The bog is 6 metres deep in places and has all the characteristics of a raised bog its domed top is covered by heather, cotton grass and varieties of sphagnum, with the drier margins fringed with trees. The Moss is continually under threat from invading birch and Scots pine which, if not cleared away at regular intervals, would gradually take over the area and change it from bog to woodland.
