Additional information

Intertidal Zostera marina beds may be damaged by frost, although rhizomes most likely survive. In carbonate based sediments phosphate may be limiting due to adsorption onto sediment particles. Zostera marina is also found in reduced salinities, for example brackish lagoons (Dyrynda, 1997).
