Massive Conifer Mortality

Report at LANL

Ecohydrology Group

The hydrological and ecological consequences of rapid changes in climate and the global hydrological cycle are staggering. Widepsread and severe drought, massive mortaility of forests, and declining water available for growing food and producing fibre are just some of the consequences. We seek mechanistic understanding of these dynamics by looking through the lens of plant hydraulics, which describes water flow from the soil to the atmosphere through plant xylem, and in turn is a vital pathway for nutrient, carbon, and energy exchanges. We examine these mechanisms by combining empiricism, mathematical models, and data analytics.
