  Nature and importance of the Zostera biotope complex
Status of Zostera species in the UK ‘Seagrass’ is a common name for a large group of higher flowering land plants that have spread into the marine environment in relatively recent geologic times.
A clarification of the taxonomic status of Zostera species and a re-examination of specimens would contribute to an increased understanding of the distribution and habitat requirements of the three forms, with important implications for their future management.
Zostera beds are an important source of food and shelter for the young stages of many fish and crustacean species, some of which are themselves food for commercially-valuable fishery species.

Zostera is an important component of the diet of Brent geese (Branta bernicla), wigeon (Anas penelope), mute and whooper swans (Cygnus olor and Cygnus cygnus).

 Zostera in Tomales Bay
The elemental content of Zostera marina leaves in Tomales Bay was quite variable (Table 1), but was within the range of values reported in the literature.
The spatial trend in nitrogen content of seagrass leaves observed during summer 1992 suggested that N availability for Zostera marina was high near the mouth of the bay, and decreased towards the head of the bay ((Figure 3)).
This decrease may be a result of the increased dependence of the seagrasses on respiratory CO from the remineralization of organic matter from phytoplankton and terrestrial sources, similar to the finding of Lin et al.

 Aquatic Plant Ecology at the Center for Applied Aquatic Ecology
Seasonal dynamics of plants such as water willow Justicia americana, seagrass Zostera marina L.and communities of microorganisms (algae, bacteria) are influenced by natural factors like oxygen limitation, nutrient loading, and human influences such as habitat deterioration and elevated concentrations of toxicants.
Zostera marina L. Cultural eutrophication and global warming are among the most studied processes relating to anthropogenic perturbations in estuarine systems, and continue to be a major concern for environmental scientists/ managers.
By reducing shoot density, decreasing leaf and root development, and altering internal carbon and nitrogen compositions, there may be significant reductions in the growth and development of Zostera marina L. For more details on this experiment, please go to our Publications page.

Recognizing Zostera is not hard - they have thin leaves about 12 to 20 inches long (31 to 53 centimeter) with parallel edges and three veins running along their length.
So important is Zostera's role in this food cycle that estimates reveal that more than 20 species of commercially valuable fish species feed in these eelgrass meadows at some point in their lives.
