As one of the world’s purest and oldest sheep breeds, Icelandic sheep are strong and sturdy animals with beautiful, thick coats. Long-used in Iceland for their meat and wool, the sheep that exist in Iceland today are direct descendants of the sheep brought to Iceland by early Viking settlers.

With around 500,000 sheep and only around 370,000 humans, there are more sheep than people living in Iceland. So, what exactly is so interesting and special about the Icelandic sheep? Let’s explore some of the history and interesting facts about this breed below.

10 interesting facts about Icelandic sheep:

  1. Most sheep are white, but some are black, grey or brown.
  2. It is forbidden to import any other sheep breed to Iceland, making Iceland's sheep the only breed you’ll find in the country.
  3. Icelandic sheep have remained genetically unchanged for over 1,000 years and have a strong immune system due to difficult farming conditions in Iceland.
  4. The female sheep is a ewe and the male sheep is a ram. Icelandic ewe weigh an average of 150-160 pounds, and Icelandic ram weigh around 200-220 pounds.
  5. The Icelandic breed is famous for their wool, which is dual-coated. There are both inner and outer fibres, providing brilliant protection against the cold in Iceland.
  6. They enjoy the silence and serenity of Iceland, being very quiet animals. On the rare occasions they do ‘talk’, their call is very soft and gentle.
  7. A gene called the ‘Thoka’ gene, named after the first ewe to carry the gene, has been found in Icelandic sheep, which causes a higher rate of triplets. The gene causes an increase in fertility, which can cause triplets, quads, quints and even sextuplets to be born!
  8. Icelandic sheep have evolved to survive on pasture and foliage, as Iceland is not a grain-producing country due to its climate.
  9. These sheep are considered a mountain breed.
  10. The average yearly fleece of the Icelandic sheep weighs around 2-3 kilograms. The sheep are normally sheared twice a year.

Icelandic sheep: history and heritage

Originally imported to Iceland in the 9th and 10th centuries by Viking settlers, Icelandic sheep are part of the North European short-tailed variety, which was dominant in Scandinavian and the British Isles during the 8th and 9th century.

There have been very few attempts to ‘improve’ Icelandic sheep through cross-breeding with different varieties. Those few attempts that were made proved calamitous due to the spread of disease. Famers took drastic measures to solve this problem by culling all animals that were the result of crossbreeding.

Icelandic sheep today are known to be one of the purest and oldest domesticated sheep breeds in the world, with farmers selectively breeding their flock within the breed. Their immune systems are strong, with all diseases resulting from crossbreeding being eliminated due to the drastic cull.

In the late 1970s, there were almost 900,000 sheep in Iceland, which equated to around one sheep per resident of Iceland. Numbers have been falling in recent years to just under approximately 500,000 at the current time.

What are the Icelandic sheep used for?

From wool production to milk, the Icelanders certainly know how to get the best of this breed. Let’s find out the main uses of Iceland's sheep.

Wool Products

The famous wool of the Icelandic sheep is dual-coated for maximum protection against the harsh wintry weather in Iceland. The inner and outer layers of their dual-layered coat have different textures and properties, with the long outer coat being called tog (tow) and the finer internal coat is called þel (thel).

Fibers from the external coat are longer, tougher, shiny and waterproof, being built to withstand very low temperatures. On the other hand, threads from the internal coat are finer, softer and insulating, also providing great protection from the sub-Arctic cold.

These different fibres are used to make different woollen products. Both fibres can also be combined to create a unique wool called Lopi, which can only be made from the fleece of Icelandic sheep. Lopi is used to hand-knit the famous Icelandic sweaters – a very popular souvenir!

Icelandic sweaters: Lopapeysa

The traditional Icelandic sweater, or lopapeysa as the locals call it, is a thick jumper hand-knitted using Icelandic sheep wool. Traditional lopapeysa are made from uncoloured wool, making them either white, grey, brown or black.

Lopapeysa can be itchy, but, as many Icelandic children wear the wool since they’re born, they become resistant to the itching! These sweaters are often worn close to the body to keep warmer. Socks, blankets and gloves are other popular products made from this sheep wool.

Meat production

In Iceland, the sheep are bred primarily for their meat. Lambs are born small but grow quickly, reaching breeding age at 12 months old for ewes and around 6 months for the Icelandic rams.

Icelandic sheep are free to roam the pastures in summer and are usually slaughtered straight after the summer or fall season at around four to five months old. Icelandic sheep are not fed any grains, hormones or antibiotics, grazing solely on the pastures in summer. They are fed hay or silage (green foliage) during winter.

Their meat is fine-grained and tender with a distinct flavor and is used in many traditional Icelandic recipes, such as Icelandic lamb soup, called Kjötsúpa in Icelandic. The meat of the older sheep is sold for a cheap price and usually used to make stews.

Icelandic sheep milk

No longer commercially milked, Icelandic sheep were the main dairy animals in Iceland for over 1,000 years. In the 1940s, mechanized haying allowed cows to become the main dairy animals due to increased hay production. Previously, these sheep were known as the ‘poor man’s cow’, as only richer farmers could afford to produce the amount of hay needed to keep a cow.

Ewes can produce a lot of milk: around one to two liters per day. Used to produce yogurt, butter and cheese, their milk is creamy and sweet. A traditional Icelandic soft cheese, called skyr, is also produced from this milk. Some small Icelandic farms still milk Icelandic sheep.

Réttir: Gathering sheep for the winter

In September, farmers in Iceland gather all their sheep in one place. The sheep are free to roam during the summer months, but are gathered together for winter in a process called Réttir.

Réttir can take up to a week, as the sheep can move quickly and are very spread out. With little flocking instinct, Icelandic sheep can be quite individualistic, making it difficult for farmers to round their flock up.

Luckily the farmers don’t have to take on this demanding task by themselves; a popular pastime in Iceland, many locals join in with Réttir to help the farmers round up the sheep. A mixture of horse riders, sheepdogs and people on foot help to gather the sheep ready for the winter season. There are now tourist trips and tours you can go on to see Réttir for yourself.

Seeing sheep in Iceland

Icelandic sheep can be spotted all around the country, roaming through the pastures during the summer months. As you explore this scenic country, you’ll be sure to spot some sheep along your way. During summer, the sheep often head up to the mountains until autumn comes. You may even see Icelandic sheep jumping over a stream if you’re lucky!

On your tour around the Golden Circle, keep a look out for some fluffy friends roaming the hills. If you’d like to see some sheep up close, you can head to Reykjavik Farm Park and Zoo in Laugardalur Valley to see their small flock. May is a great time to visit if you’d like to see the newborn lambs.

When driving in Iceland, be careful when you see sheep nearby. On your tour around the country, you’ll most likely notice lots of road signs warning drivers about the sheep. Icelandic sheep may try to cross the road dangerously close to vehicles, especially when a number of sheep are on one side of the road and some are left on the other side.

If a lamb is on one side of the road and the mother on the other side, the lamb will normally cross to the mother, so be patient and wait until the sheep are safe before proceeding. Remember not to honk, as this will scare the sheep and can cause them to scatter in different directions.

It’s important to be aware of the sheep when driving in Iceland; just stay cautious and alert to respect the sheep as you travel around. You can stop at some gorgeous spots along the way or even visit a farm to see the sheep up close.
