Peli BioThermal supported the planting of 1,000 climate resilient trees across the UK in 2025-26
Peli BioThermal is working in partnership with GreenTheUK and the Royal Forestry Society (RFS) to grow more resilient and sustainable woodlands across the United Kingdom. This work supports a long-term approach to building healthier woodlands that can adapt, thrive and continue to deliver for both people and nature.
Trees and woodlands play a vital role in tackling climate change and reversing biodiversity loss, while also bringing wider benefits to communities and the economy. Across the UK, many woods face increasing pressure from environmental change, pests, disease and under-management. Without the right care, these challenges can limit the ability of woodlands to recover and grow stronger over time.
By supporting projects that prioritise the right tree in the right place, and encouraging active, ongoing management, Peli BioThermal is helping to ensure new and existing woodlands are more resilient, productive and diverse. This includes planting a thoughtful mix of species to strengthen ecological balance, improve adaptability and maintain habitats for wildlife now and in the future.
Increasing tree cover is only part of the solution. Bringing more woodlands into active management is equally important, helping to improve woodland condition, boost biodiversity and unlock long-term environmental value. Well-managed woods are better equipped to cope with changing conditions, from extreme weather to emerging pests and diseases, while continuing to provide essential ecosystem services.
Expanding and improving woodland cover helps capture and store carbon, supports nature recovery, improves soil and water health, and contributes to a more sustainable domestic timber resource. Growing more home-grown timber is increasingly important for the UK, helping to reduce reliance on imports, which currently supply around 80% of timber demand. A stronger domestic timber resource can lower the carbon footprint associated with imported materials, while also reducing the risk of introducing new pests and diseases through international trade.
Through its support, Peli BioThermal is contributing to a bigger, shared ambition: a future where resilient, well-managed woodlands are at the heart of the UK’s natural environment. By investing in the long-term health of our woodlands, this partnership helps ensure that the benefits of trees are felt for future generations.
Tree Species Planted:
500 trees planted in Northumberland
This larch and sitka compartment was clear felled, due to susceptibility to Phytophthora ramorum – a disease that kills larch trees. This compartment is being replanted with a wider variety of both conifer and broadleaf trees with the aims of continuing to grow sustainable timber, which supplies the local saw mills, and creating a more diverse habitat for the local wildlife. The tree species that have been selected have been chosen for their suitability to grow on this site and potential to develop into a resilient woodland through current low risks to any threats of pests and diseases.
500 trees planted in County Durham
Moving from a single species that is at risk of disease, this site is replanting with a diverse mix for timber production, biodiversity and red squirrel support. The conifer crops will support the local sawmills and broadleaves will provide more diverse habitats for the wildlife and provide shelter for adjacent agricultural fields. The conifers are also a great food source for the red squirrel population which are in this area and they provide extra habitat and their edible cones all year round.
