Sphagnum palustre less frequent just North of London and west through to Bristol and patches in the Republic of Ireland. It is widespread in Scotland, Wales, Orkney, Shetland and the Isle of Man. It can be found on Scilly. "Sphagnum palustre" is not on the IUCN red list of threatened species and therefore isn’t considered to be threatened or endangered. In a project called Mossclone which is part of the 7th framework program of the European Union the peat moss "Sphagnum palustre" will be multiplied in moss bioreactors to create a measuring tool to track air quality in Europe.

Carnivorous plant more or less than this optimum will take up less carbon dioxide than an optimal plant, and hence growing less well. These plants will be at a selective disadvantage. At zero investment the growth is zero, because a non-carnivorous plant cannot survive in a habitat with absolutely no soil-borne nutrients. Such habitats do not exist, so for example, "Sphagnum" absorbs the tiny amounts of nitrates and phosphates in rain very efficiently and also forms symbioses with diazotrophic cyanobacteria. In a habitat with abundant soil nutrients but little light (as shown above), the gross photosynthesis curve will be lower and flatter,
