Project summary

Edit project overview to modify the project summary.


Hills to Levels is an holistic catchment management approach across catchments in Somerset, aiming to ‘slow the flow’ to reduce flood risk, reduce erosion, improve water quality, deliver wider environmental benefits and increase resilience on the floodplain. The idea is that a lot of small-scale interventions will have an effect at the large catchment scale with the motto that ‘every field, every farm, every stream has its part to play in flooding and water quality’. The Hills to Levels approach started as a partnership between the RSPB, Royal Bath & West Society, Somerset Wildlife Trust and FWAG SW after the 2013/14 flooding of the Somerset Levels. The project aimed to reduce flood risk, increase farm resilience and to join up the communities in the upper and lower catchments in Somerset.
