In fast-warming Minnesota, scientists are trying to plant the forests of the future

MINNESOTA — Almost everywhere he looks, Lee Frelich sees the fingerprints of climate change on the forests he has studied since he was a boy half a century ago.

Birds from southern Minnesota are now popping up far north in Ely, on the edge of the famous Boundary Waters Canoe Area Wilderness. Splashes of red maple leaves are now visible each fall amid the pines and spruces of the iconic North Woods, where they once would have been harder to find.<
