Pupping season for gray seals on a seashore in Norfolk has seen births go from fewer than 100 to round 2,500 in 20 years.
This yr’s depend was referred to as off as a result of excessive tides which pressured the animals on high of the dunes at Horsey Hole, making it too harmful for volunteers to achieve a totally correct determine.
However Peter Ansell, chairman of Associates of Horsey Seals, mentioned he would make an “educated guess” {that a} minimal of two,500 gray seal pups had been born since November.
He mentioned there had been a ten per cent improve annually, telling the PA information company: “It’s a bit just like the human inhabitants, actually.
“The older ones live longer so that they’re not dying off so fast, and the youthful ones are reproducing at a fast price, and yearly you’ve acquired a contemporary batch of recent moms coming alongside, along with all of the established ones.”
The seals are born on a stretch of seashore between Waxham and Winterton.
Mr Ansell mentioned that if extra-high tides proceed to occur then future counts might also need to be referred to as off.
“This in all probability will occur once more subsequent yr, as a result of if we’re going to proceed to get these extra-high tides then the seals will do what they’ve performed this yr – they’ll go for the excessive floor and we could discover it unattainable in future to do the counts.
“However we’re speaking about nature right here, and with nature you’ve no concept what’s going to occur subsequent week, by no means thoughts subsequent yr.”
Mr Ansell recalled a surge tide in about 2013 which was “like a mini-tsunami”, including: “We misplaced about half the pups that have been on the seashore at the moment.”
He mentioned there have been about 600 in whole that yr and 300 have been misplaced.
“They have been swept out to sea and that was it,” he mentioned.
Mr Ansell mentioned there are many open seashores additional down the coast and there’s a chance the seals could migrate a bit bit north or south.
“I actually can’t forecast with any accuracy what’s going to occur subsequent yr,” he added.
“For the time being it at the moment has expanded from a really, very tiny strip of seashore… in say 2002/2003 there have been lower than 100 seals on the seashore.
“There have been a lot lower than 100 pups born. And from there it’s gone from 50 or 60 pups… in 20 years it’s gone as much as 2,500.
“That offers you an concept the way in which they’ve been growing.”
