Many species of trees, including strains of oaks and maple, are migrating westwards over time to escape environmental adversities, a trend that scientists consider worrisome, for its potential to upset forest ecosystems.

The field data obtained from the U.S. Forest Service shows that out of 86 species that moved across the eastern U.S. between 1980 and 2015, 73 percent migrated to the west, notes Popular Science.

The observation suggests that moisture-availability, a factor related to climate change, is a more dominant force in governing the magnitude and direction of a species response to environmental challenges than temperature, reports Science Daily.
