Principle

Bogs and fens are habitats of plants that are specialised in soils with constant excess water. Apart from this specialisation, bogs and fens differ significantly from each other. Raised bogs and fens, for example, have different plant communities, which is due to their varied conditions of life that are examined in this experiment.
