The team travel to Exmoor. Matt Baker meets a group of youngsters on the National Citizen Service scheme, a residential course that uses outdoor activities to help children from all backgrounds to build skills for work and life. Exmoor is one of only a handful of places in the country where the UK's most endangered butterfly - the high brown fritillary - can be spotted, and Margherita Taylor meets those doing all they can to restore its habitat in a bid to increase its numbers. This involves using a remote-controlled mini-tractor that breaks down bracken to create runnels that the butterflies can travel though. It also encourages the underlying violets to grow that the caterpillars feed on. Adam Henson meets the Sikh family of strawberry-growers that are uniting farmers around Worcestershire, who have started the Growers United Football Charity. It not only brings local farmers and growers together and raises money, but also promotes agriculture as a key sector of the economy. Tom looks at what is being done to fight lyme disease, a debilitating illness that affects up to 3,000 people a year and is often transmitted through a single bite from an infected tick. Joe finds out how moorland communities are dealing with the impact of this summer's wildfires, looking at how the continuing dry spell is forcing farmers to use up vital supplies of winter fodder to make up for the lack of grazing in the parched countryside. The Young Presenter Talent Search reaches its climax, as Anita is joined by fellow presenters Nick Baker and JB Gill to decide the winners in each age category.
