Editorial. Improving our knowledge of drought-induced forest mortality through experiments, observations, and modeling

In this piece introducing the New Phytologist 'Drought-induced Forest Mortality' Feature Issue, we present some recent advances in forest mortality research. But first we highlight two notable challenges to this field: the dichotomy of drought vs pest- and pathogen-killed trees, and the trade-offs associated with doing laboratory studies on small plants vs field studies on mature trees.
