The crumbling Jurassic Coast in Dorset has already helped us to discover some of the most interesting species from deep time, revolutionising our understanding of dinosaurs and the prehistoric landscape. The latest important fossil to be found along this stretch of coastline is not a huge dinosaur but a tiny mammal. Grant Smith recently found the fossilised teeth of a small rodent like creature which date back to the early Cretaceous period, around 140 million years ago. The sophistication of these teeth have made scientists reassess the time frame for mammal development as they indicate a far more developed mammal species who would have lived alongside the dinosaurs of the Cretaceous period.The new species which Grant unearthed is mankind's earliest ancestor and has been named 'Durlstotherim Newmani', after keen amateur palaeontologist and local landlord Charlie Newman. The landlord of the Square and Compass in Worth Matravers founded his own fossil museum in the pub, and pointed Grant to the location in Durlston Bay at which he found the specimen.The rich history of scientists and academics being ably assisted by passionate amateurs on this coastline is echoed further down the coast at Kimmeridge where Steve Etches, a retired plumber, has just opened his incredible collection of fossils to the public at the Etches Collection. It is a history of collaboration which goes right back to one of the earliest fossil hunters Mary Anning and as Helen Mark discovers the work of the people who live along this coastline in enhancing our understanding of deep time is now being rightly celebrated.

The writer and walker Linda Cracknell joins Helen Mark along North Devon's exposed and rugged coast to seek out the traces of her maritime roots. Her family sailed out of Braunton on the Torridge and Taw. This estuary, which drains large parts of Exmoor and Dartmoor, has the second largest tidal range in the world, and Linda is fascinated by the intertidal zone that's exposed at low tide, a place of wrecks and wader birds. Particularly treacherous is the Bideford Bar, a shifting bank of sand and shingle that sits at the entrance to the estuary, and which has claimed many lives over the years. Helen rows out towards it with the Appledore gig racing team, who love to rise to the challenges the estuary poses. Helen and Linda also meet the Hartnell family who farm Braunton's Great Field, an unenclosed system of narrow strips that dates back past medieval times to the Saxons. Forming the buffer between the sea and the Great Field are Braunton Burrows, a richly varied sand dune habitat, home to orchids and many other rare plants. Botanist Mary Breeds and her husband John, former warden for the Burrows, show Helen and Linda the plants, while Army landrovers rattle by on training exercises. Producer: Mark Smalley.

Helen Mark travels to Sussex to explore the wilderness at Knepp Castle Estate. Isabella Tree and her husband Charlie Burrell have turned their estate which was once intensively farmed over to a rewilding project since 2001. Isabella takes Helen to her favourite part of the landscape which has undergone the greatest change since they started restoring the land back to it's natural and uncultivated state. Helen also goes bird ringing and cattle mustering on the state, now home to long horns, free roaming deer, pigs and Exmoor ponies. She meets a couple who retired and moved to the South Downs for an idyllic country life only to discover the view from their house is more than they bargained for. So is re-wilding the estate really working and should we be doing it? The producer is Peminder Khatkar.

Helen Mark is in Formby in Merseyside, a part of the country that is regarded as a haven for the native red squirrel. She discovers what it is about the landscape and the practices conservationists have adopted, which some find controversial, that's allowing the native reds to thrive in this part of the country. Continuing along the Sefton coastline Helen meets a local resident turned poet; she discovers what makes Formby's sand dunes so special and finds out about the claim that Formby had the first known life boat in existence.Producer: Perminder Khatkar.

Adrian Goldberg travels around Birmingham meeting with fellow Brummies, all of whom have a special vision for the future of Birmingham's landscape. He begins on a huge piece of blank wasteland in the very heart of the city centre which is waiting to become the home of the Birmingham terminal for HS2. He's joined by Waheed Nazir from Birmingham City Council to consider how the anticipation of HS2 is already changing Birmingham's skyline as well the city's sense of its own future.Adrian joins the Birmingham Trees for Life team in a park on the far Eastern rim of the city. The team have coordinated the planting of over 70,000 trees in Birmingham over the past 10 years with many groups of children and volunteers. His next stop is to Britain's first retrofit zero carbon house, just 2 miles out of the city centre in Balsall Heath. Architect John Christophers has a special interest in Sustainable Architecture, and his recently built family home is an inspiring vision of how existing housing stock could be transformed to become carbon neutral homes. When an architectural critic from The Times visited this house he said: "I have seen the future, and it's in Birmingham".Adrian's next visit is to the Apple Day at the Queen Elizabeth Hospital. This is the brain child of HR manager Antony Cobley who has led an initiative to plant orchards and gardens around the hospital grounds for patients and relatives to the hospital.Sutton Park is one of Europe's largest urban parks and is 9 miles to the north of the city centre. Here Adrian joins a group of Rangers and volunteers on a project to transform a dense wood of holly which hasn't been coppiced for over 200 years, to an open woodland of ancient oaks and newly planted rowan trees. Presented by Adrian Goldberg Produced by Rosie Boulton.

The Irish border is currently the focus of intense negotiations around Brexit. Nobody knows how a soft or hard Brexit will work in practise but most agree that a hard border will negatively affect both the economies and relationships of the Republic and Northern Ireland. Helen Mark delves beneath the politics to discover the wildness of the land along the border and talks to the people who live there and cross the border daily. The border has inspired artists and writers such as Garrett Carr and Rita Duffy and Helen meets them to explore the borderlands and try to understand the unique history of the places along the line from Lough Foyle to Carlingford Lough.

Helen Mark meets people whose livelihoods depend on the unique landscape of the Lizard peninsula in Cornwall. She finds rock that looks like snakeskin, otherwise known as serpentine, and hears a dragon breathing. Possibly. It's all a bit reptilian.The Lizard is the most southerly point of England and it's probably not named after serpentine, the snakeskin-like rock that's found here, and nowhere else on earth. It's a peninsula that's almost an island, cut off by the Helford River on one side and the coast on the other, surrounded by some of the cleanest water to be found in the UK. It's kept that way by the rocky coast that makes it dangerous for ships to come too close and muddy up the sea. Salt has been extracted from the seawater here since the Iron Age, and seaweeders still harvest sea spaghetti and pepper dulse from its shores, both for gourmet consumption. Other gourmet items are the organic 'destination pasties' of Gear Farm, which also has an Iron Age heritage to protect in the form of a fort and geophysical evidence of nearly fifty roundhouses which once graced its land. Helen meets Don Taylor, who loves the mystery and magic of serpentine and makes it into sculptures inspired by the shape of the rocks he finds in the cliffs. And there's artist Bridget Leaman, whose home is perched on the cliffs by Lizard village. The landscape here inspires her paintings, sometimes in the most unexpected ways.Producer Mary Ward-Lowery.

Meditation, a celebration, a warning, the marking of a solemn occasion, music: bells are a public sound that changes according to the landscape. And bell-ringing in Devon is unique: it all sounds a bit trance, according to Mary Ward-Lowery. She hears other mind-bending sounds in this programme, including the noisy tramping of ants' feet and the peaceful fusion of bells and birdsong. With artist Marcus Vergette, sound recordist Tony Whitehead, an award-winning band of Devon call-change ringers, oh, and a steeplejack who spends his life mending church towers rocked by centuries of bells swinging the mortar loose.

High Pike in the Lake District is far from the highest peak Sir Chris Bonington has scaled yet from its summit he can see some of the most magnificent views in the Northern Fells and the place he calls home. Helen Mark attempts to keep up with one of the UK's most renowned mountaineers as they climb High Pike together and discovers, not just his incredible story of love and loss but also his passion for the area of Caldbeck itself.

How do you keep history alive? It's claimed the Battle of Pinkie Cleugh - fought in 1547 between the Scots and the English - has largely been forgotten despite being the largest Battle fought on Scottish soil. Helen Mark travels to Musselburgh in East Lothian to see re-enactors gather from across the UK to live as the forces did and fight to the (acted) death to remember the battle in front of an audience. The current Duke of Somerset - who descends from the leader of the English troops braves a return to Scotland to see the event. The areas on which the original battle was fought may not give many clues if it were not for the efforts of the Battlefield Group who fight to protect sites like this and mark their significance in our history.
