Description habitat

This habitat type consists of peat-forming communities developed at the oligotrophic to mesotrophic water surfaces, with characteristics intermediate between soligenous and ombrogenous types. They present a large and diverse range of plant communities influenced by base-rich groundwater or surface water, which mixes with acidic, oliogotrophic precipitation. Two vegetation types are included in this habitat type in The Netherlands: 1) Quaking bog (association Scorpodio-Caricetum diandrae) and 2) Peat bog (association Pallavicinio-Sphagnetum). These communities are a developing stage of the hydrosere of ditches and peat pits in low laying peat areas. They are preceded by H3150 - Natural eutrophic lakes with Magnopotamion or Hydrocharition -type vegetation and succeeded by bush or forest, and possibly swamp heath #2.
