Guests to Hunstanton Sea Life Sanctuary are being urged to help gain protected status for an important area of local marine habitat.
The Wash Approach is an area of sandbanks, gravel and worm reefs and provides a rich feeding area for porpoises, grey and common seals and many species of fish.
In a bid to make the area a Marine Conservation Zone, Sea Life visitors will be encouraged to sign postcards which will be delivered to the appropriate government decision-makers in December.
In the past, Sea Life has helped the Marine Conservation Society (MCS), among others, persuade the government to approve 50 UK coastal marine conservation zones.
But the MCS believe that another 34 sites are necessary, which includes the Wash Approach, so that the protected areas can help safeguard our native marine life for the future.
Displays supervisor Kieran Copeland said: “Given that this is such an important habitat for seals in particular, and we spend so much of our time rescuing and rehabilitating sick or abandoned seal pups, this is a mission very close to our hearts.
“If successful, it would be strong reassurance that the environment we are returning all those seals to is secure for the foreseeable future, and a safe healthy habitat both for them and the diverse other marine life it supports.”
