The Tague EcoHydrology lab focuses on watershed research, addressing the feedbacks among terrestrial vegetation, surface hydrological processes, and atmospheric conditions. We use a variety of techniques to examine the impact of changes in climate and land use on ecosystem health and water resources.
Please scroll through our blog below to see what we’ve been up to!
All are welcome to attend our weekly lab meetings and take part in presentations and scientific discussions. See our Lab meeting schedule & events page for information on each week’s topic or presenter. Meetings are held in the Bren hall lab wing, room 1005.
In this new publication, the authors conducted a large-scale thinning experiment in a semi-arid pine afforestation in the Yatir forest, located at the northern edge of the Negev desert, Israel. RHESSys was also used to upscale tree-scale measurements.

In this new publication, authors Gabrielle Boisrame, Sally Thompson, Naomi Tague, and Scott Stephens use RHESSys to look at the hydrologic response of a restored fire regime in a basin within Yosemite National Park, California.

Naomi Tague recently presented “Animating Green Stuff in Hydrologic Models: Where We Are and What Is Next?” at the Gordon Research Conference – Catchment Science: Interactions of Hydrology, Biology and Geochemistry, Transcending the Uniqueness of Place in the Age of Big Data, June 23-28 at Proctor Academy in Andover, NH.
In this new publication in Frontiers, authors Naomi (Christina) Tague and Max Moritz highlight the importance of accounting for site-specific variation, such as soil water storage capacity, in assessing how fuel treatments may interact with ecosystem water use and drought vulnerability, and ultimately downslope impacts on streamflow.

Congratulations to Tague Team PhD student William Burke on successfully defending his PhD thesis proposal “The Ecohydrology of Fuels Treatments”.
William is developing and will integrate a new multi-scale routing method into the RHESSys model – addressing limitations with current approaches – in order to better characterize and assess the effects of thinning methods on forests. Using this new method, he will assess how different thinning treatments and landscape characteristics interact and result in varying effects on forests, water, and fire.
In their new publication ” The changing water cycle: The eco‐hydrologic impacts of forest density reduction in Mediterranean (seasonally dry) regions“, authors Tague, Moritz, and Hanan, offer an eco‐hydrologic perspective that considers both how much water trees use (hydrology) but also how water availability affects forest ecophysiology and health (ecology). This eco‐hydrologic perspective helps to build a conceptual model of the mechanisms through which changes in forest structure and composition can influence water availability, forest productivity, and mortality patterns, particularly in Mediterranean‐climate regions, both during and after droughts.

Congratulations to Tague Team PhD student Chris Heckman on successfully defending his PhD thesis proposal “Forest resiliency through a sub-surface lens”.
Using the RHESSys model, Chris’s research explores how the vast variability in soil water storage across the Sierra Nevada will affect vegetation’s response to climate change.
Katalyn Voss, PhD candidate and TagueTeamLab friend, will this morning defend her PhD thesis “Contributions of Glacial Melt, Snowmelt, and Groundwater to Streamflow During Low-Flow Periods: A Paired Catchment Approach in the Arun Watershed, Eastern Nepal”. Naomi Tague is a member of her PhD committee.
9am 6th floor Ellison Hall – ERI conference room.
TagueTeamLab leader Naomi Tague and member Will Burke were advisors on the Bren MESM project for Team Citeplan, who spent the last year investigating the relationship between timber management, fire regimes, and wildfire behavior. Now, their findings and deliverables are being sent to a team of researchers at UC Berkeley and to officials at CAL FIRE where they will hopefully use Citeplan’s standardized approach for Wildfire Risk and Hazard assessment.
Congratulations to Bren MESM student team members Caitlin Swalec, Lauren Krohmer, Emma Siegfried, Laura Gray, and Courtney Schatzman on completing this project!
