Delamere Forest consolidated "schwingmoor" in the process of colonisation by Scots pine. In addition to "Sphagnum" species, common sundew and the locally rare white sedge are present. The site is managed by Cheshire Wildlife Trust and forms part of the Midland Meres and Mosses Ramsar site. Linmer Moss () is unusual within Delamere Forest in having a fen environment which is not dominated by "Sphagnum" species. The vegetation is predominantly tussock sedge and reedmace. Marsh fern and white sedge, which are rare in Cheshire, are found here; other species include cuckooflower, marsh bedstraw, marsh cinquefoil and "Sphagnum squarrosum". The site has experienced
