Waveney and Little Ouse Valley Fens
When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|6410 Molinia meadows on calcareous, peaty or clayey-silt-laden soils (Molinion caeruleae)|
|This site represents M24 Molinia caerulea – Cirsium dissectum fen-meadow associated with spring-fed valley fen systems in East Anglia, where Molinia grassland is very rare. The Molinia meadows are found here in conjunction with M13 Schoenus nigricans – Juncus subnodulosus mire and 7210 calcareous fens with Cladium mariscus. Where the fen-meadow is grazed it is more species-rich, with frequent southern marsh-orchid Dactylorhiza praetermissa.|
|7210 Calcareous fens with Cladium mariscus and species of the Caricion davallianae * Priority feature|
|This site occurs in the East Anglian centre of distribution of calcareous fens and contains very extensive Cladium beds, including managed examples, as well as stands in contact zones between small sedge mire and species-poor Cladium. The habitat type here occurs in a different hydrological situation to the Broads – spring-fed valley fen rather than flood-plain mire.|
