The Mersey Valley is a joint countryside management project covering the river and surrounding land between the Manchester/ Stockport boundary and the Manchester Ship Canal in Irlam.
The project is run by a Joint Committee of councillors from Manchester City Council and Trafford Metropolitan Borough Council, along with representatives of the Environment Agency. Its aims are to encourage the use of the Valley for recreation, conservation and agriculture rather than development.
Within the project boundary, the Joint Committee manages nearly 40 sites on behalf of the constituent authorities, totalling 300ha/800acres. The Joint Committee also guides the work of the Mersey Valley Countryside Warden Service, with Manchester City Council acting as managing district.
The Warden Service is responsible for land and visitor management on Mersey Valley sites.
