Carrington Moss of years this raises the level of peat and forms a gently sloping dome (hence, raised). Such areas support a wide range of flora and fauna; "Sphagnum balticum", a medium-sized bog moss, was recorded on Carrington Moss in the 1880s, although locally it is now presumed to be extinct. Lancashire- or bog asphodel ("Narthecium ossifragum"), white beak-sedge ("Rhynchospora alba"), cranberries, bog-rosemary ("Andromeda polifolia"), and the cotton sedge have also been recorded. In 1923 species of trees recorded by E. Price Evans for the "Journal of Ecology" included English oak ("Quercus robur"), and common ash ("Fraxinus excelsior"). Undergrowth included common hazel
Moss in cities. Examples would be "Rhytidiadelphus squarrosus", a garden weed in Vancouver and Seattle areas; "Bryum argenteum", the cosmopolitan sidewalk moss, and "Ceratodon purpureus", red roof moss, another cosmopolitan species. A few species are wholly aquatic, such as "Fontinalis antipyretica", common water moss; and others such as "Sphagnum" inhabit bogs, marshes and very slow-moving waterways. Such aquatic or semi-aquatic mosses can greatly exceed the normal range of lengths seen in terrestrial mosses. Individual plants or more long are common in "Sphagnum" species for example. Wherever they occur, mosses require liquid water for at least part of the year to complete
