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
Sphagnum taken during the harvesting of "Sphagnum" to ensure enough moss is remaining to allow regrowth. An 8-year cycle is suggested, but some sites require a longer cycle of 11 to 32 years for full recovery of biomass, depending on factors including whether reseeding is done, light intensity, and the water table. This "farming" is based on a sustainable management program approved by New Zealand's Department of Conservation; it ensures the regeneration of the moss, while protecting the wildlife and the environment. Most harvesting in New Zealand swamps is done only using pitchforks without the use of heavy machinery. During transportation,
