Seagrass Survey

Seagrass Map

Did you know that there are several seagrass beds in St Kilda Harbour?

Seagrass is different from seaweed. It is a flowering plant and an important part of the marine ecosystem. It provides food and shelter for marine life, stabilises the loose sediment on the sea bed and also absorbs carbon dioxide. (World wide, seagrass beds trap carbon in the sediment and contribute to a slowing of global warming). It is also a species which provides an early warning of change and potential problems in the marine environment.


The last survey was undertaken in 2000 (see here). We hope to undertake a new survey in the near future. This will seek to establish the extent of the beds, how healthy they are and what animals and plants are currently living beneath the harbour waters.
