Donna Nook habitats and species

Donna Nook National Nature Reserve covers more than 10 km (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.

The reserve consists of dunes, slacks and inter-tidal areas. Coastal processes, particularly sand and mud accretion, alter the natural features from year to year, and sand from the beach and offshore sandbanks is blown inland by easterly winds to form dune ridges. Deposition of material from the River Humber has resulted in mudflats and saltings. The advancing dunes have trapped areas of saltmarsh behind them, and these areas have gradually become less saline, allowing an interesting plant community to develop. On the landward side, the reserve is bounded by a sea bank erected after the floods of 1953. The reserve is rich in bird life: 47 species of bird breed regularly and the area is famous for more uncommon passage migrants and rarities; over 250 species have been recorded in total.

There are several access points off the main A1031 coastal road. There are parking facilities at (from north to south): Stonebridge (GR: TF 422998), Howden's Pullover (GR: TF 449952), Sea Lane, Saltfleet (GR: TF 456944) and Saltfleet Haven (GR: TF 467935). Public access is also possible at Merrikin's Pullover (GR: TF 445958), but there are no parking facilities. Access at Howden's Pullover, Saltfleet Haven and Merrikin's Pullover is down unmetalled roads. Visitors should note that the Pyes Hall, Warren Farm, Red Farm and Coastguard Cottage entrances are all private and should not be used.

Visitors should be made 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.

Access for the grey seal colony is at the Stonebridge car park.
