1. The Sphagnum "mosses" in the northern Pennines, recognized by Lewis, are described. 2. They occur on gentle slopes, less than 1 in 30, in an annual rainfall averaging approximately 140 cm. (55 in.). 3. Modification of these "moss" communities, due mainly to burning and grazing, apparently leads to the production of communities dominated by Calluna vulgaris and Eriophorum vaginatum. 4. The soil pH of the typical Sphagnum "moss" is typically between 3.8 and 4.0 but may fall to 3.45 in areas subject to modification and subsequent oxidation.
