The reindeer (Rangifer tarandus), also known as caribou in North America, is a species of deer with circumpolar distribution, native to arctic, subarctic, tundra, boreal, and mountainous regions of northern Europe, Siberia, and North America. This includes both sedentary and migratory populations. Rangifer herd size varies greatly in different geographic regions. The Taimyr herd of migrating tundra reindeer (R.t. sibiricus) in Russia is the largest wild reindeer herd in the world, with numbers varying between 400,000 and 1,000,000. The second largest is the migratory woodland caribou (R.t. caribou) George River herd in Canada, with variations between 28,000 and 385,000.
Rangifer vary in colour and size from the smallest, the Peary caribou, to the largest, the boreal woodland caribou. The North American range of caribou extends from Alaska, through the Yukon, the Northwest Territories, Nunavut, into the boreal forest and south through the Canadian Rockies and the Columbia and Selkirk Mountains. Barren-ground, Porcupine caribou and Peary caribou live in the tundra, while the shy woodland caribou prefers the boreal forest. Two major subspecies in North America, the Porcupine caribou and the barren-ground caribou, form large herds and undertake lengthy seasonal migrations from birthing grounds, to summer and winter feeding grounds in the tundra and taiga. The migrations of Porcupine caribou herds are among the longest of any terrestrial mammal. Barren-ground caribou are also found in Kitaa in Greenland, but the larger herds are in Alaska, the Northwest Territories, and Nunavut.
While overall widespread and numerous, some of its subspecies are rare and at least one has already become extinct, for example, the Queen Charlotte Islands caribou, Canada. Historically the range of the sedentary boreal woodland caribou covered over half of present-day Canada, and into the northern States in the U.S.. Woodland caribou have disappeared from most of their original southern range and were designated as threatened in 2002 by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Environment Canada reported in 2011 that there were approximately 34,000 boreal caribou in 51 ranges remaining in Canada.(Environment Canada, 2011b). Siberian tundra reindeer herd are in decline. For this reason, Rangifer tarandus is considered to be vulnerable by the IUCN.
Human dependence on caribou/wild reindeer began in the Middle Pleistocene period. Arctic peoples, such as the Caribou Inuit, the inland-dwelling Inuit of the Kivalliq Region in northern Canada, the Caribou Clan in the Yukon, Inupiat, Inuvialuit, Hän, Northern Tutchone, and the Gwich'in (who followed the Porcupine Caribou for millennia), have depended on them for food, clothing, and shelter. Hunting of wild reindeer and herding of semi-domesticated reindeer (for meat, hides, antlers, milk and transportation) are important to several Arctic and Subarctic peoples.
The Sami people, (Laplanders), who live in four countries but are one people, have also depended on reindeer herding and fishing for centuries. In Lapland, reindeer pull pulks.
Male and female reindeer can grow antlers annually, although the proportion of females that grow antlers varies greatly between population and season. Antlers are typically larger on males.
In traditional festive legend, Santa Claus's reindeer pull a sleigh through the night sky to help Santa Claus deliver gifts to children on Christmas Eve.

Etymology
Rangifer tarandus
The name Rangifer, which Carl Linnaeus chose for the reindeer genus, was used by Albertus Magnus in his De animalibus, fol. Liber 22, Cap. 268: "Dicitur Rangyfer quasi ramifer". This word may go back to a Saami word raingo. For the origin of the word tarandus, which Linnaeus chose as the specific epithet, he made reference to Ulisse Aldrovandi's Quadrupedum omnium bisulcorum historia fol. 859-863, Cap. 30: De Tarando (1621). However, Aldrovandi - and before him Konrad Gesner - thought that rangifer and tarandus were two separate animals. In any case, the tarandos name goes back to Aristotle and Theophrastus - see 'In history' below.
Reindeer
The name rein (-deer) is of Norse origin (Old Norse hreinn, which again goes back to Proto-Germanic *hrainaz and Proto-Indo-European *kroinos meaning "horned animal").
The word deer was originally broader in meaning, but became more specific over time. In Middle English, der (Old English d?or) meant a wild animal of any kind. This was in contrast to cattle, which then meant any sort of domestic livestock that was easy to collect and remove from the land, from the idea of personal-property ownership (rather than real estate property) and related to modern chattel (property) and capital. Cognates of Old English d?or in other dead Germanic languages have the general sense of animal, such as Old High German tior, Old Norse djúr or dýr, Gothic dius, Old Saxon dier, and Old Frisian diar.
Caribou
The name caribou comes, through French, from Mi'kmaq qalipu, meaning "snow shoveler", referring to its habit of pawing through the snow for food.
Other local variants
Because of its importance to many cultures, Rangifer tarandus and some of its subspecies have names in many languages. In the Uralic languages, Sami *poatsoj (in Northern Sami boazu, in Lule Sami boatsoj, in Pite Sami båtsoj, in Southern Sami bovtse, in Inari Sami puásui), Meadow Mari pücö and Udmurt pud?ej, all referring to domesticated reindeer, go back to *pocaw, an Iranian loan word deriving from Proto-Indo-European *pe?u-, meaning "cattle". The Finnish name poro may also stem from the same.
With its range across North America and depth of history, Rangifer tarandus has countless aboriginal names. In Inuktitut, spoken in eastern Arctic North America, the caribou is known by the name tuktu. In the western North American Arctic, the term used by the Iñupiat is tuttu, or tutu. The Gwich'in people have over two dozen distinct caribou-related words.

Taxonomy and evolution
The species taxonomic name Rangifer tarandus was defined by Carl Linnaeus in 1758. The subspecies taxonomic name, Rangifer tarandus caribou was defined by Gmelin in 1788.
Based on Banfield's often-cited A Revision of the Reindeer and Caribou, Genus Rangifer (1961), R. t. caboti (Labrador caribou), R. t. osborni (Osborn's caribou--from British Columbia) and R. t. terraenovae (Newfoundland caribou) were considered invalid and included in R. t. caribou.
Some recent authorities have considered them all valid, even suggesting that they are quite distinct. In their book entitled Mammal Species of the World, American zoologist Don E. Wilson and DeeAnn Reeder agree with Valerius Geist, specialist on large North American mammals, that this range actually includes several subspecies.
Geist (2007) argued that the "true woodland caribou, the uniformly dark, small-maned type with the frontally emphasized, flat-beamed antlers", which is "scattered thinly along the southern rim of North American caribou distribution" has been incorrectly classified. He affirms that "true woodland caribou is very rare, in very great difficulties and requires the most urgent of attention."
In 2005, an analysis of mtDNA found differences between the caribou from Newfoundland, Labrador, south-western Canada and south-eastern Canada, but maintained all in R. t caribou.
Mallory and Hillis argued that, "Although the taxonomic designations reflect evolutionary events, they do not appear to reflect current ecological conditions. In numerous instances, populations of the same subspecies have evolved different demographic and behavioural adaptations, while populations from separate subspecies have evolved similar demographic and behavioural patterns... "[U]nderstanding ecotype in relation to existing ecological constraints and releases may be more important than the taxonomic relationships between populations."
Current classifications of Rangifer tarandus, either with prevailing taxonomy on subspecies, designations based on ecotypes, and natural population groupings, fail to capture "the variability of caribou across their range in Canada" needed for effective species conservation and management. "Across the range of a species, individuals may display considerable morphological, genetic, and behavioural variability reflective of both plasticity and adaptation to local environments." COSEWIC developed Designated Unit (DU) attribution to add to classifications already in use.
Subspecies
The canonical Mammal Species of the World (3rd ed.) recognizes fourteen subspecies, two of which are extinct.
The table above includes R. tarandus caboti (Labrador caribou), R. tarandus osborni (Osborn's caribou - from British Columbia) and R. tarandus terraenovae (Newfoundland caribou). Based on a review in 1961, these were considered invalid and included in R. tarandus caribou, but some recent authorities have considered them all valid, even suggesting that they are quite distinct. An analysis of mtDNA in 2005 found differences between the caribous from Newfoundland, Labrador, south-western Canada and south-eastern Canada, but maintained all in R. tarandus caribou.
There are seven subspecies of reindeer of which only two are found in Fennoscandia: Eurasian tundra (or mountain) reindeer (R. t. tarandus) in Norway, Sweden, Finland and Russia and Eurasian forest reindeer R. t. fennicus in Finland and Russia.
Two subspecies are found only in North America: the Porcupine caribou and Peary caribou. Barren-ground caribou are found in western Greenland, but the larger herds are in Alaska, the Northwest Territories and Nunavut.
According to Grubb, based on Banfield and considerably modified by Geist, these subspecies and divisions are considered valid: The Woodland caribou division includes R. t. buskensis, R. t. dawsoni, R. t. fennicus, R. t. phylarchus, and R. t. valentinae. Osborni populations are transitional between caribou and tarandus divisions. The Tarandus division, barren-ground caribou or reindeer include R. t. caboti (G.M. Allen, 1914), R. t. groenlandicus, R. t. pearsoni, R. t. sibiricus, and R. t. terraenovae. The Platyrhynchus division includes the R. t. pearyi or Peary caribou and the R. t. platyrhynchus or Svalbard reindeer
Some of the Rangifer tarandus subspecies may be further divided by ecotype depending on several behavioural factors - predominant habitat use (northern, tundra, mountain, forest, boreal forest, forest-dwelling, woodland, woodland (mountain), woodland (boreal), woodland (migratory), spacing (dispersed or aggregated), and migration (sedentary or migratory).
The "glacial-interglacial cycles of the upper Pleistocene had a major influence on the evolution" of Rangifer tarandus and other Arctic and sub-Arctic species. Isolation of Rangifer tarandus in refugia during the last glacial - the Wisconsin in North America and the Weichselian in Eurasia-shaped "intraspecific genetic variability" particularly between the North American and Eurasian parts of the Arctic.
In 1986 Kurtén reported that the oldest reindeer fossil was an "antler of tundra reindeer type from the sands of Süssenborn" in the Pleistocene (Günz) period (680,000 to 620,000 BP). By the 4-Würm period (110-70,000 to 12-10,000) its European range was very extensive. Reindeer occurred in
... Spain, Italy and southern Russia. Reindeer [was] particularly abundant in the Magdalenian deposits from the late part of the 4-Wurm just before the end of the Ice Age: at that time and at the early Mesolithic it was the game animal for many tribes. The supply began to get low during the Mesolithic, when reindeers retired to the north.
"In spite of the great variation, all the Pleistocene and living reindeer belong to the same species."
Humans started hunting reindeer in the Mesolithic and Neolithic periods, and humans are today the main predator in many areas. Norway and Greenland have unbroken traditions of hunting wild reindeer from the last glacial period until the present day. In the non-forested mountains of central Norway, such as Jotunheimen, it is still possible to find remains of stone-built trapping pits, guiding fences, and bow rests, built especially for hunting reindeer. These can, with some certainty, be dated to the Migration Period, although it is not unlikely that they have been in use since the Stone Age.
Physical characteristics
Antlers
In most populations both sexes grow antlers; the reindeer is the only cervid species in which females grow them as well as males.
There is considerable variation between subspecies in the size of the antlers (e.g. they are rather small and spindly in the northernmost subspecies), but on average the bull reindeer's antlers are the second largest of any extant deer, after the moose. In the largest subspecies, the antlers of large males can range up to 100 cm (39 in) in width and 135 cm (53 in) in beam length. They have the largest antlers relative to body size among living deer species. Antler size measured in number of points reflects the nutritional status of the reindeer and climate variation of its environment. The number of points on male reindeer increased from birth to five-years of age and remained relatively constant from then on. "In male caribou, antler mass (but not the number of tines) varies in concert with body mass." While antlers of bull woodland caribou are typically smaller than barren-ground caribou, they can be over one metre across. They are flattened, compact, and relatively dense. Geist describes them as frontally emphasized, flat-beamed antlers. Woodland caribou antlers are thicker and broader than those of the barren-ground caribou, and their legs and heads are longer. Quebec-Labrador bull caribou antlers can be significantly larger and wider than other woodland caribou. Central barren-ground bull caribou are perhaps the most diverse in configuration and can grow to be very high and wide. Mountain caribou are typically the most massive with the largest circumference measurements.
The antler's main beam begins at the brow "extending posterior over the shoulders and bowing so that the tips point forwards. The prominent, palmate brow tines extend forward, over the face." The antlers typically have two separate groups of points, lower and upper.
Antlers begin to grow on male reindeer in March or April and on female reindeer in May or June. This process is called antlerogenesis. Antlers grow very quickly every year on the males. As the antler grows it is covered in thick velvet, filled with blood vessels and spongy in texture. The antler velvet of the barren-ground caribou and woodland caribou are dark chocolate brown. The velvet that covers growing antlers is a highly vascularised skin. This velvet is dark brown on woodland or barren-ground caribou and slate grey on Peary caribou and the Dolphin-Union Caribou herd. Velvet lumps in March can develop into a rack measuring more than a metre in length (3 ft) by August.
When the antler growth is fully grown and hardened, the velvet is shed or rubbed off. To the Inuit, for whom, the caribou is a "culturally important keystone species", the months are named after landmarks in the caribou life cycle. For example, amiraijaut in the Igloolik region is "when velvet falls off caribou antlers."
Male reindeer used their antlers to compete with other males during the mating season. In describing woodland caribou, SARA wrote, "During the rut, males engage in frequent and furious sparring battles with their antlers. Large males with large antlers do most of the mating." Reindeer continue to migrate until the bull reindeer has spent the back fat.
In late autumn or early winter after the rut, male reindeer lose their antlers, growing a new pair the next summer with a larger rack than the previous year. Female reindeer keep their antlers until they calve. In the Scandinavian populations, old males' antlers fall off in December, young males' fall off in the early spring, and females' fall off in the summer.
When bull reindeer shed their antlers in early to midwinter, the antlered female reindeer acquire the highest ranks in the feeding hierarchy, gaining access to the best forage areas. These cows are healthier than those without antlers. Calves whose mothers do not have antlers are more prone to disease and have significantly higher mortality. Females in good nutritional condition, for example, during a mild winter with good winter range quality, may grow new antlers earlier as antler growth requires high intake.
According to a respected Igloolik elder, Noah Piugaattuk, who was one of the last outpost camp leaders, caribou (tuktu) antlers,
...get detached every year... Young males lose the velvet from the antlers much more quickly than female caribou even though they are not fully mature. They start to work with their antlers just as soon as the velvet starts to fall off. The young males engage in fights with their antlers towards autumn... soon after the velvet had fallen off they will be red, as they start to get bleached their colour changes... When the velvet starts to fall off the antler is red because the antler is made from blood. The antler is the blood that has hardened, in fact the core of the antler is still bloody when the velvet starts to fall off, at least close to the base.
According to the Igloolik Oral History Project (IOHP), "Caribou antlers provided the Inuit with a myriad of implements, from snow knives and shovels to drying racks and seal-hunting tools. A complex set of terms describes each part of the antler and relates it to its various uses". Currently, the larger racks of antlers are used by Inuit as materials for carving. Iqaluit-based Jackoposie Oopakak's 1989 carving, entitled Nunali, which means ""place where people live", and which is part of the permanent collection of the National Gallery of Canada, includes a massive set of caribou antlers on which he has intricately carved the miniaturized world of the Inuit with "Arctic birds, caribou, polar bears, seals, and whales are interspersed with human activities of fishing, hunting, cleaning skins, stretching boots, and travelling by dog sled and kayak...from the base of the antlers to the tip of each branch".
Pelt
The colour of the fur varies considerably, both between individuals and depending on season and subspecies. Northern populations, which usually are relatively small, are whiter, while southern populations, which typically are relatively large, are darker. This can be seen well in North America, where the northernmost subspecies, the Peary caribou, is the whitest and smallest subspecies of the continent, while the southernmost subspecies, the woodland caribou, is the darkest and largest.
The coat has two layers of fur: a dense woolly undercoat and longer-haired overcoat consisting of hollow, air-filled hairs. Fur is the primary insulation factor that allows reindeer to regulate their core body temperature in relation to their environment, the thermogradient, even if the temperature rises to 100 °F (38 °C). In 1913 Dugmore noted how the woodland caribou swim so high out of the water, unlike any other mammal, because their hollow, "air-filled, quill-like hair" acts as a supporting "life jacket."
Heat exchange
Blood moving into the legs is cooled by blood returning to the body in a countercurrent heat exchange (CCHE), a highly efficient means of minimizing heat loss through the skin's surface. In the CCHE mechanism, in cold weather, blood vessels are closely knotted and intertwined with arteries to the skin and appendages that carry warm blood with veins returning to the body that carry cold blood causing the warm arterial blood to exchange heat with the cold venous blood. In this way, their legs for example are kept cool, maintaining the core body temperature nearly 30 °C (54 °F) higher with less heat lost to the environment. Heat is recycled instead of being dissipated. The "heart does not have to pump blood as rapidly in order to maintain a constant body core temperature and thus, metabolic rate." CCHE is present in animals like reindeer, fox and moose living in extreme conditions of cold or hot weather as a mechanism for retaining the heat in (or out of) the body. These are countercurrent exchange systems with the same fluid, usually blood, in a circuit, used for both directions of flow.
Reindeer have specialised counter-current vascular heat exchange in their nasal passages. Temperature gradient along the nasal mucosa is under physiological control. Incoming cold air is warmed by body heat before entering the lungs, and water is condensed from the expired air and captured before the reindeer's breath is exhaled, used to moisten dry incoming air and possibly absorbed into the blood through the mucous membranes. Like moose, caribou have specialised noses featuring nasal turbinate bones that dramatically increase the surface area within the nostrils.
Hooves
The reindeer has large feet with crescent-shaped, cloven hooves for walking in snow or swamps. According to the Species at Risk Public Registry (SARA), woodland,
"Caribou have large feet with four toes. In addition to two small ones, called "dew claws," they have two large, crescent-shaped toes that support most of their weight and serve as shovels when digging for food under snow. These large concave hooves offer stable support on wet, soggy ground and on crusty snow. The pads of the hoof change from a thick, fleshy shape in the summer to become hard and thin in the winter months, reducing the animal's exposure to the cold ground. Additional winter protection comes from the long hair between the "toes"; it covers the pads so the caribou walks only on the horny rim of the hooves."
Reindeer hooves adapt to the season: in the summer, when the tundra is soft and wet, the footpads become sponge-like and provide extra traction. In the winter, the pads shrink and tighten, exposing the rim of the hoof, which cuts into the ice and crusted snow to keep it from slipping. This also enables them to dig down (an activity known as "cratering") through the snow to their favorite food, a lichen known as reindeer moss.
Size
The females usually measure 162-205 cm (64-81 in) in length and weigh 80-120 kg (180-260 lb). The males (or "bulls") are typically larger (to an extent which varies between the different subspecies), measuring 180-214 cm (71-84 in) in length and usually weighing 159-182 kg (351-401 lb). Exceptionally large males have weighed as much as 318 kg (701 lb). Weight varies drastically seasonally with males losing as much as 40% of their pre-rut weight.
Shoulder height is typically 85 to 150 cm (33 to 59 in), and the tail is 14 to 20 cm (5.5 to 7.9 in) long.
The reindeer from Svalbard are the smallest. They are also relatively short-legged and may have a shoulder height of as little as 80 cm (31 in), thereby following Allen's rule.
Clicking sound
The knees of many species of reindeer are adapted to produce a clicking sound as they walk. The sounds originate in the tendons of the knees and may be audible from ten meters away. The frequency of the knee-clicks is one of a range of signals that establish relative positions on a dominance scale among reindeer. "Specifically, loud knee-clicking is discovered to be an honest signal of body size, providing an exceptional example of the potential for non-vocal acoustic communication in mammals." The clicking sound made by reindeer as they walk is caused by small tendons slipping over bone protuberances (sesamoid bones) in their feet. The sound is made when a reindeer is walking or running, occurring when the full weight of the foot is on the ground or just after it is relieved of the weight.<ref="Dugmore1913" />
Eyes
A study by researchers from University College London in 2011 revealed that reindeer can see light with wavelengths as short as 320 nm (i.e. in the ultraviolet range), considerably below the human threshold of 400 nm. It is thought that this ability helps them to survive in the Arctic, because many objects that blend into the landscape in light visible to humans, such as urine and fur, produce sharp contrasts in ultraviolet. A study at the University of Tromsø has confirmed that "Arctic reindeer eyes change in colour through the seasons from gold through to blue to help them better detect predators...".
Biology and behaviour
Diet
Reindeer are ruminants, having a four-chambered stomach. They mainly eat lichens in winter, especially reindeer lichen - a unique adaptation among mammals - and are the "only large mammal able to metabolize lichen owing to specialized bacteria and protozoa in their gut.". They are the only animals except for some gastropods in which the enzyme lichenase, which breaks down lichenin to glucose, has been found. However, they also eat the leaves of willows and birches, as well as sedges and grasses. They have been known to eat their own fallen antlers, probably for calcium. There is some evidence to suggest that on occasion, especially in the spring when they are nutritionally stressed, they will also feed on small rodents such as lemmings, fish such as Arctic char, and bird eggs. Reindeer herded by the Chukchis have been known to devour mushrooms enthusiastically in late summer.
Seasonal body composition
Reindeer have developed adaptations for optimal metabolic efficiency during warm months as well as for during cold months. The body composition of reindeer varies highly with the seasons. Of particular interest is the body composition and diet of breeding and non-breeding females between seasons. Breeding females have more body mass than non-breeding females between the months of March and September with a difference of around 10 kg more than non-breeding females. From November to December, non-breeding females have more body mass than breeding females as non-breeding females were able to focus their energies towards storage during colder months rather than lactation and reproduction. Body masses of both breeding and non-breeding females peaked in September. During the months of March through April, breeding females have more fat mass than the nonbreeding females with a difference of almost 3 kg. After this however, nonbreeding females on average have a higher fat mass than the breeding females.
The environmental variations play a large part in reindeer nutrition, as winter nutrition is crucial to adult and neonatal survival rates. Lichens are a staple during the winter months as they're a readily available food source, which reduces the reliance on stored body reserves. Lichens are a crucial part of the reindeer diet, however they are less prevalent in the diet of pregnant reindeer compared to non-pregnant individuals. The amount of lichen in a diet is found more in non-pregnant adult diets than pregnant individuals due to the lack of nutritional value. Although lichens are high in carbohydrates, they are lacking in essential proteins that vascular plants provide. The amount of lichen in a diet decreases in latitude that results in nutritional stress being higher in areas with low lichen abundance.
Reproduction and life-cycle
Reindeer mate in late September to early November, and the gestation period is about 228-234 days. During the mating season, males battle for access to females. Two males will lock each other's antlers together and try to push each other away. The most dominant males can collect as many as 15-20 females to mate with. A male will stop eating during this time and lose much of his body reserves.
To calve, "females travel to isolated, relatively predator-free areas such as islands in lakes, peatlands, lakeshores, or tundra." As females select the habitat for the birth of their calves, they are more wary than males. Dugmore noted that in their seasonal migrations the herd follows a doe for that reason.<ref="Dugmore1913" /> Newborns weigh on average 6 kg (13 lb). In May or June the calves are born. After 45 days, the calves are able to graze and forage but continue suckling until the following autumn when they become independent from their mothers.
Males live 4 years less than the females whose maximum longevity is about 17 years. Females with a normal body size who have had sufficient summer nutrition, can begin breeding anytime between the ages of one to three years. When a female has undergone nutritional stress, it is possible for her to not reproduce for the year. Dominant males, those with larger body size and antler racks, inseminate more than one doe a season.}
Social structure, migration and range
Some populations of the North American caribou, for example many herds in the subspecies barren-ground caribou and some woodland caribou in Ungava and Labrador, migrate the farthest of any terrestrial mammal, travelling up to 5,000 km (3,000 mi) a year, and covering 1,000,000 km2 (400,000 sq mi). Other North American populations, the woodland caribou (boreal) for example, are largely sedentary. The european populations are known to have shorter migrations. Island herds such as the subspecies R. t. pearsoni and R. t. platyrhynchus make local movements. Migrating reindeer can be negatively affected by parasite loads. Severely infected individuals are weak and probably have shortened lifespans, but parasite levels vary between populations. Infections create an effect known as culling: infected migrating animals are less likely to complete the migration.
Normally travelling about 19-55 km (12-34 mi) a day while migrating, the caribou can run at speeds of 60-80 km/h (37-50 mph). Young caribou can already outrun an Olympic sprinter when only a day old. During the spring migration smaller herds will group together to form larger herds of 50,000 to 500,000 animals, but during autumn migrations the groups become smaller, and the reindeer begin to mate. During winter, reindeer travel to forested areas to forage under the snow. By spring, groups leave their winter grounds to go to the calving grounds. A reindeer can swim easily and quickly, normally at about 6.5 km/h (4 mph) but if necessary at 10 km/h (6 mph), and migrating herds will not hesitate to swim across a large lake or broad river.
As an adaptation to their Arctic environment, they have lost their circadian rhythm.
Ecology
Distribution and habitat
Originally, the reindeer was found in Scandinavia, eastern Europe, Greenland, Russia, Mongolia, and northern China north of the 50th latitude. In North America, it was found in Canada, Alaska, and the northern conterminous USA from Washington to Maine. In the 19th century, it was apparently still present in southern Idaho. Even in historical times, it probably occurred naturally in Ireland. During the late Pleistocene era, reindeer occurred as far south as Nevada and Tennessee in North America, and as far south as Spain in Europe. Today, wild reindeer have disappeared from these areas, especially from the southern parts, where it vanished almost everywhere. Large populations of wild reindeer are still found in Norway, Finland, Siberia, Greenland, Alaska, and Canada.
According to the Grubb (2005), Rangifer tarandus is "circumboreal in the tundra and taiga" from "Svalbard, Norway, Finland, Russia, Alaska (USA) and Canada including most Arctic islands, and Greenland, south to northern Mongolia, China (Inner Mongolia; now only domesticated or feral?), Sakhalin Island, and USA (Northern Idaho and the Great Lakes region). Reindeer were introduced to, and feral in, Iceland, Kerguelen Islands, South Georgia Island, Pribilof Islands, St. Matthew Island."
There is strong regional variation in Rangifer herd size. There are large population differences among individual herds, and the size of individual herds has varied greatly since 1970. The largest of all herds (Taimyr, Russia) has varied between 400,000 and 1,000,000; the second largest herd (George River, Canada) has varied between 28,000 and 385,000.
While Rangifer is a widespread and numerous genus in the northern Holarctic, being present in both tundra and taiga (boreal forest), by 2013, many herds had "unusually low numbers" and their winter ranges in particular were smaller than they used to be. Caribou and reindeer numbers have fluctuated historically, but many herds are in decline across their range. This global decline is linked to climate change for northern, migratory herds and industrial disturbance of habitat for non-migratory herds.
In November 2016, it was reported that more than 81,000 reindeer in Russia had died as a result of climate change. Longer autumns leading to increased amounts of freezing rain created a few inches of ice over lichen, starving many reindeer.
Predators
A variety of predators prey heavily on reindeer, including over-hunting by people in some areas, which contributes to the decline of populations.
Golden eagles prey on calves and are the most prolific hunter on calving grounds. Wolverines will take newborn calves or birthing cows, as well as (less commonly) infirm adults.
Brown bears and polar bears prey on reindeer of all ages, but like the wolverines they are most likely to attack weaker animals, such as calves and sick deer, since healthy adult reindeer can usually outpace a bear. The grey wolf is the most effective natural predator of adult reindeer and sometimes takes large numbers, especially during the winter. Some wolf packs as well as individual grizzly bears in Canada may follow and live off of a particular reindeer herd year round.
Additionally, as carrion, reindeer may be scavenged opportunistically by foxes, hawks and ravens.
Blood-sucking insects, such as mosquitoes (Culicidae), black flies (Simuliidae), oestrid flies (warble flies) Hypoderma tarandi and nose bot flies (Cephenemyia trompe), are a plague to reindeer during the summer and can cause enough stress to inhibit feeding and calving behaviours. An adult reindeer will lose perhaps about 1 liter (about 2 US pints) of blood to biting insects for every week it spends in the tundra. The population numbers of some of these predators is influenced by the migration of reindeer. Tormenting insects keep caribou on the move searching for windy areas like hilltops and mountain ridges, rock reefs, lakeshore and forest openings, or snow patches that offer respite from the buzzing horde. Gathering in large herds is another strategy caribou use to block insects.
In one case, the entire body of a reindeer was found in the stomach of a Greenland shark, a species found in the far northern Atlantic, although this was possibly a case of scavenging, considering the dissimilarity of habitats between the ungulate and the large, slow-moving fish.
Other threats
White-tailed deer (Odocoileus virginianus) commonly carry meningeal worm or brainworm, a nematode parasite that causes reindeer, moose (Alces alces), elk (Cervus canadensis), and mule deer (Odocoileus hemionus) to develop fatal neurological symptoms which include a loss of fear of humans. White-tailed deer that carry this worm are partly immune to it.
Changes in climate and habitat beginning in the twentieth century have expanded range overlap between white-tailed deer and caribou, increasing the frequency of infection within the reindeer population. This increase in infection is a concern for wildlife managers. Human activities, such as "clear-cutting forestry practices, forest fires, and the clearing for agriculture, roadways, railways, and power lines," favour the conversion of habitats into the preferred habitat of the white-tailed deer-"open forest interspersed with meadows, clearings, grasslands, and riparian flatlands."

In 2013, the Taimyr herd in Russia was the largest herd in the world. In 2000, the herd increased to 1,000,000 but by 2009, there were 700,000 animals. In the 1950s, there were 110,000.
There are three large herds of migratory tundra wild reindeer in central Siberia's Yakutia region: Lena-Olenek, Yana-Indigirka and Sundrun herds. While the population of the Lena-Olenek herd is stable, the others are declining.
Further east again, the Chukotka herd is also in decline. In 1971, there were 587,000 animals. They recovered after a severe decline in 1986, to only 32,200 individuals, but their numbers fell again. According to Kolpashikov, by 2009 there were less than 70,000.
North America
There are four living subspecies of R. tarandus, locally known in North America as caribou: R. t. granti (Porcupine caribou), R. t. caribou subdivided into ecotypes: woodland (boreal), woodland (migratory), woodland (montane), R. t. groenlandicus and R. t. pearyi.
In North America, because of its vast range in a wide diversity of ecosystems, the subspecies Rangifer tarandus caribou is further distinguished by a number of ecotypes, including boreal woodland caribou, mountain woodland caribou and migratory woodland caribou). Populations--caribou that do not migrate--or herds--those that do migrate--may not fit into narrow ecotypes. For example, Banfield's 1961 classification of the migratory George River Caribou Herd, in the Ungava region of Quebec, as subspecies Rangifer tarandus caribou, woodland caribou, remains--although other woodland caribou are mainly sedentary.
Rangifer tarandus is "endangered in Canada in regions such as south-east British Columbia at the Canadian-USA border, along the Columbia, Kootenay and Kootenai rivers and around Kootenay Lake. Rangifer tarandus is endangered in the United States in Idaho and Washington. R. t. pearyi is on the IUCN endangered list." According to Geist, the "woodland caribou is highly endangered throughout its distribution right into Ontario."
United States
Although there are remnant populations of R. t. caribou boreal woodland caribou in the northern United States, most of U.S. caribou populations are in Alaska.
Alaska
There are four herds in Alaska, the Western Arctic herd, Teshekpuk Lake herd, the Central Arctic herd and the Porcupine herd, which is transnational as its migratory range extends far into Canada's north. The largest is the Western Arctic Caribou Herd but the smaller Porcupine caribou herd has the longest migration of any terrestrial mammal on earth with a vast historical range.
Porcupine caribou herd
The Porcupine caribou herd are transnational and migratory. The herds are named after their birthing grounds, for example, the Porcupine River, which runs through a large part of the range of the Porcupine herd. Individual herds of migratory caribou once had over a million animals per herd, and could taking over ten days to cross the Yukon River, but these numbers dramatically declined with habitat disturbance and degradation. Though numbers fluctuate, the herd comprises approximately 169,000 animals (based on a July 2010 photocensus). The Porcupine herd's annual migrations of 1,500 miles (2,400 km) are among the longest of any terrestrial mammal. Their range spans approximately 260,000 km2 (64,000,000 acres), from Dawson City, Yukon to Aklavik, NWT to Kaktovik, Alaska on the Beaufort Sea. The Porcupine caribou or Grant's caribou (Rangifer tarandus granti) is a subspecies with a vast range that includes northeastern Alaska and the Yukon, and is therefore cooperatively managed by government agencies and aboriginal peoples from both countries. The Gwich'in people, followed the Porcupine caribou herd--their primary source of food, tools, and clothing--for thousands of years--according to oral tradition, for as long as 20,000 years. They continued their nomadic lifestyle until the 1870s. This herd is also traditional food for the Inupiat, Inuvialuit, Hän, and Northern Tutchone. There is currently controversy over whether possible future oil drilling on the coastal plains of the Arctic National Wildlife Refuge, encompassing much of the Porcupine caribou calving grounds, will have a severe negative impact on the caribou population or whether the caribou population will grow.
Unlike many other Rangifer tarandus subspecies and their ecotypes, the Porcupine herd is stable at relatively high numbers, but the 2013 photo-census was not counted by January 2014. The peak population in 1989 of 178,000 animals was followed by a decline by 2001 to 123,000. However, by 2010, there was a recovery and an increase to 169,000 animals.
Many Gwich'in people, who depend on the Porcupine caribou, still follow traditional caribou management practices that include a 1981 prohibition against selling caribou meat and limits on the number of caribou to be taken per hunting trip.
Western Arctic Caribou herd
The Western Arctic Caribou Herd is the largest of the three. The Western Arctic herd reached a low of 75,000 in the mid-1970s. In 1997 the 90,000 WACH changed their migration and wintered on Seward Peninsula. Alaska's reindeer herding industry has been concentrated on Seward Peninsula ever since the first shipment of reindeer was imported from eastern Siberia in 1892 as part of the Reindeer Project, an initiative to replace whale meat in the diet of the indigenous people of the region. For many years it was believed that the geography of the peninsula would prevent migrating caribou from mingling with domesticated reindeer who might otherwise join caribou herds when they left an area. However, in 1997 the domesticated reindeer joined the Western Arctic Caribou Herd on their summer migration and disappeared. The WACH reached a peak of 490,000 in 2003 and then declined to 325,000 in 2011.
Teshekpuk Lake and Central Arctic herds
In 2008, the Teshekpuk Lake herd had 64,107 animals and the Central Arctic herd had 67,000.
By 2017, the Teshekpuk herd numbers, whose calving grounds are in the region of the shallow Teshekpuk Lake, had declined to 41,000 animals. Teshekpuk Lake in the North Slope is in the traditional lands of the Iñupiat who depended on the Teshekpuk herd for millenia. Teshekpuk Lake is also in the National Petroleum Reserve-Alaska, where the U.S. Department of the Interior (DOI) had approved oil and gas drilling in January 11, 2006. The NPR-A is the "single largest parcel of public land in the United States" covering about 23 million acres". The reserve's eastern border sits about 100 miles to the west of the more famous Arctic National Wildlife Refuge. The leasing of Teshekpuk Lake land to industry was protested by the Iñupiat and others who sent 300,000 letters to the US Secretary of the Interior and ConocoPhillips CEO over the summer of 2006. On September 25, 2006, the U.S. District Court for the District of Alaska protected the wildlife habitat around the lake from an oil and gas lease sale.
In October 2017, U. S. Secretary of the Interior, Ryan Zinke, announced that as of December 6, 2017, lands under the administration of the U.S. Bureau of Land Management will be up for bid on the "largest offering of public lands for lease in the history of the [BLM] -- 10.3 million acres". The Prudhoe Bay Oil Field, near Prudhoe Bay, Alaska is situated between the Arctic National Wildlife Refuge to the east. Industry will be allowed to run "roads, pipelines and drill rigs" in the very sensitive habitat areas, including the the Teshekpuk caribou herd calving grounds. The Teshekpuk herd remains at the calving grounds for several weeks in spring before moving Teshekpuk Lake for relief from mosquitoes and botflies before their annual migration.
Reindeer imported to Alaska
Reindeer were imported from Siberia in the late 19th century and from Norway in the early 1900s as semi-domesticated livestock in Alaska. Reindeer interbreed with native caribou subspecies.
Canada
The barren-ground caribou subspecies R. t. groenlandicus, a long-distance migrant, includes large herds in the Northwest Territories and in Nunavut, for example the Beverly, the Ahiak and Qamanirjuaq herds. In 1996, the population of the Ahiak herd was approximately 250,000 animals.
Ahiak, Beverly, Qamanirjuaq herds
The Ahiak, Beverly, Qamanirjuaq herds are barren-ground caribou.
"The Beverly herd's crossing of the Thelon River to its traditional calving grounds near Beverly Lake was part of the lives of the Dene aboriginal people for 8000 years, as revealed by an unbroken archaeological record of deep layers of caribou bones and stone tools in the banks of the Thelon River (Gordon 2005)." The Beverly Herd (located primarily in Saskatchewan, Northwest Territories; portions in Nunavut, Manitoba, Alberta) and the Qamanirjuaq Herd (located primarily in Manitoba, Nunavut; portions in southeastern NWT, northeastern Saskatchewan) fall under the auspices of the Beverly and Qamanirjuaq Caribou Management Board. The Beverly herd, whose range spans the tundra from northern Manitoba and Saskatchewan and well into the Northwest Territories and Nunavut, had a peak population in 1994 of 276,000 or 294,000, but by 2011 there were approximately 124,000 caribou in the Beverly herd and 83,300 in the Ahiak herd. The calving grounds of the Beverly caribou herd are located around Queen Maud Gulf but the herd shifted its traditional birthing area. Caribou management agencies are concerned that deterioration and disturbance of habitat along with "parasites, predation and poor weather" are contributing to a cycling down of most caribou populations. It was suggested the Ahiak and Beverly herds switched calving grounds and the Beverly may have moved "near the western Queen Maud Gulf coast to the north of the herd's "traditional" calving ground in the Gary Lakes area north of Baker Lake." The "Beverly herd may have declined (similar to other Northwest Territories herds), and cows switched to the neighbouring Ahiak herd to maintain the advantages of gregarious calving." By 2011 there were approximately 124,000 caribou in the combined Beverly/Ahiak herd which represents a "50% or a 75% decline from the 1994 population estimate for the Beverly Herd."
The barren-ground caribou population on Southampton Island, Nunavut declined by almost 75%, from about 30,000 caribou in 1997 to 7,800 caribou in 2011.
Peary caribou on Baffin Island
The R. t. pearyi (Peary caribou), the smallest subspecies in North America, known as Tuktu in Inuktitut, are found in the northern islands of Nunavut and the Northwest Territories. They remain at low numbers after severe declines. On Baffin Island, the largest Arctic island, the population of Peary caribou peaked in the early 1990s to approximately 60,000 to 180,000. By 2012, in northern Baffin Island caribou numbers were considered to be at a "low in the cycle after a high in the 1990s" and in south Baffin Island, the population was estimated as between 1,065 and 2,067.
Northwest Territories
There are four barren-ground caribou herds in the Northwest Territories--Cape Bathurst, Bluenose West, Bluenose East and Bathurst. The Bluenose East caribou herd began a recovery with a population of approximately 122,000 in 2010. which is being credited to the establishment of Tuktut Nogait National Park. According to T. Davison 2010, CARMA 2011, the three other herds "declined 84-93% from peak sizes in the mid-1980s and 1990s.
R. t. caribou
The subspecies R. t. caribou commonly known as woodland caribou, is divided into ecotypes: boreal woodland caribou (also known as forest-dwelling), woodland caribou (boreal), mountain woodland caribou, and migratory woodland caribou. Caribou are classified by ecotype depending on several behavioural factors - predominant habitat use (northern, tundra, mountain, forest, boreal forest, forest-dwelling), spacing (dispersed or aggregated) and migration (sedentary or migratory).
In Canada, the national meta-population of the sedentary boreal ecotype spans the boreal forest from the Northwest Territories to Labrador. They prefer lichen-rich mature forests and mainly live in marshes, bogs, lakes, and river regions. The historic range of the boreal woodland caribou covered over half of present-day Canada, stretching from Alaska to Newfoundland and Labrador and as far south as New England, Idaho, and Washington. Woodland caribou have disappeared from most of their original southern range and only about 34,000 remain. The boreal woodland was designated as threatened in 2002.
George River caribou herd (GRCH)
The migratory George River caribou herd (GRCH), in the Ungava region of Quebec and Labrador in eastern Canada was once the world's largest herd with 800,000-900,000 animals. Although it is categorized as a subspecies Rangifer tarandus caribou, the woodland caribou, the GRCH is migratory woodland caribou and like the barren-ground caribou it's ecotype may be tundra caribou, Arctic, northern of migratory, not forest-dwelling and sedentary like most woodland caribou ecotypes. It is unlike most woodland caribou in that it is not sedentary. Since the mid-1990s, the herd declined sharply and by 2010, it was reduced to 74,131--a drop of up to 92%. A 2011 survey confirms a continuing decline of the George River migratory caribou herd population. By 2012 it was estimated to be about 27,600 animals, down from 385,000 in 2001 and 74,131 in 2010."
Leaf River caribou herd (LRCH)
The Leaf River caribou herd (LRCH), another migratory forest-tundra ecotype of the boreal woodland caribou, near the coast of Hudson Bay, increased from 270 000 individuals in 1991 to 628 000 in 2001. By 2011 the herd had decreased to 430 000 caribou. According to an international study on caribou populations, the George River and Leaf River herds, and other herds that migrate from Nunavik, Quebec and insular Newfoundland, could be threatened with extinction by 2080.
Queen Charlotte Islands caribou
The Queen Charlotte Islands caribou (R. tarandus dawsoni) from the Queen Charlotte Islands was believed to represent a distinct subspecies. It became extinct at the beginning of the 20th century. However, recent DNA analysis from mitochondrial DNA of the remains from those reindeer suggest that the animals from the Queen Charlotte Islands were not genetically distinct from the Canadian mainland reindeer subspecies.
Greenland
According to Kolpashikov et al. (2013) there were four main populations of wild R. t. groenlandicus, barren-ground caribou, in west Greenland in 2013. The Kangerlussuaq-Sisimiut caribou herd, the largest had a population of around 98,000 animals in 2007. The "second largest, Akia-Maniitsoq decreased from an estimated 46,000 in 2001 to about 17,400 in 2010. According to Cuyler, "one possible cause might be the topography, which prevents hunter access in the former while permitting access in the latter."
Norway
The last remaining wild tundra reindeer in Europe are found in portions of southern Norway. In southern Norway in the mountain ranges, there are about 30,000-35,000 reindeer with 23 different populations. The largest herd with about 10,000 individuals, is at Hardangervidda. By 2013 the greatest challenges to management were "loss of habitat and migration corridors to piecemeal infrastructure development and abandonment of reindeer habitat as a result of human activities and disturbance."
Norway is now preparing to apply for nomination as a World Heritage Site for areas with traces and traditions of reindeer hunting in Dovrefjell-Sunndalsfjella National Park, Reinheimen National Park and Rondane National Park in Central Sør-Norge (Southern Norway). There is in these parts of Norway an unbroken tradition of reindeer hunting from post-glacial Stone Age until today.
On 29 August 2016, the Norwegian Environment Agency announced the death of 323 reindeer by the effects of a lightning strike in Hardangervidda.
Svalbard reindeer
The Svalbard reindeer subspecies R. t. platyrhynchus from Svalbard island is very small compared to other subspecies (a phenomenon known as insular dwarfism), with females having a length of approximately 150 cm (59 in), and a weight around 53 kg (117 lb) in the spring and 70 kg (150 lb) in the autumn. Males are approximately 160 cm (63 in) long, and weigh around 65 kg (143 lb) in the spring and 90 kg (200 lb) in the autumn. The reindeer from Svalbard are also relatively short-legged and may have a shoulder height of as little as 80 cm (31 in), thereby following Allen's rule.
The Rangifer tarandus platyrhynchus subspecies, in Norway referred to as the Svalbard reindeer, seems to have evolved from large European reindeer. The Svalbard reindeer is special in several ways. Svalbard reindeer has peculiarities in its metabolism. The skeleton shows a remarkable relative shortening of the legs, thus parallelling many extinct insular deer species.
Finland
The Finnish forest reindeer (R. tarandus fennicus), is found in the wild in only two areas of the Fennoscandia peninsula of Northern Europe, in Finnish/Russian Karelia, and a small population in central south Finland. The Karelia population reaches far into Russia, however, so far that it remains an open question whether reindeer further to the east are R. t. fennicus as well. By 2007 reindeer experts were concerned about the collapse of the wild Finnish forest reindeer (Rangifer tarandus fennicus) in the eastern province of Kainuu. During the peak year of 2001, the Finnish forest reindeer population in Kainuu was established at 1,700. In a March 2007 helicopter count, only 960 individuals were detected.
Iceland
East Iceland has a small herd of about 2500-3000 animals. Iceland (increasing or are stable at high numbers 2013) Iceland: Reindeer were introduced to Iceland (17) in the late 1700s cited in. The Icelandic reindeer population in July 2013 was estimated at approximately 6000. With a hunting quota of 1,229 animals, the winter 2013-2014 population is expected to be around 4800 reindeer
British overseas territory experiment
A few reindeer from Norway were introduced to the South Atlantic island of South Georgia in the beginning of the 20th century. The South Georgian reindeer total some 2,600 animals in two distinct herds separated by glaciers. Although the flag and the coat of arms of the territory contain an image of a reindeer, a decision was taken in 2011 to completely eradicate the animals from the island because of the environmental damage they cause.
French overseas territory experiment
Around 4000 reindeer have been introduced into the French sub-Antarctic archipelago of Kerguelen Islands.
Conservation
Current status
While overall widespread and numerous, some subspecies are rare and at least one has already gone extinct. As of 2015, the IUCN has classified the reindeer as Vulnerable due to an observed population decline of 40% over the last ~25 years. According to IUCN Rangifer tarandus as a species is not endangered because of its overall large population and the widespread range.
In North America subspecies R. t. dawsoni is extinct. R. t. pearyi is endangered, R. t. caribou are designated as threatened and some individual populations are endangered. While the subspecies R. t. granti and R. t. groenlandicus are not designated as threatened, many individual herds--including some of the largest--are declining and there is much concern at the local level.
Rangifer tarandus is "endangered in Canada in regions such as south-east British Columbia at the Canadian-USA border, along the Columbia, Kootenay and Kootenai rivers and around Kootenay Lake. Rangifer tarandus is endangered in the United States in Idaho and Washington.
There is strong regional variation in Rangifer herd size, By 2013 many caribou herds in North America had "unusually low numbers" and their winter ranges in particular were smaller than they used to be. Caribou numbers have fluctuated historically, but many herds are in decline across their range. There are many factors contributing to the decline in numbers.
Boreal woodland caribou (COSEWIC designation as threatened)
Ongoing human development of their habitat has caused populations of woodland caribou to disappear from their original southern range. In particular, caribou were extirpated in many areas of eastern North America in the beginning of the 20th century. Woodland caribou were designated as threatened in 2002. Environment Canada reported in 2011 that there were approximately 34,000 boreal caribou in 51 ranges remaining in Canada (Environment Canada, 2011b). Professor Marco Musiani of the University of Calgary, said in a statement that "The woodland caribou is already an endangered species in southern Canada and the United States....[The] warming of the planet means the disappearance of their critical habitat in these regions. Caribou need undisturbed lichen-rich environments and these types of habitats are disappearing."
Woodland caribou have disappeared from most of their original southern range and were designated as threatened in 2002 by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Environment Canada reported in 2011 that there were approximately 34 000 boreal caribou in 51 ranges remaining in Canada.(Environment Canada, 2011b). "According to Geist, the "woodland caribou is highly endangered throughout its distribution right into Ontario."
In 2002 the Atlantic-Gaspésie population of the woodland caribou was designated as endangered by COSEWIC. The small isolated population of 200 animals was at risk from predation and habitat loss.
In 1991 COSEWIC assigned "endangered status" to the Banks Island and High Arctic populations of Peary caribou. The Low Arctic population of Peary caribou was designated as threatened. By 2004 all three were designated as "endangered."
Numbers have declined by about 72% over the last three generations, mostly because of catastrophic die-off likely related to severe icing episodes. The ice covers the vegetation and caribou starve. Voluntary restrictions on hunting by local people are in place, but have not stopped population declines. Because of the continuing decline and expected changes in long-term weather patterns, this subspecies is at imminent risk of extinction.
Relationship with humans
The reindeer has an important economic role for all circumpolar peoples, including the Saami, Nenets, Khants, Evenks, Yukaghirs, Chukchi, and Koryaks in Eurasia. It is believed that domestication started between the Bronze and Iron Ages. Siberian deer owners also use the reindeer to ride on (Siberian reindeer are larger than their Scandinavian relatives). For breeders, a single owner may own hundreds or even thousands of animals. The numbers of Russian herders have been drastically reduced since the fall of the Soviet Union. The sale of fur and meat is an important source of income. Reindeer were introduced into Alaska near the end of the 19th century; they interbreed with native caribou subspecies there. Reindeer herders on the Seward Peninsula have experienced significant losses to their herds from animals (such as wolves) following the wild caribou during their migrations.
Reindeer meat is popular in the Scandinavian countries. Reindeer meatballs are sold canned. Sautéed reindeer is the best-known dish in Lapland. In Alaska and Finland, reindeer sausage is sold in supermarkets and grocery stores. Reindeer meat is very tender and lean. It can be prepared fresh, but also dried, salted, hot- and cold-smoked. In addition to meat, almost all internal organs of reindeer can be eaten, some being traditional dishes. Furthermore, Lapin Poron liha, fresh reindeer meat completely produced and packed in Finnish Lapland, is protected in Europe with PDO classification.
Reindeer antler is powdered and sold as an aphrodisiac, nutritional or medicinal supplement to Asian markets.
The blood of the caribou was supposedly mixed with alcohol as drink by hunters and loggers in colonial Quebec to counter the cold. This drink is now enjoyed without the blood as a wine and whiskey drink known as Caribou.
Reindeer and indigenous peoples
Wild reindeer are still hunted in Greenland and in North America. In the traditional lifestyle of the Inuit people, Northern First Nations people, Alaska Natives, and the Kalaallit of Greenland, reindeer is an important source of food, clothing, shelter, and tools.
The Caribou Inuit, are inland-dwelling Inuit in present-day Nunavut's Keewatin Region, Canada, now known as the Kivalliq Region. They subsisted on caribou year-round, eating dried caribou meat in winter. The Ihalmiut are caribou Inuit that followed the Qamanirjuaq barren ground caribou herd.
There is an Inuit saying in the Kivalliq Region region:
The caribou feeds the wolf, but it is the wolf who keeps the caribou strong.
Elder Chief of Koyukuk and chair for the Western Arctic Caribou Herd Working Group, Benedict Jones or K'ughto'oodenool'o' represents the Middle Yukon River, Alaska. His grandmother was a member of the Caribou Clan, who travelled with the reindeer as a means to survive. In 1939, they were living the traditional life style at one of their hunting camps in Koyukuk near the location of what is now the Koyukuk National Wildlife Refuge. His grandmother made a pair of new mukluks in one day. K'ughto'oodenool'o' recounted story told by an elder, who "worked on the steamboats during the gold rush days out on the Yukon." In late August the caribou migrated from the Alaska Range up north to Huslia, Koyukuk, and the Tanana area. One year the steamboat was unable to continue they ran into a reindeer herd numbering estimated at a million animals, migrating across the Yukon. "They tied up for seven days waiting for the caribou to cross. "They ran out of wood for the steamboats, and had to go back down 40 miles to the wood pile to pick up some more wood. On the tenth day, they came back and they said there was still caribou going across the river night and day."
The Gwich'in, the indigenous people of northwestern Canada and northeastern Alaska, have been dependent on the international migratory Porcupine Caribou Herd for millenia. To them caribou--vadzaih--is the cultural symbol and a keystone subsistence species of the Gwich'in, just as the buffalo is to the Plains Indians. Innovative language revitalization projects are underway to document the language, and to enhance the writing and translation skills of younger Gwich'in speakers. In one project lead research associate and fluent speaker Gwich'in elder, Kenneth Frank, works with linguists which include young Gwich'in speakers affiliated with the Alaska Native Language Center at the University of Alaska in Fairbanks to document traditional knowledge of reindeer anatomy. The main goal of the research, was to "elicit not only what the Gwich'in know about caribou anatomy, but how they see caribou and what they say and believe about caribou that defines themselves, their dietary and nutritional needs, and their subsistence way of life." Elders have identified at least 150 descriptive Gwich'in names for all of the bones, organs, and tissues "Associated with the caribou's anatomy are not just descriptive Gwich'in names for all of the body parts including bones, organs, and tissues as well as "an encyclopedia of stories, songs, games, toys, ceremonies, traditional tools, skin clothing, personal names and surnames, and a highly developed ethnic cuisine."
In the 1980s, Gwich'in Traditional Management Practices were established to protect the Porcupine caribou, upon which the Gwich'in people depend. They "codified traditional principles of caribou management into tribal law" which include "limits on the harvest of caribou and procedures to be followed in processing and transporting caribou meat" and limits on the number of caribou to be taken per hunting trip.
Reindeer husbandry
The reindeer is the only domesticated deer in the world and was the last animal to be domesticated, though it may be more accurate to consider reindeer as semi-domesticated. Caribou in northern Fennoscandia (northern Norway, Sweden and Finland) as well in Kola Peninsula in Russia, are all semi-wild domestic reindeer (Rangifer tarandus domesticus), ear-marked by their owners and living in large fenced areas. Some reindeer in the area are truly domesticated, mostly used as draught animals (nowadays commonly for tourist entertainment and races, traditionally important for the nomadic Sámi). Domesticated reindeer have also been used for milk, e.g. in Norway.
There are only two genetically pure populations of wild caribous in Northern Europe: wild mountain reindeer (Rangifer tarandus ssp. tarandus) live in central Norway, with a population in 2007 of between 6,000 and 8,400 animals; and wild forest reindeer (Rangifer tarandus ssp. fennicus), in central and eastern Finland and in Russian Karelia, with a population of about 4,350, plus 1,500 in Arkhangelsk and 2,500 in Komi.
DNA analysis indicates that reindeer were independently domesticated in Fennoscandia and Western Russia (and possibly Eastern Russia). Reindeer have been herded for centuries by several Arctic and Subarctic people including the Sami and the Nenets. They are raised for their meat, hides, and antlers and, to a lesser extent, for milk and transportation. Reindeer are not considered fully domesticated, as they generally roam free on pasture grounds. In traditional nomadic herding, reindeer herders migrate with their herds between coast and inland areas according to an annual migration route and herds are keenly tended. However, reindeer were not bred in captivity, though they were tamed for milking as well as for use as draught animals or beasts of burden. Domesticated reindeer are shorter-legged and heavier than their wild counterparts.
The use of reindeer for transportation is common among the nomadic peoples of northern Russia (but not any more in Scandinavia). Although a sled drawn by 20 reindeer will cover no more than 20-25 km a day (compared to 7-10 km on foot, 70-80 km by a dog sled loaded with cargo, and 150-180 km by a dog sled without cargo), it has the advantage that the reindeer will discover their own food, while a pack of 5-7 sled dogs requires 10-14 kg of fresh fish a day.
The use of reindeer as semi-domesticated livestock in Alaska was introduced in the late 19th century by the U.S. Revenue Cutter Service, with assistance from Sheldon Jackson, as a means of providing a livelihood for Native peoples there. Reindeer were imported first from Siberia, and later also from Norway. A regular mail run in Wales, Alaska, used a sleigh drawn by reindeer. In Alaska, reindeer herders use satellite telemetry to track their herds, using online maps and databases to chart the herd's progress.
Domesticated reindeer are mostly found in northern Fennoscandia and Russia, with a herd of approximately 150-170 reindeer living around the Cairngorms region in Scotland. The last remaining wild tundra reindeer in Europe are found in portions of southern Norway. The International Centre for Reindeer Husbandry (ICR), a circumpolar organization, was established in 2005 by the Norwegian government. ICR represents over 20 indigenous reindeer peoples and about 100,000 reindeer herders in 9 different national states. In Finland, there are about 6,000 reindeer herders, most of whom keep small herds of less than 50 reindeer to raise additional income. With 185,000 reindeer (2001), the industry produces 2,000 tons of reindeer meat and generates 35 million euros annually. 70% of the meat is sold to slaughterhouses. Reindeer herders are eligible for national and EU agricultural subsidies, which constituted 15% of their income. Reindeer herding is of central importance for the local economies of small communities in sparsely populated rural Lapland.
Currently, many reindeer herders are heavily dependent on diesel fuel to provide for electric generators and snowmobile transportation, although solar photovoltaic systems can be used to reduce diesel dependency.
In history
Reindeer hunting by humans has a very long history, and wild reindeer "may well be the species of single greatest importance in the entire anthropological literature on hunting."
Both Aristotle and Theophrastus have short accounts - probably based on the same source - of an ox-sized deer species, named tarandos, living in the land of the Bodines in Scythia, which was able to change the colour of its fur to obtain camouflage. The latter is probably a misunderstanding of the seasonal change in reindeer fur colour. The descriptions have been interpreted as being of reindeer living in the southern Ural Mountains in c. 350 BC
A deer-like animal described by Julius Caesar in his Commentarii de Bello Gallico (chapter 6.26) from the Hercynian Forest in the year 53 BC is most certainly to be interpreted as reindeer:
There is an ox shaped like a stag. In the middle of its forehead a single horn grows between its ears, taller and straighter than the animal horns with which we are familiar. At the top this horn spreads out like the palm of a hand or the branches of a tree. The females are of the same form as the males, and their horns are the same shape and size.
According to Olaus Magnus's Historia de Gentibus Septentrionalibus - printed in Rome in 1555 - Gustav I of Sweden sent 10 reindeer to Albert I, Duke of Prussia, in the year 1533. It may be these animals that Conrad Gessner had seen or heard of.
During World War II, the Soviet Army used reindeer as pack animals to transport food, ammunition and post from Murmansk to the Karelian front and bring wounded soldiers, pilots and equipment back to the base. About 6,000 reindeer and more than 1,000 reindeer herders were part of the operation. Most herders were Nenets, who were mobilized from the Nenets Autonomous Okrug, but reindeer herders from Murmansk, Arkhangelsk and Komi also participated.
Santa Claus' reindeer
Around the world, public interest in reindeer peaks in the Christmas period. According to folklore, Santa Claus's sleigh is pulled by flying reindeer. These were first named in the 1823 poem "A Visit from St. Nicholas", where they are called Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder, and Blixem. Dunder was later changed to Donder and--in other works--Donner (in German, "thunder"), and Blixem was later changed to Bliksem, then Blitzen (blitz being German for "lightning"). Some consider Rudolph as part of the group as well, though he was not part of the original named work referenced previously. Rudolph was added by Robert L. May in 1939 as "Rudolph the Red-Nosed Reindeer".
In mythology and art
Among the Inuit, there is a story of the origin of the caribou,
Once upon a time there were no caribou on the earth. But there was a man who wished for caribou, and he cut a hole deep in the ground, and up this hole came caribou, many caribou. The caribou came pouring out, until the earth was almost covered with them. And when the man thought there were caribou enough for mankind, he closed up the hole again. Thus the caribou came up on earth.
Inuit artists from the barren lands, incorporate depictions of caribou--and items made from caribou antler and skin-- in carvings, drawings, prints and sculpture.
Contemporary Canadian artist Brian Jungen's, of Dunne-za First Nations ancestry, commissioned installation entitled "The ghosts on top of my head" (2010-11) in Banff, Alberta, depicts the antlers of caribou, elk and moose.
I remember a story my Uncle Jack told me - a Dunne-Za creation story about how animals once ruled the earth and were ten times their size and that got me thinking about scale and using the idea of the antler, which is a thing that everyone is scared of, and making it into something more approachable and abstract.
Tomson Highway, CM is a Canadian and Cree playwright, novelist, and children's author, who was born in a remote area north of Brochet, Manitoba. His father, Joe Highway, was a caribou hunter. His 2001 children's book entitled Caribou Song/atíhko níkamon was selected as one of the "Top 10 Children's Books" by the Canadian newspaper The Globe and Mail. The young protagonists of Caribou Song, like Tomson himself, followed the caribou herd with their families.
Heraldry and symbols
Several Norwegian municipalities have one or more reindeer depicted in their coats-of-arms: Eidfjord, Porsanger, Rendalen, Tromsø, Vadsø, and Vågå. The historic province of Västerbotten in Sweden has a reindeer in its coat of arms. The present Västerbotten County has very different borders and uses the reindeer combined with other symbols in its coat-of-arms. The city of Piteå also has a reindeer. The logo for Umeå University features three reindeer.
The Canadian 25-cent coin, or "quarter" features a depiction of a caribou on one face. The caribou is the official provincial animal of Newfoundland and Labrador, Canada, and appears on the coat of arms of Nunavut. A caribou statue was erected at the center of the Beaumont-Hamel Newfoundland Memorial, marking the spot in France where hundreds of soldiers from Newfoundland were killed and wounded in the First World War and there is a replica in Bowring Park, in St. John's, Newfoundland's capital city.
Two municipalities in Finland have reindeer motifs in their coats-of-arms: Kuusamo has a running reindeer and Inari a fish with reindeer antlers.
