Rewilding and the weed that ate the South

From Sussex to South Carolina, this week we're exploring what happens when plants take over. What do you get if you mix poor quality farmland, a passion for wildlife and a biodiversity crisis? The answer is a pioneering rewilding project that has stunned ecologists and revolutionised ideas about nature conservation in Britain. We head to Knepp Estate in Sussex to meet Isabella Tree and find out more. Bill Finch is a naturalist who grew up in the Deep South of the USA. Here he witnessed a very different form of rewilding from an invasive plant, kudzu ( Pueraria montana ). It became infamous during the 20th century for swamping roadsides and blanketing everything in its path - becoming known as a scourge and 'the vine that ate the South'. But is it as much of a problem as people think? And finally, podcast regulars Fiona Davison and Gareth Richards discuss the history of two very wild plants, ivy (Hedera helix) and Japanese knotweed ( Reynoutria or Fallopia japonica ).
