SDWF win Shannon dolphin contract

SDWF won a compretitive tender to carry out an abundance estimate.

The National Parks and Wildlife Service (NPWS) advertised a contract on the etenders website, to carry out a survey to estimate the abundance of bottlenose dolphins in the Shannon Estuary. This is the fourth such survey and the SDWF have won this contract for the first time.

The survey involves 12 dedicated transects in the outer and middle estuary between Kilbaha and Killimer/Tarbert. On these transects all dolphins encountered are counted and photographed. Photographs are inspected for unique and permenate markings which identifies individual dolphins. Over the course of each transect new dolphins are recorded and ones recorded previously are re-encountered.

Using programmes called MARK and CAPTURE an estimate of the number of marked individuals in the population can be determined and ultimately the numbers of dolphins in the survey area. Previous surveys have recorded around 120-140 dolphins.

These transect lines will be carried out between July and October with a final report due in November. The SDWF are delighted to have won this contract which demonstrates NPWS confidence in its ability to deliver on important contracts.

The work wil be carried out by Simon Berrow, Joanne O'Brien, Aoife Foley, Kerstin Voigt and Florence Erbs.
