Woodland habitat that will help combat climate change and reduce flood risk has been created in Devon and Cornwall by South West Water (SWW).

Trees also play a vital role in enhancing river water quality, by acting as natural filters, reducing pesticide run-off into watercourses, preventing soil erosion, and slowing water flow. By planting trees SWW says it is also helping to combat climate change, reduce the risk of flooding, and providing homes and food for wildlife.

The UK water company set out to plant 300,000 trees by 2025 – which it has now greatly exceeded after planting 390,000. Many of the trees planted have been delivered by the utility’s Upstream Thinking programme.

The project’s focus is on a proactive approach to water management which not only ensures the provision of clean water, but also promotes resilient and thriving ecosystems for future generations. A key partner is Devon Wildlife Trust, which has provided 45,729 trees – including species like blackthorn, hazel and oak.

These have been planted on behalf of farms and landowners across the region to help prevent run-off and improve natural water quality.

David Smith, natural resources team manager at SWW, said, “Trees are amazing as they act like natural filters and prevent flooding by absorbing water. Our tree planting efforts help ensure slower and cleaner flows into rivers and our Upstream Thinking programme is proud to work with other partners in all the catchments we operate in.”

Emma Richardson, director of nature based solutions at Devon Wildlife Trust, said, “We are so pleased to be delivery partners on South West Water’s Upstream Thinking programme and for their support in delivering this important project to improve water quality and resilient water resources, along with the environmental benefits this brings for wildlife and people. We work closely with the Woodland Trust to be able to plant trees across our river catchments to make our rivers and streams healthier and climate resilient."

South West Water has now committed to planting a further 300,000 trees from 2025-2030.

The Upstream Thinking project delivery partners include Cornwall Wildlife Trust, Devon Wildlife Trust, Westcountry Rivers Trust, and the Farming and Wildlife Advisory Group.
