Bottlenose Dolphin Survey Lower River Shannon cSAC, 2010
A population assessment of the bottlenose dolphins in the Lower River Shannon candidate SAC was undertaken between July and October 2010. Dolphins were located on each transect. During 12 transects a total of 64 dolphin groups were encountered with 547 individuals recorded. Group sized ranged from 1-50 overall. Lone dolphins were reported on two occasions. Dolphins were located throughout the survey area with concentrations off Kilcredaun Head, Kilbaha, Leck Point in the outer estuary and Carrig buoy in the middle estuary.

- Purpose
-
The purpose of the is Project was to provide a population assessment for Bottlenose dolphins in the Lower River Shannon SAC. Previous abundance estimates for bottlenose dolphins in the Lower River Shannon cSAC ranged from 114 in 2008 to 140 in 2006. The present estimate is lower but lies within the 95% Confidence Intervals for all surveys carried out to date. This suggests that, within the power of the survey technique, the population of bottlenose dolphins in the Lower River Shannon cSAC is relatively stable.

The route of the survey vessel and position of dolphin schools encountered was recorded on a hand-held Garmin 72 GPS and tracks and waypoints downloaded using Garmin MapSource® software. All dolphin schools, defined as all dolphins within 100m radius of each other (Irvine et al., 1981), were recorded and a waypoint entered on the GPS at the start and end of a group encounter. This recorded time as well as location. Each group was approached slowly and group size recorded as the total number of individuals present. The number of adults, juveniles (sub-adults) and calves within the group were recorded.
