What Can Forest Genetic Monitoring Tell Us? Key Takeaways from Our Recent Transnational Event

How can we tell when a forest population is beginning to lose the genetic diversity it needs to adapt?

This question formed part of the discussion during the recent DIVERSE_GENE_WATCH transnational online event, “Forest Genetic Monitoring in the Baltic Sea Region: Guidelines, Management Scenarios, and Pilot Insights on 11 September 2026”.

Genetic diversity is one of the foundations of a forest population’s ability to adapt. Forest Genetic Monitoring (FGM) can therefore help answer a practical conservation question: Are our efforts to conserve forest genetic resources actually working?

Conservation is not only about maintaining tree species where they currently occur. It is also about maintaining the genetic variation that allows populations to continue evolving and adapting through natural selection as environmental conditions change. Climate change, pests, diseases, competition and other pressures can alter which trees survive and reproduce. Monitoring genetic change across generations can help us understand whether populations still have sufficient adaptive capacity  and whether additional conservation or management measures may be necessary.

In this sense, Forest Genetic Monitoring can provide an early-warning system, helping forest managers and conservation authorities move from simply observing change towards deciding when and how to respond. For Forest Genetic Monitoring to work in the long term, it also needs an institutional home.

Across the Baltic Sea Region, DIVERSE_GENE_WATCH is exploring how a common monitoring approach could be connected to existing organisations responsible for forest genetic resources, conservation and forest management. Rather than creating an entirely separate system, the project builds on existing structures, monitoring sites and knowledge. This includes Gene Conservation Units documented through EUFGIS, as well as experience from existing genetic monitoring and forest genetic research initiatives.

Using established resources also helps make monitoring results more comparable across countries and contributes to a wider European perspective on forest genetic conservation.

An important part of the project is therefore not only developing scientifically sound methods, but also making them practical enough for long-term operational use. Sampling, storage and assessment methods need to be applicable not only by researchers but also, where possible, by practitioners and institutions responsible for monitoring forests.

DIVERSE_GENE_WATCH is now testing its proposed monitoring guidelines through pilot activities across the Baltic Sea Region. The lessons from these pilots will help refine the approach and support the development of a durable transnational Forest Genetic Monitoring network.
