The Svalbard reindeer (Rangifer tarandus platyrhynchus ) is a small subspecies of reindeer found on the Svalbard archipelago of Norway. They are the only large grazing mammal in the European High Arctic, and this makes them exceptional for studies concerning the introduction of pollutants to changing ecosystems. They are relatively sedentary, and are thus highly vulnerable to changes in local conditions.

starts withCompared to other reindeer, they are short-legged and have a small, rounded head. Their fur is also lighter in colour and thicker during winter. The thickness of the coat contributes to the short-legged appearance and makes even starved animals appear fat in the winter. The males develop large antlers during the period from April to July and shed the velvet during August–September. Males lose their antlers in early winter. Females develop antlers starting in June and they are usually retained for a whole year.
Males average 65–90 kg (143-198 lb) in weight, females 53–70 kg (116-154 lb), while for other reindeer generally body mass is 159–182 kg (350-400 lb) for males and 80–120 kg (176-264 lb) for females.
During the short Arctic summer, Svalbard reindeer feed on a lush tundra vegetation of vascular plants, including grasses, herbs, sedges and deciduous shrubs in the lowland plains and valleys, to accumulate fat for the winter. The fur of Svalbard Reindeer contains elements and chemicals picked up from the vegetation they digest.
Some 200 reindeer were found starved to death in July 2019. Rain on snow early in the winter season formed thick layers of ice on the tundra, making grazing plants inaccessible, a result of the warmer temperatures due to climate change.
By 1925 they had almost gone extinct due to over-hunting in the late nineteenth and early twentieth centuries. Over recent decades their population has increased. As of 2019 the total population across the archipelago is approximately 22,000.
