Олені свальбарду взимку мають проблеми з доступом до їжі що закрита льодом
Reindeer need from 4 to 8 kg of food a day. They are herbivorous, so their diet consists mainly of grasses, mosses, herbs, ferns, shrubs, willows, and, during the winter months, lichen and fungi.
It is hard for Svalbard reindeer to reach food in winter, as it is often buried under sheets of ice and snow. For that reason, they spend much of their time kicking holes in the snow.
It’s exhausting work, but once they reach food they graze and then lie down to chew and ruminate. This is why one often sees reindeer chewing. As ruminants, they regurgitate cud, partially digested food, to break it down and facilitate digestion.
