A window of opportunity for climate-change adaptation: Easing tree mortality by reducing forest basal area
John B. Bradford, David M. Bell
2017, Frontiers in Ecology and the Environment (15) 11-17
Increasing aridity as a result of climate change is expected to exacerbate tree mortality. Reducing forest basal area – the cross-sectional area of tree stems within a given ground area – can decrease tree competition, which may reduce drought-induced tree mortality. However, neither the magnitude of expected mortality increases, nor...
