Hard oligo-mesotrophic waters with benthic vegetation of Chara spp
Description (English)
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.
