Grey Seal Census for North Wales 2017

  • English

  • All

Full-ground based survey of Grey Seals undertaken between Aberystwyth and the Dee Estuary aimed to identify potential and active pupping sites throughout the North Wales and to estimate pup production for the 2017 season. All active and newly identified potential pupping sites were surveyed in 7 to 10 day cycles by boat, sea kayak and on foot. A drone was used to supplement pup counts and to quantify sampling error at The Skerries. A total of 126 potential and previously recorded pupping sites along the North Wales coast were defined

Surveys were largely conducted using coastal walkover surveys and vessel-based surveys. A trial survey using an unmanned aerial vehicle (UAV) was also conducted to assess the efficacy of this method in comparison to the principal methods used (Ocean Ecology, 2018a)
