Annex I habitats that are a primary reason for selection of this site

  • Oak Mere, in the West Midlands of England, is a lake formed within sediments that are low in nutrients and oligotrophic. It is a large waterbody that has formed in a kettle hole in the fluvio-glacial sands of the Cheshire Plain. The site has clear water of low nutrient status characteristic of oligotrophic waters and a marginal zone of shoreweed Littorella uniflora. The site supports an assemblage of plants that are now rare in the lowlands of England, including floating mats of bog-moss Sphagnum spp. and the scarce narrow small-reed Calamagrostis stricta.

  • Open water and peat deposits lie in this kettle-hole depression within Delamere Forest, and peat-cutting has given rise to additional pools and fens. The water is acidic, but slightly nutrient-rich. There are transitions at the water’s edge with soft rush Juncus effusus, water horsetail Equisetum fluviatile, common spike-rush Eleocharis palustris, marsh pennywort Hydrocotyle vulgaris, the moss Drepanocladus fluitans and bulrush Typha latifolia. Small depressions in the peat are occupied by bottle sedge Carex rostrata, common cottongrass Eriophorum angustifolium, purple moor-grass Molinia caerulea, cross-leaved heath Erica tetralix and round-leaved sundew Drosera rotundifolia.
