Reindeer Numbers Have Fallen by More than Half in 2 Decades
It's a sad Christmas for the world's reindeer—the antlered Arctic grazers associated with all things Santa Claus. Their numbers have fallen by more than half in the past 20 years, and climate change is likely to blame.
The latest numbers come from the National Oceanic and Atmospheric Administration's 2018 Arctic Report Card, which listed the increasing impacts of global warming on the earth's northernmost region, as EcoWatch has already reported. But the loss of Rangifer tarandus—called caribou in North America and Greenland and reindeer in Siberia and Europe—is of note because it threatens to further throw Arctic ecosystems and cultures out of whack. Reindeer are important prey for wolves and biting flies, and a key source of food and clothing for indigenous groups.
"If you look at the [top] Northern resources, that shape the culture of northern communities and aboriginal people, what they have in common is caribou and or wild reindeer, no matter where they are in the circumpolar North," Don Russell, lead author of the Report Card's essay on reindeer, told Vox.

The report found that reindeer and caribou herds have declined by 56 percent in the past two decades—that's a decrease of 2.6 million reindeer from a population of 4.7 million to a population of 2.1 million. Five herds in Alaska and Canada were particularly at risk: their populations have declined by more than 90 percent and showed no signs of rebounding. While it is normal for caribou and reindeer herds to swell and shrink, some herds are at all-time lows since record-keeping began.
"The fact that these herds are declining shouldn't be a shock—they do it all the time," Russell told Vox. "But they're at such low levels, you start to be concerned ... If we return in 10 years and [their numbers] have gone down further, that would be unprecedented."

Scientists don't know exactly what is causing the decline in herd numbers, but it is likely a variety of climate-linked factors caused by warmer summers and winters.
- Food Shortage: Caribou subsist on lichen, which grows on the ground. But warmer temperatures encourage taller plants to grow. "Warming means other, taller vegetation is growing and the lichen are being out-competed," University of Virginia environmental science professor Howard Epstein, who helped with the research behind the report, told BBC News.
- Bug Off: Warmer weather also means more insects. The caribou then spend their energy hiding from them or fending them off, instead of looking for food. "It's said that a nice day for people is a lousy day for caribou," Epstein told BBC News.
- Rainy Days: Warmer winters, on the other hand, mean more rain falls than snow. The rain then freezes into a layer of ice that the reindeer cannot break through to reach food, BBC News explained. In one incident in 2013, ice cover in Russia meant that 61,000 reindeer starved to death, Vox reported.

These factors have been shown to impact individual herds. Warmer Julys and freezing rain from September to December were shown to explain 64 percent of the variability in adult caribou cow survival in the herd in Bathurst, Canada, the report said.

This week marks the official start of fall, but longer nights and colder days can make it harder to spend time outdoors. Luckily, there are several inspiring environmental films that can be streamed at home.

"This is why I got involved."</p>

"Sadly, these lands that belong to you and me are under unprecedented threats from the greed of big corporations, eager to weaken restrictions in the pursuit of profits. Many of our current politicians are also to blame. <em>Public Trust</em> tells the story of citizens who are fighting back. It's a much-needed wake-up call for all of us who want to preserve our unique and wild cultural heritage."</p>

If all the glaciers and ice caps on the planet melted, global sea level would rise by about 230 feet.
