As tree species face decline, ‘assisted migration’ gains popularity in Pacific Northwest

As native trees in the Pacific Northwest die off due to climate changes, the U.S. Forest Service and others are turning to a strategy called “assisted migration.”

As the world’s climate warms, tree growing ranges in the Northern Hemisphere are predicted to move farther north and higher in elevation.

Trees, of course, can’t get up and walk to their new climatic homes. This is where assisted migration is supposed to lend a hand.
