The unit maintains a high level of expertise in experimental design, field trial layout, sampling and measurement methods, as well as in analysis and computational methods for field-related data.

Long-term field experiments: the cornerstone of our operations

The Unit for Field-based Forest Research is responsible for managing the faculty’s approximately 1,800 long-term forest field experiments. These trials cover a wide range of disciplines and research questions and represent a vital source of knowledge for both national and international research.

Since 1990, around one-fifth of all international publications from SLU’s Faculty of Forest Sciences have been based on data from these long-term field experiments. They also play a key role in undergraduate and postgraduate education, professional training, and excursions.

Information about the forest field trials is collected in several databases, including Silvaboreal – a Swedish registry database developed and managed by the Unit for Field-based Forest Research. Silvaboreal contains information on approximately 4,000 trials from various actors and is an important resource for research and planning.
