A district Wildlife Site

Managed by the BOS on behalf of Thames Water

3.5ha site of Scots Pine and Alder, originally planted by the Forestry Commission, laterly enhanced by areas of varied shrubs planted by the BOS.

A mixture of birds has been recorded from the site, including wintering Siskin and Lesser Redpolls and warblers in the summer.

The site is adjacent to Grimsbury Reservoir which is a popular dog walking area. BOS requests that dog walkers keep their dogs on short leads should they enter the woodland, particularly during the breeding season.

Anyone wanting to help maintain this reserve should contact Reg Tipping for dates of work parties.
