We report high rates of site use and site occupancy by this species during the summer. Although trends in site use may not reflect population trends in the wider region, these data were consistent with recent abundance estimates that indicate that the number of bottlenose dolphins using Cardigan Bay is stable or slightly increasing.

Recreational boating is known to have the potential to cause disturbance to cetaceans and this monitoring study provides data that underpins the effectiveness of management. notPlanned Liz Allan Department of Environmental Services & Housing, Cyngor Sir Ceredigion County Council Primary contact liza@ceredigion.gov.uk NA NA NA Liz Allan owner NA zd_716 2025-07-31T15:32:48-04:00 dataset Allan, L. 2011.
