Martha Kearney explores the shifting sands of Gibraltar Point on the Lincolnshire coast, to witness the effects of beach erosion on both birds and people.
At Gibraltar Point National Nature Reserve, wardens go to extraordinary lengths to protect shore-nesting birds from habitat loss caused by beach erosion. They build wooden platforms for the nests of little terns and cages to protect the nests of ringed plover, as well as mounting overnight patrols to keep predators away. In 2023 they tried the platform technique with oystercatchers for the first time, meticulously moving the nests in stages so as not to spook the birds. The shingle where these striking birds prefer to nest is threatened with inundation from high tides, as well as from foxes, sparrowhawks and curious humans with dogs. The birds raised a successful brood and now the wardens are preparing for another season, hoping for more fledgling oystercatchers.
Reserve wardens aren't the only people to take extraordinary measures to deal with beach erosion. The sand on Lincolnshire's beaches has to be replenished every year to protect the coastal population from flooding. Like sandcastles on an enormous scale, 400,000 cubic metres of sand are pumped onto the beaches from offshore dredgers and a sand profile created, in what's known as 'beach nourishment'. It's become a tourist attraction in its own right. The sand works its way a few miles down the coast to Gibraltar Point with the tides, literally shoring up the sea defences.
And then there are the inland pumping stations at every seaside town, which 'evacuate' water from low-lying areas, of which there are many in Lincolnshire: one third of the county is below sea level. Without them, this landscape would be marshland. Martha compares the historic diesel pumps (made in Lincoln) with the automated electric pumps (from Holland).

Helen Mark is in Dorset to investigate the county's ancient sunken roads, known as holloways. They're deep, steep-sided tracks formed when soft rock erodes and are often overtopped by a canopy of trees. The erosion over centuries creates remarkable, often otherworldly spaces, that come with their own unique flora and fauna. On her trip to the Symondsbury estate near Bridport Helen hears about how the cave spider and goblin's gold moss can thrive in the cracks of these unlikely rockfaces. She is joined by Andy Jefferies and Rosie Cummings from Natural England who are behind a project to map Britain's extensive network of holloways. The holloways often come with their own folklore too. Local storyteller Martin Maudsley recounts the legend of the Dorset colpexie - mischievous sprites that can taunt the unwary traveller!

Jude Piesse moved to Shrewsbury in Shropshire when her job changed, but it was only when she went for a walk alongside the river near her new house that she discovered she was living beside what had once been the garden where Charles Darwin spent his childhood. Much of the original 7 acres of the garden has been built on, but the original house, The Mount, still exists. It has been used as offices for many decades and has only recently been bought and is being renovated with a view to opening it up to the public with a museum and café.
Whilst some local people know about the existence of the house and garden, most people associate Charles Darwin with Down House in Kent where he brought up his own family. Inspired by her discovery, Jude researched the story of the house and garden, learning about the women and the gardeners who were also a part of Darwin's upbrigning.
What becomes clear in this revealing journey is the enormous influence the garden had on a young boy in inspiring his curiosity and fascination with the natural world, which ultimately led to the publication of The Origin of Species.

Martha Kearney hears stories of recovery from the Firth of Forth. First, she takes to the water with guide Maggie Sheddan and skipper John McCarter to explore the iconic Bass Rock, a volcanic island just beyond the shores of North Berwick in East Lothian. A decade ago, Bass Rock became the world’s largest colony of Northern gannets, home to over 75,000 breeding sites. Then, in 2022, Avian Flu hit the colony at the height of the breeding season. By 2023, the total population was estimated at just under 52,000 breeding sites, a decrease of over 30% from the count in 2014. But now, at the beginning of a new breeding season, hope is in the air as the gannets return to the rock.
Meanwhile, back on dry land, another story of recovery unfolds. Over the winter months, North Berwick was hit by huge storms. Four-metre waves, in combination with spring tides, left behind a huge hole in the harbour wall. Martha speaks to Andrew Duns from the North Berwick Harbour Trust and harbour master Ricky Martin about the repairs that are now underway. The storms also shifted the sand dunes on the beaches around North Berwick. Emma Marriott, Conservation Assistant at the Scottish Seabird Centre, tells Martha about the post-storm beach cleans which unearthed ancient litter from the 1960s.

Up until the 1970s, postmen and women in rural areas walked their delivery rounds - taking routes through the hills dubbed "postal paths". Some routes, and fragments of others, still survive today. In this programme Helen Mark explores one of them, near the village of Shap in Cumbria, with author Alan Cleaver who is writing a book about these old paths. So far he's identified over thirty of them up and down the UK. Others have now been built over and are gone forever. Alan tells Helen about the cultural significance of the postal service in the past, recounting the poignant story of a man who used to write letters to himself, just so that the postman would call by and he would have a visitor. Alan and Helen discuss the disappearing role of postmen and women, in the age of electronic communication.
Helen also explores part of Shap's old Corpse Road, which linked Swindale Head with Mardale - a village which didn't have its own cemetery until the mid 18th century. Before that, bodies had to be carried over the fells to Shap for burial - a distance of about eight miles. The last body was carried along the Corpse Road in 1736. Local historian Jean Scott-Smith tells the story of the Corpse Road and shows Helen part of the route.

The Broomway has been dubbed the “deadliest footpath in Britain”, claiming more than a hundred lives. Helen Mark takes a cautious walk along this treacherous Essex seapath with Peter Carr and John Burroughs from the Foulness Island Heritage Centre. She’ll hear how people can easily become disoriented on the vast mud flats and tragically caught out by the rapidly advancing tides of the Thames Estuary. Helen will also be joined by Thea Behrman, the director of the Estuary Festival, to reflect on how this meeting point of land and sea can provide creative inspiration through its bleak beauty.
