The island of Sark, in the Channel Islands, has put forward plans to give additional protection to around 30% of its surrounding waters as part of a wider effort to safeguard marine life. The proposal, drawn up by Sark's agriculture, environment and sea fisheries committee with backing from the Blue Marine Foundation, local fishermen and marine experts, aims to protect sensitive habitats while still allowing sustainable fishing to continue. It matters because the area supports species such as European spiny lobster, rays, catsharks, octopus and pink sea fans, and forms part of a broader push across the Channel Islands, including a separate scheme to protect more than 20% of Jersey's waters.

The plan would cover roughly 50 square miles (128.8 sq km) of sea and was developed using evidence that identified important habitats, including previously unmapped seagrass beds, so protection could be targeted where most needed. Freddie Watson of the Blue Marine Foundation said stronger safeguards could help sustain fish stocks, preserve biodiversity and protect habitats that lock away carbon. The proposal is expected to be submitted to Sark's governing body, Chief Pleas, by 1 September, with a debate on the plans due to take place on 30 September.
