vegetation invasion

Vegetation around the world is on the move, and climate change is the culprit, according to a new analysis of global vegetation shifts led by a University of California, Berkeley, ecologist in collaboration with researchers from the U.S. Department of Agriculture Forest Service.

In a paper published today in the journal Global Ecology and Biogeography, researchers present evidence that over the past century, vegetation has been gradually moving toward the poles and up mountain slopes, where temperatures are cooler, as well as toward the equator, where rainfall is greater.

“Approximately one billion people now live in areas that are highly to very highly vulnerable to future vegetation shifts,” said Gonzalez. “Ecosystems provide important services to people, so we must reduce the emissions that cause climate change, then adapt to major changes that might occur.”
