Mr Watson explained that the evidence helped identify critical marine habitats around Sark, including previously unmapped seagrass meadows. This will allow conservation measures to focus on the areas most in need of protection.
Sark’s surrounding waters support a diverse range of marine wildlife, including European spiny lobsters, rays, catsharks, octopuses and pink sea fans.
Mr Watson said the proposed marine protection plan formed part of a wider Channel Islands effort to safeguard the marine environment. Jersey is also considering plans to protect more than 20% of its territorial waters.
He said stronger marine protections could help maintain fish stocks and conserve habitats that support marine biodiversity, benefiting both local wildlife and communities.
He added: “Some of these habitats are very important for extracting and trapping carbon.”
Sark’s proposed marine protection measures still require political approval. Members of the Chief Petitions Group are due to discuss the plan on 30 September.
