Climate change is outpacing tree migration, causing species to retreat from hot, dry areas without expanding into cooler zones. A new study warns that without human intervention, many trees may struggle to survive. Assisted migration—relocating species to suitable climates—could be key to preserving forests in a rapidly changing world.

As climate change accelerates, many trees can't migrate fast enough to survive. Assisted tree migration helps species move to suitable climates, preventing forest decline. By strategically relocating trees, scientists and foresters aim to protect biodiversity and maintain ecosystems in a rapidly changing world. But is this intervention truly sustainable?
