays in Germany and Chile of several months.
