Trees in the Brazilian Atlantic Forest are migrating in search of more favorable temperatures, with species in mountain forests moving uphill to escape rising heat caused by climate change, a new study reveals. Most species in higher parts of the Brazilian Atlantic Forest are moving upwards as temperatures rise, but scientists say that those trees which thrive in colder temperatures are at risk of dying out as the world continues to warm. Researchers studying the forest, which stretches along Brazil’s Atlantic seaboard, have also discovered that some trees in lowland forests are migrating downhill. …The researchers studied 627 tree species across 96 different locations across the Brazilian Atlantic Forest to calculate community temperature scores —a means of understanding climate patterns across the Forest. Researchers also discovered that younger trees in high-altitude forests are moving uphill—young tree groups had more growth than the older ones, and this growth had increased over a decade of observing the forest.
