10. Restoring the Cornmill Stream and Meadows

Theme: Ecology and morphology


  • Improve riverine and riparian habitat

Project description

This project aims to improve the hydrology and habitats of the Cornmill Stream and Cornmill Meadows SSSI.

Cornmill Meadows is one of the best examples of semi-natural floodplain grassland remaining in the Lee Valley Regional Park. Its mosaic of rivers, ditches and pools make this a fantastic place to see a variety of wildlife throughout the year.

However the complex hydrology of the site makes water level management across the floodplain meadows difficult.

This project will survey the Cornmill Stream and Old River Lea at Cornmill Meadows to provide important baseline information that will inform future management of these important watercourses, in line with the aims of the Lee Valley Regional Park Biodiversity Action Plan.

By assessing their hydrology and morphology, the aim is to identify any changes to the flow requirements to enhance the ecological condition of this important wetland site. This work will also help inform the development of a Water Level Management Plan for the site.
