Lochaber contains internationally important sites for blanket bog, including Claish Moss, Kentra Moss and Rannoch Moor with their distinctive pool and hummock typography. Claish Moss is classified as an ‘eccentric’ mire', and the vegetation is dominated by Sphagnum mosses, with over 14 Sphagnum species being recorded from the site, including Sphagnum imbricatum and S. pulchrum. Other notable species include the liverwort Pleurozia purpurea and brown beak-sedge (Rhynchospora fusca). Claish Moss and Kentra Moss also support variable amounts of heather, bog myrtle (Myrica gale), bog asphodel (Narthecium ossifragum), cotton-grasses (Eriophorum vaginatum and E. angustifolium) . Insectivorous sundews (Drosera spp) and bladderworts (Utricularia spp) are found in the bog pools and margins. The nationally scarce dragonflies, the northern emerald (Somatochlora arctica) and the azure hawker (Aeshna caerulea) breed in the bog pools. The blanket bog at Kentra Moss merges into the saltmarsh at Kentra Bay, with its characteristic dendritic channels.
Rannoch Moor contains an extensive area of blanket bog and valley and soligenous mire. The blanket bog has a characteristic knoll and valley topography, with small compartments separated by ladder fens. Rannoch Moor is also noted for an unusual ecological variant of transition mire. It has distinctive bog pool community and supports the endemic Rannoch-rush (Scheuchzeria palutris).
Bog, bog, beautiful bog!
