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.

Thriplow Daffodil Weekend in Cambridgeshire started as a way of raising money for a church roof in 1968. Nearly sixty years later, it is thriving. More than 40,000 bulbs are planted each year to create the incredible displays and a small village of just 250 residents welcomes more than 10,000 visitors over the weekend. Martha Kearney joins them to discover what’s involved, meeting the organiser Paul Earnshaw and ‘daffodil Tom’ who spends his winter planting the bulbs.

Daffodils are ubiquitous in spring in Britain. We see them on vergesides and gardens across the country, but the flower is not native to the UK. Martha visits Cambridge Botanic Garden to find out more about the history and use of the humble daff. There are around 30,000 varieties of daffodil, or narcissus, grown - but some varieties are extremely rare. The Royal Horticultural Society is asking gardeners to log any pink blooms, to find out how many are left.

Celebrated in literature and used for centuries in medicine, there is much more to the daffodil - as Martha finds out on her travels in Cambridgeshire.

Martha Kearney visits Wallasea Island in Essex, the largest manmade coastal nature reserve in Europe. It was created from the 3 million tonnes of London clay that were excavated in the digging out of the Elizabeth Line.

The Stroudwater canal in Gloucestershire was built in the 1770s. It brought coal to the mills along the Stroud valleys, which had become an important centre for the manufacture of woollen cloth, but the arrival of the railways in the mid 19th century led to the canal's decline and eventual abandonment. A mile-long section of it was filled in when the M5 motorway was built in the 1960s, cutting the canal off from the rest of the inland waterways network. Now ambitious multi-million plans are underway to restore and re-open the "missing mile" and reconnect the canal.

Martha Kearney visits the Stroudwater canal to see how the work is going. She talks to volunteers, and finds out what difference the work will make to the canal - as a local amenity, as a tourist attraction and as a wildlife corridor.

Martha Kearney visits the unique cave dwellings at Kinver Edge that were lived in until the 1960s. Cosy cottages were built into the soft red sandstone with windows and doors and families lived in them for generations. Martha looks around a cottage which has been restored as it was when it was lived in and hears about the family that lived there. She also finds out about the heathland restoration project which is bringing rare wildlife back to this valuable sandscape. And she meets Brett Westwood to try and track some of it down.

Hedges are such a traditional part of the British landscape that most of us don't give them a second thought. They're usually associated with the enclosures of the 17th-19th centuries, when the medieval farming system gave way to enclosed fields surrounded by hedges - designed to keep sheep in and people out. But, as Martha Kearney finds out, many hedges are far older than that - going back thousands of years in some cases.

In this programme, Martha explores the history and future of the hedge. She learns that there are an estimated 400,000 miles of hedgerow in Britain, despite the fact that many hedges were grubbed up and destroyed in the years since the Second World War. She talks to a wildlife expert, who explains why hedges are so important for wildlife and outlines the vital role they have to play in the ecosystem.

Martha visits a hedge-laying course in Devon, where trainees are learning this ancient skill, and tries her hand at the craft using a billhook. She discovers that Devon has a hedge style all of its own.

It's an ancient hunting ground with thousands of 'veteran' trees. Henry VIII visited often as it was the seat of the Seymour Family at nearby Wolfhall. Martha visits the forest to learn about its past as well as how ecologist Andy Harris and forester Nikki Morgans manage this special site and aim to 'future proof' it protecting the ancient trees and wildlife for the next thousand years. Historian Graham Bathe helps her measure one of the thousand year old trees and Emma Heard who produces the Weird Wiltshire blog recounts tales of hauntings from the forest.

The Mourne Mountains in County Down are home to Northern Ireland’s highest and most dramatic peaks - a landscape often shrouded in cloud and rain. Yet in recent years thousands of fires have broken out across the range, the majority believed to have been started deliberately. Dry weather and hotter summers linked to climate change have made conditions even more hazardous, alongside the degradation of peat bogs and increased soil erosion.

Martha Kearney visits County Down to hear how local people have been affected, including farmer Sam McConnell and mountain rescue volunteers Neville Watson and Alwynne Shannon. She also discovers what is being done to mitigate the devastation, meeting lead ranger James Fisher and wildfire recovery ranger Linus Voksepp from the National Trust to learn about their vital restoration work.

Have you ever heard of a black poplar? You've probably seen one, at least in a painting, even if you didn't recognise it as such. The black poplar is Britain's most endangered tree, and features in Constable's famous work, The Hay Wain. Martha Kearney is in Suffolk to see black poplars at Flatford Mill, the location in the painting, and to talk to botanical artist Ruth Wharrier about painting from nature. With tree wardens David Appleton and Fe Morris, Martha surveys new trees on the riverbank nearby. She finishes by visiting a new clone bank of trees at Jimmy's Farm, which are thriving between the wolves and polar bears. Without active support, this native British tree could disappear from our countryside altogether.
