About

Zostera noltii is a species of seagrass known by the common name dwarf eelgrass. It is found in shallow coastal waters in north western Europe, the Mediterranean Sea, Black Sea, Caspian Sea and Aral Sea and on islands in the Atlantic off the coast of northwest Africa. It is an important part of the intertidal and shallow subtidal ecosystems of estuaries, bays and lagoons.

Where it grows

Zostera noltii is found in the eastern Atlantic Ocean along the coasts of Europe as far north as Norway, Sweden and the Baltic Sea. Around the British Isles it grows extensively in the Firths of Moray and Cromarty, the Wash and the Thames Estuary. In Ireland substantial quantities are found in Strangford Lough, Dungarvan Harbour and Dublin Bay. In the Mediterranean Sea and the Black Sea, it is restricted to the brackish conditions found in lagoons and estuaries. It is the only species of seagrass found in the Caspian Sea and the Aral Sea. It also grows in Morocco, Mauritania, and the Canary Islands, with the southernmost known population in the Saloum Delta in Senegal. It grows intertidally on fine sandy or muddy substrates and can tolerate various levels of salinity. It tends to grow in a band higher up the beach than Zostera marina beds and is often mixed with other seagrasses (Ruppia spp.). It grows subtidally in deeper water when it is in low salinity or brackish water in estuaries and lagoons. It is adversely affected by high nutrient levels and cloudy water.
