Abstract

ASU.tague2.001.jpg

One of the goals of eco-hydrology is to be able to estimate how much water plants use.  Plant water use often comprises a substantial fraction of the water budget, influencing water flux to the atmosphere, recharge to groundwater and surface water. At the same time how much water plants are able to access is often a key control on plant growth, carbon sequestration and vulnerability to pathogens, insects and fire.  Eco-hydrology investigates how plant water use changes with climate, and the effects of planned and unintentional changes to the landscape through disturbance, land management practices and development. In recent decades, a multiplicity of techniques have been used to improved estimates of plant water use ranging from tree-scale measurements to flux tower measurements of stand-scale behavior to regional/global scale remote sensing. Process-based models provide a complementary approach that can be used to guide, explain and synthesize these measurements. This talk will demonstrate this often under-utilized role of process-based models. Using case-studies from the Western-US, I will show how model-data integration can provide insight into how warmer temperatures and drought influence forest water use and vulnerability to drought-related disturbance and whether forest management practices can mitigate this vulnerability. Results emphasize the utility of new geophysical data collection at multi-PI observatories (such as the Critical Zone Observatory Network and Long-Term Ecological Research Sites) and the importance of new informatics tools that support the evolution of environmental information systems.

Heckman part of Graduate Research Advocacy Day

Tague Team Lab PhD student Chris Heckman participated in Graduate Research Advocacy Day in Sacramento on March 16th, 2016. Chris was selected as a UCSB advocate to educate lawmakers about the importance of graduate research and its contribution to California’s economy and progress. Chris was able present his research on “Managing forests in an era of drought” and tell lawmakers about his work using a computer model to research how the vast variability in soil water storage across the Sierra Nevada will affect vegetation response to climate change, and how his studies will help forest managers design a more balanced approach to conserving forest health and downstream water supplies into the future.
