Winter ticks threaten New England moose
Warmer winters are imperiling New England moose as winter tick numbers swell, resulting in an unprecedented die-off of moose calves. In a study led by TWS member Peter Pekins, researchers counted an average of 47,371 winter ticks on calves. Most adults survived the infestation but were severely compromised. Calves experienced a 70 percent death rate between 2014 and 2016. Researchers say the increase in winter ticks is due to warmer winters and longer warm periods in the spring and fall.
