Ellie interviewed Lancashire Wildlife Trust's Mark Champion and Sue Lonsdale and Edge Hill Biology student Holly Bryce (below), who is currently in the midst of her dissertation.
Mark said: "I cannot reveal exactly why Countryfile were here. That is a surprise, but they were a lovely, friendly bunch and the braved extremes of Wigan weather with a sunny start followed by torrential rain. They also tasted local delicacies by having a pie for lunch.
"Getting Countryfile here gives everyone a lift and it helps us to publicise the work we do. Our work in Wigan is vital to local wildlife."
