Information on Eelgrass

It is very important to follow the route and marshal’s instructions for this event due to the special natural environment and in particular to protect eelgrass. Eelgrass has distinct importance to the area as it provides food for nationally important numbers of wintering birds such as Dark Bellied Brent Geese, Grey Plover and Knot.

Along with a food source, they create underwater meadows with support diverse ecosystems. They act as spawning and nursery sites for fish and provide shelter for tiny invertebrates, marine mammals and waterfowl. The root systems stabilize sediment and the plants themselves sequester CO2 efficiently with 1 hectare of seagrass storing up to two tonnes of CO2 per year.

Essex Wildlife Trust states the best way to protect seagrass is to avoid anchoring in seagrass areas and minimize disturbance from mooring, avoid trampling and other activities that disturb sea grass and spread the word.

For more information please visit the Essex Wild Life Trust Sea Grass project where they explain the benefits of the eelgrass, what they are doing to protect this habitat and what you can do to help seagrass.
