Waterway Survey 2007
In 2007 310 volunteers carried out the Waterway Survey at 362 sites. This survey involves walking along a 1km stretch of waterway and counting Daubenton's bat passes. This species was recorded at 293 sites (81% of sites surveyed).
Data from the All Ireland Waterway Survey, co-ordinated by Bat Conservation Ireland, has been included again this year, increasing the site network in Northern Ireland.
The distribution of sites surveyed and Daubenton's bats recorded is shown below (NB each 10km spot may contain more than one survey site; where Daubenton's bat was not recorded it does not necessarily imply that this species is absent from the 10km square).
