Abstract

The unprecedented heatwave that hit the Pacific northwest of North America in late June14 early July 2021 impacted ecosystems and communities, yet evidence and analysis of this impact are still missing. Here we bring a unique dataset quantifying the impact on conifer trees, which are keystone species of many northwest ecosystems. Moreover, we take advantage of this exceptional event as a broad, extreme, “field experiment” to test a fundamental theory in plant physiology, and prepare our forests to a harsher future. Overall, the data collected confirm the role of hydraulic vulnerability in drought-induced injury to trees.
