This habitat includes aquatic vegetation in non-brackish water dominated by macrophytic green algae of the class Charophycae, including the genera Chara, Lychnothamnus, Nitella, Nitellopsis and Tolypella. They occur in lakes, ponds, and both permanent and periodic pools. They are competitively weaker than vascular plants, therefore, they often colonize initial successional stages or aquatic habitats of short duration.
