Maine has the world's southernmost populations of Arctic charr, a landlocked fish left stranded here when the glaciers retreated. But the rare fish, once called blueback or Sunapee trout, are facing significant challenges, including a fast-warming climate. Although a warming climate poses risks to charr, their most immediate threat is the introduction of nonnative fish species. Bob Mallard, of the Native Fish Coalition, says in addition to the species that are introduced illegally, he’s worried about the state's practice of stocking lake trout in Hancock County's Green Lake, which is also home to Arctic charr.
