A research team led by Geography, Environment, and Planning Professor Matthew Clark in the Center for Interdisciplinary Geospatial Analysis (CIGA), in collaboration with researchers in Sonoma State's Biology Department and University of Oxford Environmental Change Institute, recently published a paper, "The Potential of Multispectral Imagery and 3D Point Clouds from Unoccupied Aerial Systems (UAS) for Monitoring Forest Structure and the Impacts of Wildfire in Mediterranean-Climate Forests", that investigated how unoccupied aerial systems (UAS, or drones) can be used for monitoring changes in 3-dimensional forest structure, such as tree height, after fires. This research is based at the Pepperwood Preserve in Santa Rosa and used a drone that looks like a small airplane to explore forest recovery after the Tubbs fire in 2017. Drone data were collected and processed by graduated CIGA interns Corbin Matley and Elise Piazza. This research is funded by grants from CAL FIRE and the CSU Agricultural Resource Institute.
