As part of the Shetland Islands Regional Marine Plan (SIRMP) the Marine Spatial Planning Team monitor the occurrence of introduced marine species (also known as non-native species) in Shetland. This supports the Biosecurity Plan for the Shetland Islands.
What are Non-native Species?
Non-native species are plants and animals which originate elsewhere, e.g. Asia or America, but have been brought to the UK through man’s activities. Not all introduced species are problematic, but some species can impact upon the marine environment and upon our marine industries, such as aquaculture and fisheries.

Where do they Grow?
Many non-native species grow on man-made surfaces, and will foul boat hulls, ropes, buoys and other structures. Many will also grow on other plants and animals, including mussels. The climate change indicator species live along the shore and in rock-pools, as well as on man-made structures.
There are now a number of non-native species in Shetland which have been introduced to the marine environment, some of which have been here for several decades and have been slowly spreading around the coast, and some which have been introduced more recently. A non-native species monitoring programme is undertaken by Shetland UHI, with Shetland wide monitoring starting in 2012.
More information on how the Marine Spatial Planning Team monitor for invasive species on our Monitoring page.
There are many ways you can get involved, from active monitoring of non-native species to practicing good cleanliness and anti-fouling of equipment when using the marine environment.
As part of the project, we have developed leaflets for the general public, aquaculture industry, and marinas and marine users, which contain further information on several non-native species, and advice on what you can do to limit their spread and impact on Shetland.
More information can be found on our How to Get Involved in Invasive Species Monitoring page.
