How do conifers survive droughts? Study points to existing roots, not new growth: Scientists can't see underground, but computational models are providing a new way to investigate how root systems might be changing

As the world warms, a new study is helping scientists understand how coniferous forests may respond to drought. The research addresses a classic question in the field: When conditions are dry for long periods of time, do trees survive by growing new roots to tap water sources, or by relying on established roots that already go deep?
