Concept: Permanent oligotrophic lakes, ponds and pools in the eunishabitats vocabulary

Concept URI	http://eunis.eea.europa.eu/eunishabitats/C1.1
Preferred label	Permanent oligotrophic lakes, ponds and pools
Definition	Waterbodies with a low nutrient (nitrogen and phosphorus) content, mostly acid (pH 4-6). Includes oligotrophic waters of medium or high pH, e.g. calcareous and basic unpolluted nutrient-poor lakes and pools, which are rare in much of Europe and noted as a habitat of charophytes (C1.14). Excludes peaty, dystrophic waters (C1.4). Because of the low nutrient status, beds of vascular plants, including [Callitriche] spp., [Potamogeton] spp. and isoetids [Isoeto-Nanojuncetea] are often sparse and open.
