Across the U.S., volunteers are hiking into the woods to observe two species of trees — the Balsam Poplar and Quaking Aspen. These citizen scientists monitor the trees throughout the year and share their observations with researchers.
That’s Andrew Elmore of the University of Maryland Center for Environmental Science. He says that all trees within a species are not the same. By learning how Poplar and Aspen differ by region, and the genetic basis for that diversity, researchers can predict how the trees will respond to rapid climate change.
Elmore: “They might migrate. They might adapt as a species, meaning their population structure might change over time. Or they might just go extinct.”
Knowing which trees can or cannot withstand warmer temperatures could help conservationists prioritize their efforts to save the species. Options include preserving areas with well-adapted trees and transplanting cold-loving varieties as their habitat moves further north.
