Participatory mapping of the forest community stakeholders in Europe focusing on forest genetic resources, forest reproductive material, and protected forests

Abstract: The genetic diversity of forest trees, as provided by Forest Genetic Resources (FGR) and being the basis for the production of Forest Reproductive Material (FRM), is fundamental for maintaining forest resilience, adaptability, health, productivity, and biological diversity. Despite their importance, stakeholder governance of genetic diversity remains under-studied. This study aims to address this gap by mapping the forest stakeholder landscape FGR governance. Using the Quadruple Helix Approach, we categorised stakeholders into academia, industry, government, and civil society identifying relevant sub-communities. The mapping process involved iterative revisions through expert consultations, workshops, and literature scoping. Results show that the FGR sub-community is situated between strict conservation efforts and applied forestry, supporting both genetic conservation and productive forest management. The FRM sub-community, dealing specifically with the production and deployment of FRM, prioritises tree breeding, seed production, and afforestation/reforestation programmes. Meanwhile, the Protected Forests (PF) sub-community focuses on strict nature conservation, advocating minimal human intervention while facing pressures from resource extraction, tourism, and land-use conflicts. The diverging attitudes and values of close-to-nature forest management, intensive forestry, and strict protections, respectively, exist within same stakeholder groups, as well as among different ones, and are spanning all sub-communities. The study uncovers key tensions such as competing land-use priorities between forestry, agriculture, infrastructure and energy sectors, limited flow of knowledge between stakeholder categories and governance misalignments between local, national, and international regulations. The findings are particularly relevant for policymakers, forest managers, forest nurseries, conservation organisations, and industry stakeholders to balance conservation with sustainable forest utilisation. By integrating stakeholder perspectives and highlighting key governance challenges, this study shows where a common ground can be found and where divergent opinions are strong, opening the way for more integrated strategies and policies

Vendramin, Marjana Westergren, 2023, complete scientific database of research data

Abstract: This dataset contains the gene sequence variation data (vcf files and their tbi index files) of seven forest tree species used in the manuscript "Synchronous effective population size changes and genetic stability of forest trees through glacial cycles". For each species, between 411 and 651 genotyped trees are included, sampled across Europe in at least 20 locations. Several versions are provided. Species included: Pinus sylvestris, Picea abies, Fagus sylvatica, Populus nigra, Quercus petraea, Pinus pinaster, Betula pendula
Keywords: gene sequence, variation data, data set

Genomics and adaptation in forest ecosystems
Charalambos Neophytou, Katrin Heer, Pascal Miles, Martina Peter, Tanja Pyhäjärvi, Marjana Westergren, Christian Rellstab, Felix Gugerli, 2022, original scientific article

Abstract: Rapid human-induced environmental changes like climate warming represent a challenge for forest ecosystems. Due to their biological complexity and the long generation time of their keystone tree species, genetic adaptation in these ecosystems might not be fast enough to keep track with conditions changing at such a fast pace. The study of adaptation to environmental change and its genetic mechanisms is therefore key for ensuring a sustainable support and management of forests. The 4-day conference of the European Research Group EvolTree (https://www.evoltree.eu) on the topic of “Genomics and Adaptation in Forest Ecosystems” brought together over 130 scientists to present and discuss the latest developments and findings in forest evolutionary research. Genomic studies in forest trees have long been hampered by the lack of high-quality genomics resources and affordable genotyping methods. This has dramatically changed in the last few years; the conference impressively showed how such tools are now being applied to study past demography, adaptation and interactions with associated organisms. Moreover, genomic studies are now finally also entering the world of conservation and forest management, for example by measuring the value or cost of interspecific hybridization and introgression, assessing the vulnerability of species and populations to future change, or accurately delineating evolutionary significant units. The newly launched conference series of EvolTree will hopefully play a key role in the exchange and synthesis of such important investigations.
