Annex I habitats that are a primary reason for selection of this site
7130 Blanket bogs (* if active bog) * Priority feature
Hascosay is one of the few remaining un-eroded pool systems in Shetland. The blanket bog on Hascosay is remarkably intact and supports a range of shallow mud-bottomed, as opposed to Sphagnum-filled, hollows. A particular feature of this site is the dominance of the moss Mnium hornum, often accompanied by Aulacomnium palustre around the margins of bog pools. This combination of features is unusual in the UK. Sphagnum fuscum adds to the diversity of the community and is indicative of the undamaged nature of the bog.
