4. Channel restoration - Box Moor near Hemel Hempstead

Aims: Improve wildlife corridors; Manage flow

Water body: River Bulbourne
Project description

Project to restore a 1km length of the R. Bulbourne between the Grand Union Canal and Two Waters Road, Hemel Hempstead.

 The River Bulbourne at Box Moor has been extensively modified historically as a result of land drainage, agriculture, milling and through the construction of the Grand Union canal in 1797.  The current course has been straightended, dredged, widened and impounded in various places, which has led to an artificial river channel unable to support the diversity of wildlife typically found in chalk streams. In addition, unrestricted grazing of the banks has contributed to erosion and left little in the way of marginal vegetation which is so important for the health of the river.  

To address these issues the Box Moor Trust, Chilterns Chalk Streams Project and Environment Agency are working together on a project to restore the Bulbourne to a more natural chalk stream.  The scheme will involve creating a narrower, more sinuous channel using locally sourced material to create a new course within the existing channel and re-grading the banks in behind the new bank edges, reconnecting the river with its floodplain.  In addition, wetland scrapes will be created to provide additional habitat and work will be carried out to repair the fords to allow livestock and vehicle movements and prevent erosion in the future. 

To protect the restored channel, new fencing will be installed to control grazing on the site.

The scheme is due to be carried out in two phases, with the first beginning in January 2017.
