The Status of the Harbour Seal Phoca vitulina L. in Inner Bantry Bay, Co Cork and Inner Kenmare River, Co Kerry: 1964-2004

Harbour seals Phoca vitulina L. in inner Bantry Bay and inner Kenmare River were surveyed on a regular basis from 1985-2004. These data, along with historical records from 1964-1984, are reviewed. There was a significant positive linear relationship between year and count. Overall, the data show that between 1985 and 2004 the population of harbour seal in the count areas increased by 298% (Bantry Bay) and 354% (Kenmare River). The two bays are now among the most important sites for harbour seal in Ireland. The results are discussed in relation to pressures on the local harbour seal population including persecution, disturbance and phocine distemper virus. Harbour seal numbers have increased despite these potential and actual threats.
