Martha Kearney meets the people protecting and restoring rare arctic-alpine plants in Eryri, also know as Snowdonia. Robbie Blackhall-Miles is a conservation horticulturist working for the charity Plantlife. He shows Martha his secret nursery for rare plants where he's been propagating species such as the previously extinct rosy saxifrage, in preparation for reintroducing them to the mountains.

Martha and Robbie travel to the valley of Nant Ffrancon where work has been happening in collaboration with farmers to change grazing practices, in order to help the arctic-alpine plants survive. This work has been happening as a part of the Tlysau Mynydd Eryri / Mountain Jewels of Eryri project, which is part of the wider National Heritage Lottery funded Natur am Byth (meaning Nature Forever) partnership project. We hear how the National Trust will be expanding Robbie's work in reconnecting habitats in their new Natur i Bobl Nant Ffrancon project (meaning ‘Nature for the people of Nant Ffrancon’).

Between the mainland and the Isle of Wight, when the tides are low enough and the days long enough, a sandbank emerges from the Solent. At some point each summer, in most summers since 1984, this exposed bank becomes the venue for an extraordinary event: a cricket match between two sailing club teams from opposite sides of the Solent.

Test Match Special commentator Alison Mitchell joins the team setting off from Hamble, near Southampton, to witness this remarkable contest, which can only take place on a low-water spring tide. She talks to players including former England cricketer Norman Cowans and his teammate Sir Robin Knox-Johnston, the first person to sail single handed and non-stop around the world

Arriving at Bramble Bank by boat at dawn, she follows and commentates on the action as it unfolds, before departing as the tide returns and the pitch disappears beneath the water once again.

Pilgrimages are usually associated with the Middle Ages, when they were at their peak. Banned by Henry VIII in the 16th century, they are now regaining popularity. In this programme, Martha Kearney joins a group of people on a river pilgrimage in Kent. They're spending ten days walking the entire route of the River Medway, from its source in the High Weald in Sussex to the point where it empties into the Thames estuary - seventy miles in all. The aim is partly to highlight the current plight of the river, and to spend time monitoring pollution levels, clearing away litter and learning about its importance in the landscape. Martha meets the Director of the Friends of the River Medway who explains about the river's environmental state and its cultural significance. She also talks to the founder of the British Pilgrimage Trust and finds out why people are being drawn to pilgrimages in the 21st century, learning that they are not necessarily religious, but more a case of "bring your own beliefs".

Martha Kearney learns ancient skills like forging a knife, flint knapping and making a fire with flint and steel, alongside local schoolchildren at the Ancient Technology Centre in the Dorset countryside. The centre is a unique collection of archaeologically accurate reconstructions of ancient buildings, used for hands-on outdoor history education. Each building represents a different time period: there’s an Earthouse, a Roman forge, an Iron Age Roundhouse, a Saxon workshop and a Viking Longhouse.

When Donald Campbell died on Coniston Water in Cumbria in January 1967, attempting to break his own water speed record it was, to many people, the end of an era. Many would always remember where they were when the images of Bluebird K7, the jet hydroplane he was piloting, crashing and disintegrating on the lake appeared on TV screens and the story broke across the world.

In March 2001, after 34 years underwater, Donald Campbell’s ill-fated craft was raised from the deep by wreck-finder and engineer, Bill Smith. Later that year, at the request of Donald’s daughter Gina, his remains were also recovered - and in September 2001 he was finally laid to rest in the churchyard at Coniston. A painstaking restoration project began and in 2026, over 20 years after she was raised from the depths, Bluebird is set to finally return to Coniston Water.

Caz Graham visits Coniston Water to discover what Bluebird means to the Lake District as she returns to the water 70 years after Donald Campbell set the water speed record in 1956.

Martha Kearney is in Norfolk to walk the heathland that is being returned to its ancient grassland habitat by Olly Birkbeck. The Society of Wildlife Artists is holding a year-long residency documenting the recovery of the land and the flora and fauna.

Britain's roadside verges rarely get much attention, but can play host to a whole range of plant and animal species. In this programme Martha Kearney finds out about this overlooked habitat. She meets a community group in East Sussex whose members grow plants at home specially to plant in the verges of their village, and talks to the charity Plantlife about the importance of verges as an environmental habitat. She goes out exploring with artist Nessie Ramm, who focuses on painting the tiny details of roadside verges, and who last year won the New English Art Club Climate Emergency prize for her work entitled 'Reduce Speed Now'.

Jon Gower is in Criccieth in Gwynedd, to explore the area’s connection to Robert Graves’s 1929 poem, Welsh Incident.

Robert Graves wrote the poem after inspiration struck on his train travels in the area with his father, after a Welsh policeman aboard told them a story of having recently seeing a mermaid from the sea caves of Criccieth.

Jon Gower, a writer and poet himself, heads to the source to learn more, hearing about how the poem resonates with current local residents like the clerk of Criccieth Town Council, Catrin Jones, who then commissioned Howard Bowcott, a local artist, to make a playful sculptural interpretation of the poem for the town green.

Britain’s deer population has surged to around two million. These iconic animals are well-loved, but their growing numbers are putting real pressure on the countryside - stripping young hedges and woodlands, damaging crops, preventing natural restoration and harming other native wildlife. To control the population, hundreds of thousands of deer are shot each year. Critics argue hunting in the name of conservation is inhumane, and a short-term fix. Others baulk at eating ‘Bambi’. Supporters argue that it’s the most sustainable, environmentally-friendly meat you can get. Mary-Ann Ochota heads into the field with a professional stalker to see what deer management really involves, from woodland to wild meat.

Martha Kearney visits one of the UK’s earliest environmental restoration projects. Southern Scotland was once covered in broadleaf woodland, rich scrub, heath and bog. That was before sheep, humans and conifers took hold. Now a group of visionary volunteers are restoring that landscape in what they call the ‘wild heart of southern Scotland’.

Set in a 1600 acre glacial valley in lowland Scotland, Carrifran Wildwood is the first tranche of a wider restoration area which aims to wheel back six thousand years. The idea is to recreate the primeval forest that proliferated back then. It will act as a carbon sink, a flood mitigator and a generator of biodiversity.

The planting schedule is drawn from a catalogue created from evidence in the ancient peat bog. Unlike other ‘rewilding’ projects, Carrifran Wildwood aims to exclude human beings from this valuable space, an unusual step which the founders see as crucial to its success.
