Metadata: 2003 Scottish Natural Heritage (SNH) Mousa broad-scale mapping survey
Abstract:
Mousa was identified as a candidate Special Area of Conservation (cSAC) because of the presence of a large breeding colony of common seals, Phoca vitulina, a species listed in Annex II of the EC Habitats Directive; and for the presence of â??reefsâ?? and â??submerged and partly submerged sea cavesâ??, habitats that are listed in Annex 1 of the EC Habitats Directive. Mousa cSAC supports one of the largest groups of common seals in Shetland and one of the most northerly groups in the UK. The reefs and sea caves within Mousa cSAC are considered highly natural and representative of the Shetland environment. The seaward boundary extends to a minimum distance of 500m offshore, using the simplest straight-line boundaries possible. The boundary for the cSAC also includes all offshore rocks and skerries (Figure 1.1). The intertidal areas up to mean high water springs around the island are also included within the cSAC. The present survey visited the island of Mousa cSAC in August and September 2003 with the aim of providing a comprehensive broad scale intertidal and subtidal biotope distribution map of Mousa cSAC. Particular emphasis was placed upon the mapping and recording of the reef and cave communities present on the island. Intertidal surveys of the island were supplemented by the use of acoustic ground discrimination system (AGDS) mapping techniques of the subtidal area. Photography, video footage and illustrations were used to illustrate habitats, communities and species.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The implication of the lack of aerial data has been minimised as far as possible by careful manipulation and interpretation of existing photos. However, new aerial photos would have provided a contemporaneous record of the site and survey and may have allowed more detail to be transferred to the field wireframe maps. It is felt that the additional time and detail invested by the field surveyors in utilising two tides on most survey days has compensated for the inability to acquire more up-to-date aerial photography in terms of data density and data quality. On return from the fieldwork, the hand-drawn maps were digitised into ArcView GIS. Biotopes have been coloured in accordance with the JNCC guidelines (Connor et al., 1997a). Due to the narrowness of the shoreline and the vertical zonation of biotopes, on much of the island the shore has been mapped to â??habitat complexâ?? level rather than to biotope. In these areas, regular shore profiles have been produced to illustrate the biotopes present, their position on the shore and the relative extent up the shore. These are presented as a separate layer in the GIS. The video data was captured using an Accessâ?¢ database (Figure 2.7). The video tapes were replayed and at least one frame grab was captured for each video drop. The frame grabs were stored in a sub-table linked to the master table. Notes were taken in a systematic way recording main habitat features, conspicuous species or, where this detail was not possible, general growth forms and higher taxonomic categories. The biota was also scored from 1 to 5 to show their relative abundance. The species were recorded in a sub-table linked to the master table so that site/species tables could easily be extracted (see Figure 2.7). The notes were first made on paper and then the tapes were replayed and the notes entered into a database, but with entries for biotope codes and habitat categories left blank. The final stage consisted of reviewing the database, frame grabs and if necessary the tapes, in order to tag the records with biotope codes and habitat classes. This staged process to biotope recording and the use of look-up tables for codes and terminology was designed to promote consistency in classification of the records. |
