The National Science Foundation Division of Environmental Biology awarded American University a $215,146 Project Grant under the Biological Sciences federal grant program (CFDA 47.074) beginning January 1, 2023 through December 31, 2025.

The award will support collaborative research to better understand the role of trees in the global water and methane cycles. Specifically, the grantee will measure radon, methane, and water fluxes from trees across a wetland-upland gradient to determine if methane emitted from trees originates from soil water or is produced within the tree. Concurrent measurements of soil moisture, water potential, gas concentrations, water table height, and tree physiology will be taken to model dynamic gas transport through the soil-plant-atmosphere system. Additionally, around 200 elementary students will participate in hands-on science activities at American University focused on watersheds, trees and sustainability. Findings will help improve climate predictions and forest management strategies to reduce natural methane emissions.
