Moose Population in Decline

The New York Times reports that across North America, moose populations are in decline and scientists are unsure why. But most hypothesize that climate change is part of the reason. Winters have grown shorter across the moose’s range, causing parasites to attack.  For example, in New Hampshire, a longer autumn and less snow has increased the number of winter ticks, which are devastating to moose.  Another theory is that the decline is due to heat stress as moose, which are made for cold weather, strive to stay cool among warmer winter temperatures. The decline in moose has more than just environmental impacts.  Moose contribute to the economy, too. In New Hampshire, moose-watching tourism is a $115 million-a-year business.
