Forest Research, Great Britain’s leading forestry research agency, has been commissioned by Welsh Government to develop a list of tree species which will help strengthen the resilience, productivity and long-term sustainability of Welsh woodlands. Woodknowledge Wales, Bangor University and Edinburgh Napier University will work with Forest Research to develop the shortlist to identify a shortlist of productive tree species, suited to both current and predicted future climatic conditions in Wales.

The need for such a shortlist has been highlighted by the Welsh Government’s “Making wood work for Wales” timber industrial strategy, and similar programmes across the UK. Scotland recently completed its own shortlisting project, funded by Scottish Forestry, and parallel work is now underway in England, funded by Defra.

The Welsh project will run alongside the work in England, creating significant opportunities for collaboration, alignment and shared learning across the three nations in areas such as tree breeding, plant and seed supply, and silvicultural research. A key focus of the work in Wales will be on research into wood properties and market development.

The purpose of the shortlists is to support strategic decision-making across the sector. The shortlists are not intended to order particular species choices at the operational or site level, where land managers will continue to consider local conditions, objectives, and preferences in line with the UK Forestry Standard and other guidance.

Tree species prioritisation touches the core of business models, commercial strategies, professional and cultural beliefs. Making a shortlist of tree species for Wales will be a team effort. People from all parts of the forestry sector will be invited to explore ideas and opportunities for growing, processing, and using home-grown timber in the future with the goal of building a strong and resilient forest industry.

Species on the Welsh shortlist will be those considered suitable for deployment now, while an additional reserve list will identify promising species that require further research before operational use.

Efforts will be coordinated at a UK level by the UK Forest Genetic Resources (UKFGR) Group, ensuring coherence, consistency, and a joined-up approach to species diversification.

John Healey, Professor of Forest Sciences at Bangor University commented, “Bangor University is delighted to be contributing to the new Welsh tree species shortlisting project. This will enable the project to capitalise on Bangor's recent strengthening of the link between its UK-leading expertise in wood science, its research excellence in forest resilience, and its close collaboration with the forestry and wood industries. This has contributed to our ranking in first place in the Times 2026 University league table for Agriculture and Forestry. We look forward to this new project further developing our good track record of collaboration with the Forest Research agency and with Woodknowledge Wales, to ensure that the Wales project benefits from a strong input from Welsh institutional expertise and is informed by a substantial engagement from across the Welsh forestry and wood industry sectors."

Dr Morwenna Spear, from the BioComposites Centre at Bangor University, said “We are very excited to be involved in this project. The question of which tree species will be more widely planted, and their potential in the many wood-using industries in Wales and beyond, is an essential one to wrestle with. We have an extensive knowledgebase on different wood products at the BioComposites Centre – having worked with types of engineered wood such as medium-density fibreboard (MDF) and particleboard, plus paper and pulp moulded packaging, as well as solid wood, innovative treatments and mass timber for structures. Each application has unique processes and desired properties for the timber it uses – adaptability and innovation are key to a resilient forest products sector for the future.”

David Edwards, lead researcher on the project at Forest Research said, “The forestry sector has long relied on a narrow range of productive tree species. As climate change accelerates and threats from pests and diseases continue to rise, the need to diversify tree species in Wales has become increasingly urgent. Developing agreed regionally focused shortlists of suitable species, in collaboration with experts and stakeholders across the forestry sector, will help strengthen the resilience, productivity, and long-term sustainability of Welsh and UK woodlands. Collectively, the initiatives across Wales, England, and Scotland represent one of the most comprehensive and coordinated evidence gathering exercises ever undertaken for commercial tree species selection in the UK. This will support and inform forestry diversification programmes and will deliver an evidence-based, nationally aligned foundation that the entire forestry sector can build upon.”

Deputy First Minister Huw Irranca-Davies said, “Forests need to be healthy and resilient if they are to maintain and enhance their capability to produce timber, provide high-quality habitats for wildlife and continue to deliver for society.  We need to future-proof our forests, suitably adapting to climate change, introducing greater diversity and appropriate species mixes for future resilience.  The launch of this project is an important step to enable forward planning, vital given the relatively long-term cycles involved in ensuring Wales has access to genetically diverse and climate-appropriate stock to plant sustainable forests for future generations.”

Gary Newman, CEO Woodknowledge Wales, commented, “We are delighted to be working closely with Forest Research, scientists at Bangor University and Edinburgh Napier University and a wide range of industry stakeholders in Wales to ensure we can make best use of a wider range of tree species. We consider this project as an enabler for future collaboration focused upon increasing resilience in the forest and within its associated value chains.”
