What you’re getting yourself into
Tracing the history of sheep from their domestication, to their pivotal role in Medieval British economy, and their unjustified scapegoating at the hands of rewilding experts.
Before we begin, a small scene-setting exercise.
Stand somewhere in the English uplands. It doesn’t matter where. The Pennines, the Brecon Beacons, the North York Moors. Anywhere that involves a reasonable gradient and an implausible quantity of horizontal rain. Look around you at the ancient, green, grazed landscape that the British public has decided is its collective soul: the pastoral ideal, the thing that appears on passports and biscuit tin lids and in the background of every period drama.
Now consider that a not-insignificant number of people, some of them with university degrees and media platforms, would like you to believe this landscape is being destroyed by sheep.
The same landscape the sheep have been shaping for ten thousand years. The landscape whose very name tells you what it is.
Cotswolds. From the Old English cot, a sheep enclosure, and wold, the hills above. A place named, quite literally, for the sheep pens.
We will return to this in some detail. First, though, a short journey to where it all began, approximately eleven thousand years ago, in a part of the world considerably warmer and less given to horizontal rain.
The Mouflon and the Deal
The wild mouflon: a compact, muscular animal with impressive curved horns and a sceptical expression that has been maintained across ten millennia of selective breeding, was not an obvious candidate for partnership with humans. It lived in the rocky highlands of southwestern Asia, across what is now Turkey, Iraq, Syria, and western Iran. It was wary, fast, and extremely good at disappearing into terrain that made hunting difficult.
Sheep and goats were domesticated near the Fertile Crescent approximately ten thousand to eleven thousand years ago, with the earliest evidence for sheep management coming from the village of Aşıklı Höyük in central Turkey, where sheep dating back over eleven thousand years are closely related to wild mouflon ancestors. What began as opportunistic hunting gradually became something more deliberate, more patient, and ultimately more transformative.
The first sheep weren’t kept for wool. That came later, much later: archaeological evidence from statuary found in Iran suggests selection for woolly sheep may have begun around 6000 BC, and the earliest woven wool garments have been dated two to three thousand years after that. Initially, sheep were kept for what every animal offers most immediately: meat, milk, and hides.
But then someone noticed the fleece.
Fine fibres became a valuable commodity and a symbol of prestige, and from that realisation, one of the most consequential industries in human history slowly unspooled. Within a few thousand years, domestic sheep had spread from their highland origins across the entirety of the known world. By 7,000 years ago, they had reached Europe. By 5,000 years ago, they were established across much of Asia and North Africa.
Pastoral nomadism became possible, entire communities following their flocks across vast landscapes, utilising grazing land that was unsuitable for crop agriculture. Sheep became central to religious practices, social structures, and economic systems. They appear in every major religious text. They appear in the heraldry of dozens of nations. They appear in the stained glass windows of churches you will shortly learn were built, in no small part, from their proceeds.
One of the more remarkable genetic footnotes in this story involves what the sheep did for human clothing, and what human clothing did for human geography. Researchers believe that the development of woollen clothing encouraged humans to live in areas far colder than the Fertile Crescent, where temperatures averaged 21°C. The sheep, in other words, didn’t just feed the early Neolithic. It expanded the entire habitable world.
Why The Sheep Works Where Nothing Else Can
The sheep’s dominance across the British uplands isn’t an accident of history or a consequence of misguided agricultural subsidies. It is the animal doing exactly what it evolved to do, on land that offers very few other options.
The key is the rumen: the same four-chambered fermentation system that makes the goat such a formidable converter of marginal vegetation, applied here to a creature that has been specifically shaped, over millennia, for the cold, wet, windswept hillsides of northern Europe.
Like all ruminants, the sheep operates a biological processing plant in its first stomach. The rumen is effectively a large fermentation vat, containing billions of bacteria, protozoa, yeasts and other species that can digest the fibre. They proliferate, releasing useful nutrients for the cow, sheep or goat, and when they die provide additional protein.
This is the mechanism by which the sheep takes the coarse, nutrient-sparse grasses of the Pennine fellside and turns them into complete animal protein, B vitamins, fat, and eventually the milk that becomes Wensleydale. The grass does not have to be good. It does not have to be particularly digestible. The rumen will sort it out.
Cattle, sheep and goats have the ability to convert plant carbohydrates and proteins into available nutrients for human use, making otherwise unusable land productive. The word ‘otherwise’ is doing significant work in that sentence. Without the ruminant, a large proportion of the British land mass contributes nothing to the food system. It just gets wet.
British sheep breeds have been developed over centuries specifically for the resilience required to survive in conditions that would defeat a more sensible animal. The Herdwick of the Lake District, unchanged in essential character since the Norse settlers brought it to Cumbria, has a fleece so dense it can shed water in conditions that would give hypothermia pause. When a Herdwick ewe is buried in a snowdrift for weeks and emerges alive, having survived by eating her own wool, this is not a curiosity: it is the animal doing exactly what it was bred to do.
The Soay, a primitive breed now confined to the Scottish islands, is genetically barely distinguishable from the earliest domesticated sheep. It requires no veterinary care, no supplemental feeding, no human intervention of any kind. It has been on the islands of St Kilda for at least two thousand years. The St Kildans, who were evacuated from their islands in 1930, relied on Soay sheep and seabirds as their primary nutrition sources for millennia. The sheep managed itself. The sheep still manages itself.
There are hundreds of distinct British sheep breeds, each adapted to the specific demands of a particular landscape. This is not redundancy. It is the accumulated result of ten thousand years of practical trial and error, breeding for resilience in conditions that vary enormously between a Suffolk lowland and a Scottish hillside. You don’t replace that with a rewilding grant application.
The Golden Fleece: How A Sheep Built A Cathedral
The Cotswolds in high summer is an almost aggressively picturesque place. Honey-coloured stone walls, rolling limestone hills, villages that seem to have been assembled specifically for the purpose of being photographed. It is the background of half the British tourism industry, the shorthand for “traditional England” deployed in everything from heritage television to chocolate boxes.
It is also, in its current form, a monument to sheep.
The Romans introduced sheep with exceptionally long fleeces into the Cotswolds. These sheep defined the way of life of this area for 2,000 years. Even the name Cotswolds is thought to come from “cots” meaning sheep enclosure and “wolds” meaning the hillocks of the area. The landscape itself is named for the animal. The villages are named for it. The wool churches are built from its proceeds.
By the end of the 12th century, the Cotswold wool trade was already an international enterprise. In 1297, the English barons declared that wool amounted to half the wealth of England itself, while in parliament in 1353, wool was described as ‘the sovereign merchandise and jewel of [Edward III’s] realm of England’. Edward III was not given to flights of rhetorical excess. He also commanded that the Lord Chancellor, when in council, should sit on a wool bale: the Woolsack, a tradition that endures in the House of Lords to this day.
There is a certain quiet satisfaction in the knowledge that British parliamentary authority has been ceremonially seated upon a sheep product for the better part of seven hundred years, while the people who actually keep sheep are told their animals are destroying the environment.
But the cathedrals. We should talk about the cathedrals.
A wool church is an English church financed primarily by donations from rich merchants and farmers who had benefited from the medieval wool trade, hoping to ensure a place in heaven due to their largesse. Wool churches are common in the Cotswolds and in the “wool towns” of upland East Anglia, where enormous profits from the wool business spurred construction of ever-grander edifices.
These are not modest village churches. They are, in several cases, among the finest examples of perpendicular Gothic architecture in England, built between the 14th and 16th centuries and rivalling small cathedrals in their scale and splendour. Built between the 14th and 16th centuries, these churches rival small cathedrals in their size and splendor, showcasing the finest examples of Perpendicular Gothic architecture.
Walk the floors of St Peter and St Paul in Northleach, and you will find the brass woolmarks of merchants pressed into the stone: their professional identity, their permanent signature on a building their animal’s back paid for. One brass from the mid-1400s shows John Fortey, who bequeathed £300 for the complete restoration of the church, standing with one foot on a sheep and the other on a woolpack. The man knew where his money came from.
Legislation was introduced in the Stuart period to keep domestic wool consumption high, including the rather macabre Burial in Wool Acts, which stated that all bodies had to be buried wearing woollen clothes, apparently the origin of the phrase ‘to pull the wool over someone’s eyes’.
Your idioms, your parliament, your medieval architecture, your landscape. All of it, sheep-adjacent.
In 1193, Cistercian monks are said to have provided fifty thousand sacks of wool towards the ransom of Richard I, who had carelessly allowed himself to be captured returning from the Third Crusade. Whether or not the figure is accurate, the sentiment is revealing: the sheep was already, by the High Middle Ages, the most reliable store of negotiable wealth in the country. The animal didn’t just feed Britain. It financed it.
The Rewilding Argument and What It Gets Wrong
There is a version of the rewilding critique that is reasonable. Overgrazing is real. Headage-based subsidies that paid farmers for the number of animals kept, rather than the quality of land management, created genuine problems in some upland areas during the latter half of the twentieth century. Overgrazing encouraged by headage-based subsidy payments resulted in dramatic declines in habitats of international conservation significance.
This is true. It is also historical. Those payment structures changed. The landscape changed with them.
The unreasonable version of the rewilding argument is the one that treats this historical overgrazing as an indictment of sheep themselves, rather than of a policy framework that has since been largely dismantled. This version proceeds from the assumption that British uplands would be better without any sheep at all, and that the presence of the animal is itself the problem.
It is simply incorrect to blame sheep, or upland farming more broadly, as the root cause of environmental decline. Site condition in designated protected areas is influenced by a multitude of factors, and reducing grazing levels alone, a strategy driven by environmental schemes over the last 20 years, has not yielded the improvements of ecological recovery many expected. In fact, evidence shows that inadequate grazing, whether from sheep, cattle or ponies, has often allowed damaging encroachment by bracken, gorse and purple moor grass, degrading biodiversity and habitat quality.
This is the part that gets left out of the influencer version of the argument. Remove the sheep, and you don’t get the romanticised wilderness of the rewilding imagination. You get bracken. You get purple moor grass. You get gorse advancing across former flower-rich meadows with the relentless indifference of a slow-motion natural disaster.
Removing grazing, as rewilding would do, benefits the diversity of important groups like birds, moths and spiders. However, the diversity of groups such as plants and beetles, as well as the population of a key upland bird species, the meadow pipit, benefit from the disturbance brought about by heavy grazing. Only through assessing both the “winners” and “losers” from land use change can we develop appropriate regional or national strategies for land management.
No scenario benefits every species. This is inconvenient for anyone with a simple narrative to push, but it happens to be what the long-term research actually shows.
The appropriate grazing of British uplands at the right intensity is not an enemy of biodiversity. It is, in many cases, what creates and maintains it. The patchwork of short grass and bare soil and scrub that produces the habitat mosaic for wading birds, rare plants, and invertebrates is not produced by absence. It is produced by management. Often, by sheep.
Appropriate grazing at the right intensity and with the right species remains essential to managing and maintaining the mosaic of habitats valued by ecologists, land managers and local communities alike.
The sheep-free vision of the British uplands is not a vision of nature recovering. It is a vision of one kind of nature replacing another, presented as unambiguous ecological progress, in the absence of anything resembling honest accounting.
Land Salmon: What The Nutritional Data Actually Says
Here is where the sheep quietly destroys its competition, and where the absence of the animal from British plates becomes particularly costly.
All sheep are, by default, grass-finished. This is not a premium designation requiring a special label or a price uplift at the butcher. This is just what sheep are and how they live. A sheep grazing the moors above Skipton is not being given grain. It is eating the grass and herbs that have been growing in that valley since before English was a language. Its body composition reflects this.
When ruminants are raised on fresh pasture alone, their products contain from 300 to 500% more conjugated linoleic acid (CLA) than products from animals fed conventional diets. CLA is the fatty acid formed when plants are fermented in the ruminant stomach, and it has anti-cancer, anti-obesity, and anti-diabetic properties that are increasingly well-supported in the research literature.
Beef, by contrast, in most commercial settings, is not grass-finished. It starts on pasture and ends in a feedlot, where the omega-3 profile it built during its months on grass is progressively dismantled by a diet of grain. You can pay considerably more for grass-finished beef and get back some of what was lost. Or you can buy lamb and not have to think about it.
Lamb, all lamb, has the healthiest omega-6 to omega-3 ratio of all domestic land animals. Not grassfed lamb. Not premium label lamb. Just lamb. The omega-3 content is higher than beef across the board, including grassfed beef, and the ratio approaches that of salmon closely enough that the term “land salmon” has been coined and is not entirely irresponsible.
Grass-fed lamb is more nutritious than conventionally raised, grain-fed beef, as it contains healthier types of fat, more micronutrients and antioxidants, and it is also better for the animal and the environment.
The selenium content of lamb is notable. The CLA content is higher than any other domestic meat. The iron is heme iron, the absorbable form. The B12 is abundant. The zinc is comparable to beef. And all of this is available in every lamb you buy, regardless of price point, because every lamb has been eating grass. The default setting of the animal is nutritional excellence.
Sheep Milk and the Dairy Nobody Bothers With
If lamb is the most underrated meat in the British diet, sheep milk is the most underrated dairy product in the known world.
The concentrations of butyric acid, conjugated linoleic acid (CLA) and omega-3 fatty acids are remarkably higher in sheep milk than in milk of other ruminant species. Sheep milk contains nearly twice as much protein as goat and cow milk.
Twice the protein. Higher CLA. Superior omega-3 profile. And more calcium, too — sheep milk contains approximately 36% more calcium than cow milk and 31% more than goat milk. The B12 content is roughly three times that of cow milk. The fat content is higher, but it’s the right kind of fat: medium chain triglycerides, smaller fat globules, more readily converted to energy and less prone to storage than long-chain alternatives.
Sheep milk’s protein is more readily digested and its fats are more readily converted into energy compared to cow milk. A clinical trial confirmed this is not merely anecdote: sheep milk produced less hydrogen gas in breath tests, a marker of malabsorption, and caused fewer digestive symptoms despite being nutritionally denser.
This is the dairy product that produced Roquefort, pecorino, manchego, and feta: cheeses that have dominated the fine dairy traditions of Europe for centuries. The shepherds of Bulgaria, who were famous for extraordinary longevity, credited their consumption of sheep milk products as a significant factor. This may be folklorism, but it is folklorism with a nutritional data set behind it.
In Britain, sheep milk remains almost entirely niche. You will find it in specialist shops and farmer’s markets, occasionally in health food sections, usually at a price that reflects the smaller scale of production relative to the dairy behemoth that is cow milk.
This is, frankly, a waste.
The Animal That Refuses to Go Away
There is something instructive about the persistence of the sheep across the entirety of British history. The Romans brought improved breeds. The Normans intensified the trade. The monasteries became some of the most sophisticated wool-producing enterprises in medieval Europe. The Black Death killed half the population and the sheep simply filled in the labour gap: one man could look after 500 animals, the medieval equivalent of automation. Between 1280 and 1365, wool exports doubled, mid-plague.
The industrial revolution arrived. The wool trade shifted to mechanised mills. The sheep remained on the hills, producing meat and milk and wool for a new kind of economy.
Subsidies came and went. Policy frameworks changed. Some sheep farmers grazed too hard; most didn’t. The landscape continued to be managed, with all the complexity and contradiction that implies. And through it all, the sheep was there, on the hillside, converting grass that nobody else could use into food that people needed.
Now the rewilding movement would like them moved along. The influencers have decided that the ancient pastoral landscape is, actually, an ecological disaster. The academics write papers about bracken colonisation and upland biodiversity deficits, which are not wrong exactly, but which tend to omit the question of what happens to the uplands: ecologically, nutritionally, economically, when you take the sheep out of them.
What happens is bracken. What happens is gorse. What happens is the loss of the flower-rich meadows that depend on managed grazing for their existence. What happens is imported lamb from the other side of the world to fill the gap in the food supply, with all the carbon accounting that entails, while British hillsides are left to scrub up behind a rewilding press release.
The sheep does not need defending, particularly. It has survived the fall of Rome, the Black Death, the Highland Clearances, and six hundred years of being sat upon by the Lord Chancellor. It will survive this too.
But it might be worth, every so often, looking at what is actually standing on those hillsides and asking what exactly it is that you’re looking at.
An animal that has been converting inedible landscape into food, fibre, and economic wealth for eleven thousand years. An animal whose rumen contains an ecosystem more complex than most people’s understanding of ecology. An animal whose milk outperforms cow milk across almost every nutritional metric that matters. An animal whose meat comes pre-finished on grass, pre-loaded with omega-3, pre-saturated with CLA, without anyone having to pay extra or read a label.
An animal whose hoofprints are pressed into the foundations of the churches you walk past and the parliament you’re taxed by and the landscape you photograph when you want to show someone what England looks like.
Half the wealth of England rides on the sheep’s back. That’s not marketing copy. That’s what the medieval barons told Edward III in 1297.
They weren’t wrong then.
They’re not wrong now.
