Priority marine features in Scotland's seas

Priority marine features (PMFs) are habitats and species that we consider to be marine nature conservation priorities in Scottish waters.

In July 2014, Scottish Ministers adopted a list of 81 priority marine features (PMFs) – many of which are features characteristic of the Scottish marine environment. PMFs range from flame shell beds in our coastal waters to the cold-water coral reefs of our deeper seas and mobile species such as minke whale and basking shark.

Other protection

PMFs may also be protected under legislation or by other designations.

How the list is used

The list helps to deliver Marine Scotland’s vision for marine nature conservation, as set out in A Strategy for Marine Nature Conservation in Scotland’s Seas

The list will be used to help:

  • focus future conservation action and marine planning
  • direct research and education
  • promote a consistent approach to marine nature conservation advice

Why the list was developed

Scotland’s coasts and seas are among the most biologically productive in the world. They support an estimated 8,000 species of plants and animals – and up to 40,000 species if you include microscopic organisms. New species are still being discovered, particularly in deeper waters to the north and west.

How the list was developed

NatureScot and the Joint Nature Conservation Committee worked with Marine Scotland to develop the list.

To produce the list, we assessed species and habitats on existing conservation schedules against criteria that considered:

  • whether the species/habitat occurs in significant numbers in Scotland’s seas
  • whether the species/habitat is under threat or in decline
  • the functional role that the species/habitat plays

The process and list were developed in consultation with a range of specialists, including through targeted external peer review in 2010. The list was also subject to public consultation in 2013.
