Low or variable salinity habitats - Submerged fucoids, green or red seaweeds (low salinity infralittoral rock) (Priority Marine Feature) (SNH WMS)

The Priority Marine Feature (PMF) list contains 81 habitats and species considered to be of conservation importance in Scotland's seas. It includes many features which are characteristic of the Scottish marine environment, ranging from flame shell beds in coastal waters, to cold-water coral reefs of the deeper seas, and mobile species such as minke whale and basking shark.

This layer shows the distribution of submerged fucoids, green or red seaweeds (low salinity infralittoral rock). This is a characteristic lagoon community dominated by dense seaweeds with a very restricted fauna due to the low salinity. It is unique to Scotland where there are numerous records from the Outer Hebrides, Orkney and Shetland. Scotland is of national importance for this habitat.
