Sean Fletcher and Matt Baker head to the Usk Valley within Bannau Brycheiniog, formerly referred to as the Brecon Beacons. Bannau Brycheiniog is more than a name. It signifies a wider change that is happening to the whole management of the national park. Sean and Matt look at a series of projects and initiatives that are under way, all aiming to restore nature, balance the needs of the people who live, work, and visit the area, whilst ultimately leading Bannau Brycheiniog into a more sustainable future. Not everyone, however, has welcomed the change. Sean meets local businesses to find out their reaction, and he also discovers an ambitious plan to feed the 33,000 residents by food that is all produced in the park. Matt heads into the hills to tackle a problem plant and explore how a restoration project is changing this nature-depleted landscape.
