Ellie Harrison takes an unflinching look at the state of the country's wildlife - the pressures it is under, the challenges it faces and the prospects for some of the most vulnerable species. Ellie visits Devon to see the efforts being made to save one of the rarest insects, the narrow-headed ant. She also visits the Exmoor estate where water voles haven't been seen in 30 years. Matt Baker is in Cornwall to see how a project to rear lobsters sustainably could have benefits for other threatened sea species. Steve Brown visits a seabird sanctuary still dealing with the after-effects of the Torrey Canyon disaster 50 years ago. And Adam Henson is in Northern Ireland to see how farmers are working with the RSPB to bring back farmland birds
