Visual surveys for bottlenose dolphins were carried out between June and August 2021 in the West Connacht Coast SAC (Site Code 002998). This SAC was designated in 2013 with bottlenose dolphins as the sole qualifying interest. Dedicated line transects were carried out over seven days on fixed, predetermined routes within the SAC. The survey area was divided into two discrete areas consistent with the boundaries of the SAC; namely the Northern Component and the Southern Component. Both Northern and Southern Components were surveyed on the same day by two different teams. The survey design involved travelling along the coast and inside the islands at both sites, informed by previous work that suggested bottlenose dolphins were rarely found >3km offshore.

Eolas Dualfhoinse	The route of the survey vessel were stored on Garmin handheld GPS. Map files from each survey were downloaded using Garmin MapSource® software and saved as a text file. These data were then used to create ArcView (Version 9) shape files of the survey effort points, tracks, and location of all sightings recorded during each survey. Maps of the study area and associated survey data were created in Irish Grid (TM65_Irish Grid) with ArcMap 10.2 while maps of the prescribed survey area, survey track-lines and coordinates were obtained from DHLGH. Data concerning transects, effort, sightings, abundance and density were stored in a single MS Access database, which was queried and processed via GIS to produce sighting distribution maps.
