Following on from Episode 15 Jo and Cathy make a return to the peatlands, this time to a lowland raised bog on the outskirts of Manchester and Salford. Little Woolden Moss formed over thousands of years but was almost totally destroyed in the 1990s by peat extraction – it became a barren, lifeless place, swirling with clouds of black dust. Jo and Cathy meet Jenny Bennion from the local Wildlife Trust and Dave Steel, a birdwatcher and bog volunteer, to find out how it's now being brought back to life and becoming a wildlife haven once again.
