A CONSERVATION charity has counted a record number of grey seals at their South Walney Nature Reserve, thanks to the latest drone technology.

Cumbria Wildlife Trust’s recent drone survey counted 483 seals at the reserve which shows a 35 per cent increase since the last one.

South Walney Nature Reserve is a haven for many species, from the large numbers of lesser black-backed and herring gulls to the multitude of waders and since the 1990s the grey seal colony has been increasing.

Sarah Dalrymple, Warden at South Walney Nature Reserve, said: “This is very encouraging news indeed – we’re delighted to see that the grey seal colony at South Walney continues to thrive," she said.

“We go to great lengths not to disturb the colony and to ensure that all visitors to our reserve are equally respectful of these wonderful marine mammals.

"The seals are extremely vulnerable to disturbance and we can put this record number of seals down to the fact that our strong and consistent ‘do not disturb’ message is really getting across to the public.”

The previous drone survey which was again the highest was done in January 2018 when 360 seals were counted.

Strict measures mean that the drone has to be very high so as not to disturb the seals below and required special permission from Natural England.

This is also the second year that drone technology has been used to help monitor the colony.

Sarah said: "It’s a great resource for us to use, although we’re continuing with our traditional counts, which involve crawling across the shingle and watching the seals through binoculars, to compare results.

"Both methods are important, but the drone gives us more accurate numbers."

Seal surveys are carried out fortnightly at South Walney Nature Reserve, from September to March. The surveys monitor the seal population structure in the area from year to year.

The behaviours displayed by the seals are also monitored to gain an understanding of how they respond to different factors. This includes how they are affected by human disturbance, such as boating and recreational use of the sea surrounding Walney Island.

This season seven seal pups were recorded at South Walney Nature Reserve. There is strictly no access to the area of the nature reserve where the seal pups are.

However, the rest of the seals can be seen playing and fishing in the water at high tide, along with thousands of wintering wildfowl and wader birds, from hides elsewhere on the nature reserve. You can the observe the seals online at: www.cumbriawildlifetrust.org.uk/wildlife/cams/seal-cam
