Project summary

Edit project overview to modify the project summary.

The purpose of the Project was to enhance river habitat along a 150m stretch of the R. Wye that borders Bourne End Recreation Ground in Buckinghamshire. Through a combination of tree management work and the installation of Woody Habitat structures, the scheme narrowed the previously over-wide channel and increased heterogeneity of flow and habitat. The scheme was designed to directly contribute to the R. Wye achieving Good Ecological Status under the Water Framework Directive. This project was one of three habitat enhancement Projects completed on the river in 2016 supported by the Catchment Partnership Action Fund. The Project was managed by the Chilterns Chalk Streams Project (CCSP) working in partnership with the Chiltern Rangers CIC, Environment Agency, Wooburn Green & Bourne End Parish Council under the banner of Revive the Wye a local community initiative. The work as carried out using a combination of specialist contractors (tree work) and volunteers. The project was funded by the CCSP, the Catchment Partnership Action Fund and the Chiltern Rangers CIC.

Reasons for river restoration

Mitigation of a pressure
Hydromorphology Supporting elements: not-high
Biology Fish populations: poor
Physico-chemical Phosphate: moderate
Other reasons for the project lack of habitat diversity, poor macrophytes, improve local park


Structural measures
Bank/bed modifications Creation of pools, Fish habitat restoration, Introducing large woody debris, Habitat restoration
Floodplain / River corridor Habitat creation, Tree management
Planform / Channel pattern Channel narrowing, Re-meandering
Non-structural measures
Management interventions
Social measures (incl. engagement) Community involvement
