Moose in trouble

North American moose populations are in alarming decline, and the causes are still unclear, though climate change has been identified as one likely culprit.

In Minnesota, for instance, one population of moose has declined from 4,000 to fewer than 100 since the 1990s, according to The New York Times. A second group of moose, in the northeastern part of the state—currently down to fewer than 3,000—has of late been reducing in numbers by 25 percent per year.

New Hampshire and Montana, and the Canadian province of British Columbia, have been experiencing similar declines.

Heat stress and an increase in ticks due to shorter winters are a couple of the major factors implicated in the die-off.
