Submerged aquatic plant species
This group includes 5 submerged plant species rooted in sediments. They grow both in standing and running waters but avoid fast flowing rivers and are often associated with nutrient-rich waters. These submerged perennial aquatic plants (also called waterweeds) form dense monospecific populations colonising the whole water column. They cause similar impact as amphibious aquatic plants but cannot colonise habitats outside water. Some of them such as Lagarosiphon major are known to be strong ecosystem transformers, able to increase water pH. Most of these species are poorly consumed by fish. They strongly affect the conservation value of aquatic habitats of EU concern.
