A recent survey, which is considered the most comprehensive one conducted by Zoological Society of London (ZSL) has revealed that there are about 708 seals in the Thames Estuary. Volunteers and conservationists took part and surveyed solid ground and the river to count grey and harbour seals.

The survey was conducted to help conservationists properly determine the size of the seals’ population so they’ll know the best way to monitor and protect them.

The survey was conducted in time for the annual seal moult. This is the time of the year when seals shuffle onto sandbanks where they’ll shed their coat. This made it easier for volunteers to count them.

Stephen Mowat, ZSL’s Thames Projects Manager, said: “The harbour seal population in south-east England is the least understood in the country.

“As well as the survey, we are urging members of the public to report sighting of seals and other marine mammals to us.”
