Project summary

Edit project overview to modify the project summary.

An initiative of the Nenescape Landscape Partnership the Resilient River project is funded by the Environment Agency & National Lottery Heritage Fund. The primary aim of the project is to enhance, restore and protect the backchannels and backwaters of the Nene Valley through efficient partnership working and best practice.

The River Nene has been highly modified for both flood defence and navigation purposes, historically for industry and in recent times for leisure. This has however, had an impact on the potential for the river to act as an aquatic habitat. The main river, where navigable is much less favourable habitat than the backchannels (historically the main river before modification) for fish, invertebrates & other flora and fauna.

The Resilient River project is in place to connect habitats along the Nene Valley by restoring neglected/altered features, to improve biodiversity; protect, enhance and interpret heritage features; and improve resilience of water quality and supply in the face of population growth, urbanisation and climate change.
