Risley Moss peat accumulation filled the depression, allowing colonisation by bog mosses such as the "Sphagnum" varieties, thus giving rise to the name "moss". Risley Moss is one of only two mosses in Cheshire where the water level has been deliberately raised in an attempt to encourage the regeneration of an active bog surface. The long-term restoration project to re-wet the moss began in 1978 and was completed in 2002. This scheme was undertaken to create a series of scrapes and bunds to retain water and recreate the perfect conditions for bog flora such as cotton grass and sphagnum mosses to re-colonise
Sphagnum fuscum Endangered species lists within some German states. Switzerland has labelled "S. fuscum" as vulnerable. In the United States, "S. fuscum" is reported to be at risk in the state of North Carolina. Across Europe, "S. fuscum’s" habitats are under protection. Germany and Switzerland have both placed the moss under “special protection.” This species is associated with "Sphagnum angustifolium", "S. fallax", "S. magellanicum", "S. papillosum", more infrequently with "S. teres", and "S. warnstorfii" in richer sites. "Sphagnum fuscum" is easily discernible from other species of Sphagnum, as it tends to be reddish brown in color, and is more likely to form
