Hermaness, Saxa Vord and Valla Field SPA is located at the northernmost part of the Shetland island of Unst, Scotland, the most northerly part of the UK. The vegetation of Hermaness is mainly Calluna/Eriophorum blanket bog, with acidic grassland together with small oligotrophic lochans and streams. More species-rich closely grazed, maritime grasslands line the cliff tops. The cliffs of Hermaness, Saxa Vord and the off-lying stacks (including Muckle Flugga) are mostly 100-200 m high. The site is important for a number of breeding seabird species that nest on both the extensive cliffs as well as on the heathland and grassland parts of the site. The seabirds feed outside the SPA in nearby waters, as well as more distantly elsewhere in the North Atlantic.
