The Swiss Federal Institute for Forest, Snow and Landscape Research WSL is part of the ETH Domain. Approximately 600 people work on the sustainable use and protection of the environment and on the handling of natural hazards.
The Forest and Soil Ecology research unit investigates the functioning of forests and soils, as well as the influence of environmental factors on above- and below-ground processes in forest ecosystems. Within the framework of the Long-term Forest Ecosystem Research (LWF), the leaf area index is regularly assessed on monitoring plots using light measurements and hemispherical photography. For this fieldwork and the subsequent analysis of the data collected, we offer a position from July 2026 to approximately mid-August 2026 for a duration of 1.5 months
Internship Long-term Forest Ecosystem Research (LWF) (f/m/d)
You conduct light measurements using a LI-COR device as well as hemispherical photography in the field. Fieldwork is weather-dependent and often takes place at short notice, as well as during the day’s margin (shortly before or after sunset). You move safely and efficiently across sometimes uneven terrain and, whenever possible, especially on challenging sites, work in pairs. The role also includes preparation of fieldwork (in particular organizing equipment) as well as post-processing and analysis of the data collected.
Work instructions are available in German, French, and English. The measurement points on the LWF plots correspond to the vegetation plots where vegetation surveys will be conducted this summer. With good botanical knowledge, there is also the opportunity to assist with the vegetation surveys. Further information on the
LWF program, as well as on
LAI and hemispherical measurements and
vegetation surveys can be found on the linked websites.
You have recently completed a bachelor’s or master’s degree in environmental sciences or a related field, or you are currently still studying. You are highly flexible and willing to carry out short-notice assignments under suitable weather conditions. In addition, you have good physical fitness and are sure-footed in rough terrain, with an interest in fieldwork and data analysis. You work carefully and reliably, are flexible with your time, and are also willing to stay overnight away from home if required. Good knowledge of at least two of the following languages (German, French and English) is an advantage; a valid driving licence is a plus.
