Weekly seal update
Weekly seal update from Donna Nook
This page is updated once a week, usually on a Friday, between late October and early January, with a seal count from our Warden at Donna Nook.
The scene from the viewing area in late January.
2,066 grey seal pups were born last year at Donna Nook. They are now out in the North Sea.
We'll start regular updates here when the pupping season begins again in late October.

The first seal pup has been born at Donna Nook. This one is a little further out from the viewing area so an extra part of the dune has been roped off so the pup can be seen from a safe distance. Don't worry, there will be hundreds more in November, so don’t all rush down to see this one!

By 19 December about 75% of the seals had left. The high tides that week left lots of pools on the saltmarsh and the pups had a great time splashing about. By New Years Day there was just 1 bull, 1 cow and 8 pups seen from viewing area.

The first Dunes pup was born on 23 October 2013. Pup numbers peaked with the count on 29 November when there were 1,528 pups. The last pup was born on 18 December. The total number of pups born was a record 1,676 and the surge is not expected to have a long term impact on the seal colony.
The season was dominated by the meteorologically-induced tidal surge which combined with the already high spring tide of 5 December, causing widespread damage and disruption to both the seals and site infrastructure. The surge added approximately 2m to the predicted tide height and reached well into the dunes beyond the double fence. Gates in the fence were opened to allow seals to reach the safety of the dunes and further gaps had to be cut as the water level rose and wave action increased.
The seals were severely disrupted but there is little evidence of widespread mortality.
The seals at Donna Nook are counted once a week and it is impossible to say how many of the adult and pups had returned to sea at the time of the surge. In many cases cows were able to stay with their pups, despite being displaced all along the coastline. Regular monitoring was maintained for several weeks following the surge tide, with 37 pups being taken to Mablethorpe Seal Sanctuary for care before their release, and others being captured and released on the beach, or left to find their own way out to sea as appropriate.
