RESEARCH
South Cumberland Plateau
Dr. Powell is a principal investigator of the Split Creek Observatory, an instrumented 50-ha watershed located in Sewanee's forest on top of the plateau. This research site integrates the study of the biological, physical, chemical, hydrological, and geological processes in the critical zone of Earth's crust that regulates and sustains life. Dr. Powell studies how the different tree species and the forest function are influenced by topographic position (ridges vs. depressions) and environmental variation (rainfall and temperature).

Rocky Mountain Subalpine Forests
In collaboration with colleagues at UC-Berkeley, Berkeley National Lab, UI-Chicago, and Oregon State, Dr. Powell studies how climate change and pests impact the stability of subalpine forests in different topographic positions in the Colorado Rocky Mountains. Subalpine forests are critical for regulating the supply of water to the Colorado River.
