Roy Petrakis work for the Western Geographic Science Center and is located in Tucson, AZ.

I am a Geographer with the U.S. Geological Survey - Western Geographic Science Center in Tucson, AZ. I am a team member for both the Tribal Land Vegetation and Watershed Modeling and Aridland Water Harvesting Study teams. My research often addresses themes such as wildfire and fuel treatments, climate variability and drought, surface water, watershed management, land use/land cover, and riparian ecosystems, among others, using remote sensing and GIS applications and methodologies.

In my time with the USGS, I have published on topics including the use of fuel treatments in reducing wildland fire severity, mapping surface water trends on a national scale, and assessing riparian vegetation response to changing climate conditions to inform Tribal restoration priorities.
