| Abstract | The last national estimate of common seal population was approximately 3000 in 1989 / 90 (Harrington, 1990). A recent NPWS sponsored aerial survey has estimated the 2003 population at 2905 common seals (Cronin et al. 2004). This recent survey whilst not directly comparable to previous surveys due to changes in methodology identifies a shift in the importance of common seal populations. In particular, it notes the increasing national significance of common seal populations on the south-west coast of Ireland. Recommendations are made for the continuation of regular seal surveys at certain locations and for the augmentation of survey effort at other sites. |
