Project A3-1 looks to better understand how plants and vegetation influence the tradeoff between provisioning of ecosystem services and use of water resources. We explore components of plant density and diversity as key components of the vegetation-hydrology nexus. Key ecosystem services we look to evaluate are climate cooling and well-being of urban residents.
We are using combinations of field surveys, embedded environmental sensors, and remotely sensed imagery of the urban environment. In a recent example of this work we linked field measurements of evaporation with a tower mounted on a trailer with satellite based imagery of vegetation to generate a whole-city map of evaporation.
In 2017 and 2018, we are deploying more than 300 air temperature sensors throughout eight metropolitan areas that represent the breadth of different climates within the United States. On the ground, we are surveying the biodiversity of green infrastructure throughout the United States to compare both types of green infrastructure and regions. This work is looking to assess how biodiversity influences the functioning and sustainability of green infrastructure projects. Together these tools will help evaluate how outdoor water use contributes to urban sustainability and resilience to environmental changes. We are exploring both vegetation writ-large within the urban environment and green infrastructure in particular.
Our work will help develop assessments of vegetation distributions to improve human well-being in the context of urban warming and drought. We will look toward identifying plant communities that maximize water use efficiency in supplying urban ecosystem services. People will benefit through better assessments of the water use by vegetation and the services provided by vegetation to better manage their landscapes.
Our project will generate new data that quantify both distributions of urban vegetation and the microclimate influence of vegetation across the UWIN network of cities.

Our research emphasizes questions that have strong theoretical implications for how biological systems work across multiple scales and directs application towards overcoming sustainability challenges. Most of our work uses sensor technology, remote sensing, field surveys, and numerical modeling techniques to generate multiple lines of evidence in answering questions. Our research has generally focused on the relationships between the carbon cycling, hydrologic cycling, energy partitioning, and biodiversity in dryland ecosystems across a diversity of land uses. We have explored these relationships both in terms of understanding carbon cycle responses to precipitation variability, and the role of vegetation for mitigating urban heat islands, and trade-offs in ecosystem services from high temperature agriculture. Together we aim to understand interacting sustainability trade-offs associated with natural, urban, and agricultural ecosystems across regional landscapes. Much of my work is collaborative and I value opportunities to work with researchers from other disciplines, institutions, and nations. I also like to analyze data for as many uninterrupted hours as possible.
