Seals and pups captured by photographer Lisa Harding at Donna Nook Military Range in Saltfleet, Lincolnshire, for the annual arrivals.
Donna Nook covers more than 10km (6.25 miles) of coastline between Grainthorpe Haven in the north and Saltfleet in the south where it borders the Saltfleetby-Theddlethorpe National Nature Reserve. Every November and December, grey seals come to the Donna Nook coastline to give birth to their pups near the sand dunes; a wildlife spectacle which attracts visitors from across the UK.
Visitors should be aware that the Ministry of Defence still maintains part of the area as a bombing target range and under no circumstances should anyone enter the bombing area when red flags are flying. However, most of the dune area is accessible at all times.
