Title: Where less is more: Limited subsurface water storage capacity can shield forests from drought
Abstract: In upland landscapes, rock uplift and surface erosion create a structured critical zone, defined as the hydrologically active near surface layer that extends from the vegetation canopy down to underlying fresh bedrock. How does the structure of the critical zone – especially below soils and into saprolite and weathered rock – control water storage and release to ecosystems? In this talk, I present a synthesis of observational and modeling results from sites across California to address this question. I demonstrate how ecohydrological signals, such as annual plant water use and streamflow, reflect hydrogeological properties of the critical zone. Results highlight how, in addition to plant physiology and climate, the subsurface is a key regulator of ecosystem productivity, stream water availability, and forest response to drought.
