This $171,554 Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) supports collaborative research to quantify the amount and functional significance of long-term stored water in trees. The investigators will measure water storage in different tree organs, determine water residence times, and evaluate how stored water affects whole-tree water use. Data collected will reveal novel information about tree water storage and management to allow prediction of storage and movement under current and future climates. Results will be shared with communities in the Snake River Plain region of Idaho, involving students and faculty from tribal colleges in the Pacific Northwest. The award recipient is Duke University for work performed in Durham, North Carolina, reflecting NSF's mission to promote biological sciences research and strengthen the national scientific enterprise.
