Consultation identifies North Devon coastline as one of five UK Special Areas of Conservation (SACs) sites.
North Devon could become a special marine site to protect harbour porpoises.
The Bristol Channel has been identified as one of five possible Special Areas of Conservation (SACs) sites around the UK.
A drop-in event will be held in Bideford this month for people to find out more about the proposed SACs.
Nikki Taylor, marine mammal adviser for event organisers, the Joint Nature Reserve Committee, said: “These events will provide an informal opportunity for anyone with an interest in the sites to come and discuss them with relevant members of staff who will be on hand to help.”
The harbour porpoise is a protected species and can be seen regularly around the North Devon coastline.
In 2014 the Gazette reported how Devon Wildlife Trust was calling for North Devon to become a protected area for species.
The consulation process by JNCC and Natural Resources Wales (NRW) on the proposed sites will run until May 3.
Drop in to the event at The Burton in Bideford from 6-8pm.
