Iolo was left terrified as he had to walk a mile back to his car and phone after suffering a heart attack while in the middle of the countryside last year.
Michaela said: 'The theme of Winterwatch is resilience and renewal – only the tough survive and spring brings warmth and renewal.
'Last year was a tough year for people. So Winterwatch will bring some joy.”
It comes after Iolo told of the terrifying mile-and-a-half walk back to his car and phone after suffering a heart attack in the middle of the countryside.
The presenter became ill and developed pain in his chest while he was alone and had no one around to help.
Iolo said he returned to his vehicle and paused when the pain became too much before calling emergency services upon arrival.
He told the Mirror: 'It came like a bolt from the blue. I knew what it was: intense pain under my breastbone. It was a heart attack. And I thought, well, I can't get down here!
'So I kept walking, squatting a bit every now and then when the pain got a bit worse.
'I walked to my car, called an ambulance and they said it would take about 90 minutes.
The presenter, 61, will join (pictured L-R) Michaela Strachan, Gillian Burke and Chris Packham at the RSPB Arne in Dorset to film four nights of live shows capturing wildlife.
Iolo stopped filming on his nature television program after suffering an 'unexpected' heart attack and major complications following his surgery to place a stent in an artery
'So my wife, Ceri, came down, took me to hospital and from then on I was in the hands of the NHS. They were excellent.'
In October, it was reported that Iolo withdrew from his television filming duties after suffering an “unexpected” heart attack.
He suffered serious complications after his operation to place a stent in an artery.
The treatment involves inserting a short wire mesh tube that acts as a scaffold, called a stent, to widen and open narrowed or blocked arteries that supply the heart muscle.
According to the NHS, the procedure carries risks such as damage to arteries, allergic reactions and excessive bleeding.
