Diversity of forests forms the interconnected fabric of life that supports their functions. The fabric of life enables the functioning of forest ecosystems, resilience to disturbances, adaptation to environmental changes and sustainable timber production. Trees make the forest yet they cannot live without the symbiosis with fungi, soil microbes recycle nutrients from dead plant materials back to the trees and predators control the overgrowth of herbivore populations.

Are all nodes in the fabric of life equally important? How much the fabric of life may be disturbed before it cannot support the life of a forest? Can people repair the fabric of life by means of nature management? How can we measure these phenomena? What is the value of the forest diversity for the nature, economy and society? We discussed these and many other questions in the Forest Sciences’ Day organised by the Finnish Society of Forest Science on 26 October 2022.

In the morning, we had a plenary session, in which the best Finnish scientists of biological diversity spoke about measuring and valuating of the diversity from ecological, economic, societal and methodological viewpoint. We also heard a review of the EU biodiversity strategy, aim of which is to stop the nature loss and restore biological diversity.

The science clubs of the Finnish Society of Forest organised six parallel sessions in the afternoon. In these sessions, the forest diversity, its measurement and valuation was discussed from the viewpoints of several subdisciplines of forest sciences. Parallel session programmes can be found below on this page.

Forest Sciences’ Day was organised for the 30th time. The first Forest Sciences’ Day was organised in connection to the 75th anniversary of the Finnish Society of Forest Science. Since 1995, the Day was organised annually under the name Forest Science Day. We recovered the name in plural, Forest Sciences’ Day, now on the occasion of the 30th event for emphasising the multidisciplinary nature of forest sciences. Multidisciplinary science is needed in the measuring and valuation of the fabric of life.

All talks were recorded, unless the speaker had justified reasons to deny recording. The name of the talk is the link to the recording. The parallel session recordings are found on the page of the session.
