Powys, a county in central Wales, is highlighted as a leading example of how nature-based solutions, specifically tree planting, can effectively address the growing challenges of flood management. Facing increased flood frequency and intensity due to rising rainfall, climate change, and development, Powys has strategically planted hundreds of trees across the region alongside traditional flood control methods. This initiative aims to protect communities, reduce flood risks, and simultaneously enhance biodiversity.
Trees and woodlands offer significant benefits in mitigating flood risks. Their ability to absorb and slow down rainwater reduces surface runoff, a major contributor to flooding. Furthermore, tree roots stabilise soil, preventing erosion and sedimentation in rivers. In Powys, tree planting initiatives have focused on key areas like floodplains and riverbanks, where the new woodlands act as natural buffers, absorbing excess water during heavy rainfall and releasing it gradually, offering a sustainable alternative to man-made defences.

The success of Powys' tree planting efforts is attributed to strong collaboration among local authorities, conservation groups, landowners, and environmental organisations such as Natural Resources Wales, Powys County Council, and the Woodland Trust. A key project involves planting native broadleaf trees along the catchments of the flood-prone Rivers Wye and Severn. The focus on native species like oak, ash, and birch ensures benefits for both flood management and local biodiversity, creating habitats and improving ecosystem resilience. These projects also align with broader environmental goals like carbon sequestration and soil health restoration.
While the full impact of tree planting will take time due to the growth period of trees, the long-term benefits extend beyond flood management, including climate change mitigation, improved air and water quality, and enhanced natural beauty. Local residents have actively participated in planting and tree care, fostering environmental stewardship. Building on its success, Powys aims to expand its tree planting efforts, creating more green spaces for flood mitigation and public recreation, with the potential to serve as a blueprint for other flood-prone regions seeking sustainable solutions. This work highlights how Powys’ experience demonstrates the value of working with nature, positioning trees as vital tools in the battle against flooding and a key to a safer, greener, and more resilient future.
