Hard oligo-mesotrophic waters with benthic vegetation of Chara spp
Lakes and pools with waters fairly rich in dissolved bases (pH often 6-7) (Pal. 22.12) or with mostly blue to greenish, very clear, waters poor (to moderate) in nutrients, base-rich (pH often >7.5) (Pal. 22.15). The bottom of these unpolluted water bodies are covered with charophyte, Chara and Nitella, algal carpets. In the Boreal region this habitat type includes small calcareous-rich oligo-mesotrophic gyttja pools with dense Chara (dominating species is Chara strigosa) carpets, often surrounded by various eutrophic fens and pine bogs.

EU conservation status
Conservation status assesses every six years and for each biogeographical region the condition of habitats and species compared to the favourable status as described in the Habitats Directive. The map shows the 2013-2018 assessments as reported by EU Member State. Assessments are further detailed in the summary document available behind the link below.
