Online only
This chapter deals with Common Standards Monitoring (CSM) for marine mammals on designated sites, including SSSIs, ASSIs and Special Areas of Conservation (SACs).


Grey seal Halichoerus grypus © Paddy Pomeroy, SMRUIt provides guidance on the identification of attributes and targets for marine mammals where these are notified or qualifying interest features, together with advice on monitoring methods, with specific guidance for the following species:
  • Grey seal Halichoerus grypus
  • Harbour seal (also known as common seal) Phoca vitulina
  • Bottlenose dolphin Tursiops truncatus
Currently, consideration is also being given to the inclusion of the harbour porpoise (Phocoena phocoena). Should protected sites be designated, then guidance for this species will also be incorporated.
