Sixty
years ago the Thames Estuary was regarded as "biologically dead" and
largely devoid of wildlife.
But,
in recent years seals have returned to the Thames as well as to the coastal and
low-lying lands bordering the estuary.
Last
year, scientists recorded more than 3,500 harbour and grey seals.
Now,
they are starting the first count of seal pups to see how important the area is
a breeding ground.
"These
seals are higher predators in the estuary," says Thea Cox, conservation
biologist at the Zoological Society of London.
"Knowing
how many there are is a really good indicator of the health of the estuary,
what habitat is available to them, what food source is available to them."
