Federal Project Grant Award Summary

The National Science Foundation (NSF) Division of Environmental Biology awarded Columbia University $327,495 under the Biological Sciences program (CFDA 47.074) for a collaborative research initiative examining how natural environmental variability affects tree growth across the United States. The project, which commenced September 1, 2026, and runs through August 31, 2031, develops improved predictive models for forest productivity responses to short-term meteorological fluctuations in water availability and temperature. Primary deliverables include mechanistic understanding of tree growth responses at daily to seasonal timescales, validated through high-sensitivity automated point dendrometers deployed across multiple sites via the National Ecological Observatory Network (NEON), along with publicly accessible above- and below-ground tree growth datasets spanning intra-annual temporal scales.

The research output directly supports science-based forest management decision-making to enhance forest health, sustain rural economies, and ensure long-term resource sustainability. The award includes substantial educational components, providing undergraduate students, graduate students, and K-12 teachers with hands-on learning experiences in forest ecology and tree physiology. By integrating fine-scale daily to monthly growth observations with continental-scale forest diversity analysis, the project advances understanding of how individual tree growth mechanics translate across varied forest types and climatic regions in the United States.
