Joe Crowley and Charlotte Smith are in the Highlands, visiting a 100-acre rewilding site near Loch Ness known as the Natural Capital Laboratory. But this is no ordinary lab, and there's not a white coat in sight. Instead - and with the help of the latest technology - scientists here are mapping, tracking and quantifying the changes to the landscape and the life in it. Charlotte looks at hi-tech devices that track animals and create a virtual vision of what the site will look like in 100 years' time. Joe digs in, discovering how efforts to restore neglected peat bogs could pay dividends for the environment. Tom Heap investigates the impact that reintroducing long-lost species could have on our countryside and its people, and wildlife film-maker Tom Hartwell take us on a journey into the beautiful and brutal life of the cinnabar moth.
