Stadler supported the planting of 1,000 climate resilient trees across the UK in 2024-25
Stadler is proud to be working in partnership with GreenTheUK and the Royal Forestry Society (RFS) to plant climate-resilient trees across the UK’s woodlands. This collaborative initiative brings together the RFS’ 140+ years of forestry expertise and GreenTheUK’s community-driven approach to ensure every tree planted contributes to a wider, lasting environmental legacy.
The RFS is a leader in sustainable woodland management. With deep-rooted knowledge passed down through generations, they understand that healthy, thriving woodlands depend not only on the trees we plant, but how we care for them. Our woodlands are managed with both climate and biodiversity in mind.
This partnership is helping to strengthen the resilience of UK woodlands against pests, diseases, and the accelerating impacts of climate change. Increasingly frequent extreme weather events including floods, droughts and storms are placing additional stress on trees. Weaker trees are far more vulnerable to disease and pests. By planting a broader mix of tree species, including some non-native and naturalised varieties, we improve the overall health and adaptability of woodland ecosystems, giving them a better chance of survival in the face of climate change.

While native species are brilliant for biodiversity, we simply don’t have enough of them to ensure resilient sustainable woods and trees for the future. Many of our native tree species are under threat from new and existing pests and diseases. That’s why diversifying our woodlands is key. If we plant a wide variety of tree species (both native and non-native) we will help to ensure that at least some species will survive future threats. Tree cover habitats will be maintained and our native wildlife will have new and existing trees that they can depend on. Encouragingly, species like red squirrels have already adapted to living in some non-native conifer woodlands because of the ample food supply their cones provide. According to the Forestry Statistics 2024, woodland cover in the UK now stands at 13.5%, with 20,660 hectares of new woodland created in 2023/24, a positive step toward the government’s target of 30,000 hectares annually. With support from businesses like Stadler, we can help ensure that number continues to grow each year.
Expanding woodland cover plays a vital role in tackling climate change. Woodlands store an estimated 4,000 million tonnes of carbon in the UK alone, according to the Save Our Wild Isles campaign. Beyond carbon capture, trees help stabilise soils with their extensive root systems, reduce flood risk by intercepting rainfall with their canopies, and improve water retention in the ground. Some trees can even signal distress through chemical messaging when under attack, giving nearby trees a chance to defend themselves, a remarkable form of natural resilience.
Yet despite all this, the UK remains the second-largest importer of wood products in the world, much of it for use as biofuel. Relying on imports not only undermines our green credentials, but also increases the risk of introducing new pests and diseases to our woodlands.
That’s why responsible, UK-based tree planting guided by expert partners, like the Royal Forestry Society and GreenTheUK, is so important. It’s about planting the right trees, in the right places, and caring for them in the right way so our woodlands can thrive for generations to come.
Tree Species Planted:
250 trees planted in North Yorkshire
In this valley woodland, non-native conifers are being replaced with native trees, specifically chosen for their wildlife value. The new woodland will create a ‘wildlife corridor’ along the edge of a beck, providing food and shelter for birds, mammals and insects. By increasing the number of different trees in this woodland, it will create space for different plants (including local woodland wildflowers) and animals, which will increase biodiversity in the valley.
250 trees planted in Cumbria
Restoring this ancient woodland, this project aims to transition this woodland from a composition of 70% conifer to 70% broadleaf and to move to a Continuous Cover Forestry (CCF) plan. CCF is a strategy that increases the diversity and resilience of a woodland by always having a spread of different aged trees and different species and providing a variety of habitats for local birds and other wildlife at all times. With red squirrels in the area, the tree species have been selected specifically with them in mind, as well as flowering species to attract insects, species that produce nuts and seeds and that provide cover for nesting birds.
250 trees planted in Merseyside
This project demonstrates multi-purpose forestry, managing it for both wildlife and timber production. A felled pine plantation covered with a dense layer of bracken, this project aims to restore the pine woodland and introduce a mix of broadleaf trees and shrub species to create graded edges and understory layer. Having a diverse structure within a woodland offers a wider range of habitats for wildlife and makes the woodland more resilient to pests and disease.
250 trees planted in Cumbria
This very old woodland experienced storm damage from Storm Arwen back in 2021 and had to be clear-felled which was a difficult task. This project aims to create an appropriate species mix that fits the landscape and develops a biodiverse long term forest stand. The area is managed for red squirrels and red kites and species have been chosen with this in mind to provide food and habitat. Along with the bluebells in the spring, this woodland will enhance the visual impact of the landscape which is enjoyed by local residents and people travelling past on the busy A road.
