The 2015 National Survey of Hen Harriers (the fourth national survey since 1998-2000) has shown that the Irish population has experienced further declines, including within some former strongholds for the species. The 2015 survey showed there are between 108 and 157 breeding pairs across Ireland, down by 8.7% since the last survey in 2010. However, increased survey effort complicates comparisons, and if only those squares surveyed in all years are taken into account a bleaker picture is painted.
