Unraveling the Mystery of Aspen Death: Research Explores Causes and Extent

Sudden aspen decline (SAD) is a phenomenon affecting Colorado's beloved aspen trees, characterized by rapid dieback and mortality. Scientists attribute SAD to a combination of factors, including acute warm drought, weakening the trees' ability to fight off insects and pathogens. As the world warms and drought intensifies, the underground root system responsible for nutrient supply to the canopy is compromised, depleting the trees' energy source. While aspen is known for its resilience and ability to regenerate, concerns remain about the impact of SAD on young sprouts and the need for land management strategies to support regeneration.
