Chris Packham and Megan McCubbin have been in each other’s lives since the presenter began a relationship with her mother, Jo, when Megan was just two years old.
The duo became incredibly close and he inspired the young animal-lover to dedicate her career to nature and wildlife.
More than 20 years later, Megan and Chris have co-authored a book and presented numerous TV shows such as Springwatch and Chris and Meg’s Wild Summer.
Opening up to Express.co.uk about their close bond, Megan said: “We’re always there [for each other]. I was on the phone to him about an hour ago and we’re very good friends more than anything else.
Megan also said she was “at the courtroom every day” during Chris’ libel trial.
The naturalist is suing three men over claims he misled people into donating to a tiger rescue charity.
Earlier this month, Chris told the High Court that he had been targeted because of his “deeply held views”, including having “random dead animals and human faeces” regularly posted to him.
In 2021, two masked men set fire to a car outside his driveway which burned down the gate to his house.
Discussing the effect this has on the whole family, Megan explained: “I think with any family member it’s horrible to see what people say and what lengths people will go to. It’s a shame that it got to this point, it didn’t have to.
“It is obviously a worry and we do feel very protective of him and making sure that he’s okay and safe.
“But we’ve got to keep talking about the environmental issues because ultimately, we have to have a healthy environment. I totally respect what he does, what he says, and how he does it.”
It comes as Megan is spreading her own message in her first solo book, An Atlas of Endangered Species.
The volume explores 20 species and details the stories of scientists, rangers and conservationists who are fighting to save the animals from extinction.
On what she hopes readers will take away from reading it, Megan said: “I hope people will connect to the animals and why they’re in trouble.
“But most importantly, I hope they’ll be empowered to do something. I hope they’ll be empowered to use their voice to say what’s wrong and what we’d like to change.”
The book has also been made with dyslexic readers in mind. The font style, colouration and spacing on the page is designed to make it easier to read.
