A consultation is under way into whether measure to protect birds from dogs should continue at a Norfolk nature reserve.
Rare species breed or spend the winter at Dersingham Bog, near King's Lynn.
Ground nesting species using the site include the nightjar, woodlark and tree pipit; while raptors including hen harriers, merlins and short-eared owls also roost there.
In 2006, Natural England ordered dog owners to keep their pets on a lead whilst on the site, which borders the Queen's Sandringham Estate.
It says since then the order has helped safeguard breeding birds on the reserve, which is now home to one of the widest ranges of species in Norfolk.
It wants to be allowed to continue the regulation but must carry out a public consultation.
