Project summary

Edit project overview to modify the project summary.


Sussex Flow Initiative is an innovative partnership project between the Sussex Wildlife Trust, the Environment Agency and the Woodland Trust, based in the River Ouse catchment in East Sussex. The project aims to promote and deliver Natural Flood Management (NFM) approaches helping to create a landscape that is more resilient to flooding, drought and climate change, and which delivers enhanced biodiversity and natural services. The project team has been working with local landowners, community groups, volunteers, the Adur and Ouse Catchment Partnership and many other stakeholders since 2012.
