Sphagnum fuscum hummocks. Known occurrence of "Sphagnum fuscus" are on the map above. The moss inhabits boreal forests and marshlands primarily, and is more likely to be found in colder climates. The moss is also capable of inhabiting areas of relatively high elevation. In recent studies performed in Eastern Europe, it was found that stable carbon and oxygen isotope ratios in α-cellulose of "Sphagnum fuscum" stems subsampled from hummocks and peat plateau profiles are useful indicators for summer temperature and winter precipitation at decadal to millennial timescales. In another study conducted in Alberta, Canada, it was found that "S. fuscum" serves as
Blawhorn Moss National Nature Reserve area by the International Union for Conservation of Nature, and is also designated as both a Special Area of Conservation and a Site of Special Scientific Interest. The reserve is owned and managed by Scottish Natural Heritage (SNH). Blawhorn Moss provides an important habitat for wildlife and supports many of the plant species representative of bog habitat. A number of sphagnum mosses grow here, as well as heather, crowberry, hare’s-tail cotton grass and common cotton grass. A variety of bird species breed on the moss, including red grouse, snipe, curlew and redshank. Stonechat, skylark and meadow pipit are also regularly
