Seal pups lost to deadly storm surge 6 December 2013 Last updated at 17:53 Hundreds of grey seals have been lost on the north Norfolk coast due to the deadly storm surge, say experts. The National Trust who support volunteers at Horsey Gap issued a statement confirming 263 seals have been lost from the beach. The charities urge visitors to the area not to interfere with the pups to allow the colony to recover naturally. The white coats of young pups are a common sight on the beaches at this time of year. Volunteer group Friends of Horsey Seals monitor the seal population at Horsey Gap nature reserve. The National Trust have as yet been unable to access the national nature reserve at Blakeney Point where they manage common and grey seal colonies, due to "extensive damage" to footpaths and bridges. Female grey seals give birth throughout the autumn months and routinely battle with the elements to raise their young. Experts recommend that the seals are left to recover on their own, so pups separated from their mothers have a chance to reunite without additional stress.
