Work has begun to assess damage at RSPB reserves in Norfolk following last week's storm.
At Titchwell Marsh reserve, near King's Lynn, the tidal surge smashed the wooden boardwalk out to the beach and the sea flooded into the fresh water marsh.
There was significant damage at the nearby Snettisham reserve.
