Context

However, as we move towards ambitious afforestation goals, there is a major knowledge gap around the resulting genetic diversity in planted versus naturally colonised woodlands and how this will influence resilience to environmental change, pests, and diseases.

Research aims and objectives

Aim

By working closely with industry stakeholders, who contribute substantially to current afforestation activity we will contribute to development of best practice, aiming to deliver resilient woodland expansion in the UK.

Objectives

This project will assess the differences in genetic diversity in planted versus naturally colonised woodlands, and particularly where climatic, ecological or management drivers result in genetic bottlenecks to young tree populations. It will:

• Compare the tree health and genetic diversity in planted and naturally colonised young woodlands, focusing on oak (Quercus) and birch (Betula).
• Characterise potential genetic bottlenecks and selection in planted and natural afforestation pipelines.
• Draw up actionable recommendations for optimising afforestation activities to help deliver genetically diverse and resilient tree populations.

Expected outcomes

• The project will provide recommendations on best practice improvements to current tree planting and natural colonisation protocols, including any recommendations to improve current seed sourcing guidelines, record-keeping and propagation.
• The project will also provide a peer review publication and popular press outputs to communicate findings to a range of audiences.
