This National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) Project Grant award of $202,001 to Northern Arizona University (NAU) supports collaborative research on the integration of plant-soil feedbacks with resilience theory for pinon woodlands under drought. The key objectives are to: Determine the degree to which recovery of pinon pine seedlings in drought-affected areas hinges on beneficial soil microbes, particularly ectomycorrhizal fungi, through field inoculations and laboratory assays. Investigate the threshold level of drought that degrades the resilience conferred by plant-soil feedback mechanisms, using a greenhouse experiment across the geographic range of pinon pine. This research aims to develop new methods to restore pinon trees in areas devastated by severe drought, which is causing widespread tree mortality across the western U.S. The findings are expected to broadly inform management of other drought-impacted forests by advancing the understanding of how soil microbes sustain terrestrial ecosystem resilience. The award period is from May 1, 2025 to April 30, 2029.
