The 100 Mile Wildlife Corridor

Martha Kearney follows the River Ouse, from the High Weald to the Sussex coast and - finally - into the sea itself. Along the way, she discovers how one of the UK's largest nature recovery projects is taking root.

The project is called 'Weald to Waves' - it's a wildlife corridor that has been mapped out over more than 100 miles of Sussex landscape and coastline, to encourage biodiversity on a huge scale, connecting food, farming, nature and people. Encompassing more than 20,000 hectares of contiguous habitat, it is a huge coming-together of farmers, land managers, councils, utility companies, wildlife charities, schools, gardeners and community groups. Martha meets some of the people who have pledged to be a part of this huge collaborative effort.
