Aspens Remember Past Droughts, Three-Year Study Finds
Original: Aspens 'remember' past drought in their leaves, 3-year experiment finds
A three-year experiment shows that aspen trees retain a form of physiological memory of past droughts, visible in their leaves. Trees that experienced dry conditions earlier responded differently to later stress than those that had not, suggesting past climate events shape how these trees cope with future droughts. The findings could matter for predicting forest resilience as droughts become more frequent.
Why now: New research on drought memory in trees is timely given growing concern over climate change and forest health.
