genetskog

Genetskog is a term used in forestry and conservation to describe a system or area focused on conserving and utilizing the genetic resources of tree species. The concept emphasizes maintaining genetic diversity within and among populations so that forests can adapt to changing environmental conditions, pests, and diseases, while supporting sustainable production.

A genetskog typically includes in situ conservation in natural or semi-natural stands, where evolutionary processes can continue and local adaptations are preserved. It also involves ex situ elements such as seed orchards, clone banks, and seed banks that provide material for breeding, research, and reforestation. Provisions for provenance and progeny testing, as well as monitoring of genetic diversity indicators, are common components to track changes over time.

Management aims to balance conservation with practical needs, ensuring a broad genetic base is available for planting stock and breeding programs. This often entails selecting diverse seed sources, establishing provenance trials to identify climate-appropriate genotypes, and protecting old or unique stands that harbor rare alleles. Collaboration among foresters, geneticists, and policymakers is typical, with guidelines that promote genetic resilience alongside timber production.

Genetskog intersects with forest genetics, biodiversity conservation, and sustainable forest management. Policy frameworks may require consideration of genetic diversity in seed sourcing, reforestation, and restoration projects. Challenges include adapting to rapid climate shifts, managing gene flow between stands, and maintaining robust genetic data to inform decision-making.
