32 - 23: Steve & Margherita's Home Patch

Steve Brown explores Elmley Nature Reserve on the Isle of Sheppey, where swallows and swifts are gathering in their hordes, heralding the arrival of summer. Margherita Taylor is on the hunt for an invasive species of moth that threatens not just the oaks on London's Hampstead Heath, but walkers too. On his farm, Adam Henson's horses get their hooves checked and he catches up with trainer Jonjo O'Neill to see how his racehorses are coping with life off the track.
