Maine is home to the largest moose population in the lower 48 states. But the iconic species is being challenged by ticks and climate change. In one of the moosiest parts of Maine, nearly 90 percent of the calves tracked by biologists last winter didn’t survive their first year.
Winter ticks, which are sometimes called moose ticks, have been pestering Maine moose for about a century and likely longer. But their numbers have exploded in parts of Maine, New Hampshire, Minnesota and southern Canada. It’s not uncommon for biologists or hunters to find moose infested with 40,000, 75,000 or even 90,000 ticks.
