While most of the world’s populations of reindeer and caribou have declined significantly in recent decades, Iceland’s herd is doing fine. Its population grew rapidly in recent decades and is now stable.
Reindeer were first brought by royal decree from Norway to Iceland in the 1700s after diseases had killed about 60 percent of the island’s sheep population. Initially there was hope they could be domesticated and be kept on farms. But early efforts at reindeer husbandry fizzled due to the harsh winters, competition with sheep farmers, and lack of interest among Icelanders in raising the animals.

The population swelled from a few dozen reindeer in the 1700s to more than 5,000 now.
