The 2000-2003 drought in the American southwest triggered a widespread die-off of forests around the region. A team of scientists developed a new modeling tool to explain how and where trembling aspen forests died as a result of this drought, based on damage to the individual trees’ ability to transport water. Their results suggest that more widespread die-offs of aspen forests triggered by climate change are likely by the 2050s.
