Just as a reminder for leaders who are contemplating or running walks in Forestry Commission area of eastern England. They are advised to check:
https://www.forestry.gov.uk/forestry/beeh-9vnet5
To see whether there are any temporary Closures of Forestry Commission work areas.
This site is updated perhaps monthly and has maps of work areas, but other work also goes on at short notice and leaders need to take account of local instructions beside tracks.
