Climate impacts drive east-west divide in forest seed production

Younger, smaller trees that comprise much of North America's eastern forests have increased their seed production under climate change. But older, larger trees that dominate western forests have been less responsive, a new study warns. This continental divide could limit western forests' ability to regenerate following large-scale diebacks linked to rising temperatures and intensifying droughts. Over time this might dramatically alter the composition and structure of 21st century North American forests.
