Winter is a tough time for wildlife, but at Lower Moss Wood nature reserve in Cheshire they pull out all the stops to help. Steve Brown meets the volunteers and the inspirational head of the reserve Ray Jackson, who was awarded an MBE for his services to wildlife. Steve is shown the specialist hospital unit where volunteers are busy tending to some poorly hedgehogs. Ray also helps injured bats build up their strength ahead of release in the spring. Steve gets to meet some of the reserve's permanent residents, including foxes tame enough to feed by hand and the owls who wouldn't survive in the wild.Adam Henson launches this year's search for Countryfile's farming hero.
