Can I mark the tree in some way eg by a tag or plaque, or placing a rock alongside?
We encourage you to view the planting of a tree as a symbolic act in itself. Once planted, we hope you will consider the tree to be part of a growing woodland, rather than an individual tree. Labels, plaques and other physical markers detract from the appeal of a natural wood and raise issues about who will maintain/remove the labels when they start to look shabby. It is for these reasons that we do not permit the labelling of trees, installation of plaques or other permanent markers. Remember everyone who plants a tree receives a personalised certificate.
