A reindeer census on the island of Spitsbergen in Norway has revealed some surprising statistics. The Svalbard reindeer population has experienced its largest growth spurt yet, say researchers who have been counting the animals annually since 1979. This year, they recorded 1300 reindeer alone—a 30% jump from 2013, National Geographic reports. While temperatures have been rising in the Arctic region for years, the Svalbard reindeer seem to be doing just fine. The scientists suspect it’s because the plants they consume are available for longer periods now because of warming temperatures.
