SNH Commissioned Report 894: Harbour seal haul-out monitoring, Sound of Islay

This report provides an overview of the current techniques available for monitoring seal haul-out sites with a particular focus on those at the Sound of Islay. It describes the results of boat based disturbance trials undertaken at selected, non-designated, haul-out sites in the Sound, using time-lapse photography and telemetry to track subsequent seal movements. Based on this, a simple, time lapse photography based method of haul-out monitoring is described that should provide sufficient information to identify and characterise any boat based disturbance events. Though based upon haul-outs within the Sound of Islay, the approach described may be readily adapted and employed elsewhere.
