This is a $889,987.00 cooperative agreement awarded by NASA's Shared Services Center to Northern Arizona University (NAU) to investigate vegetation dynamics in the Arctic and boreal regions using satellite data, airborne sensors, and field measurements. The research aims to document changes in vegetation productivity and assess the progression of an Arctic-boreal biome shift, where tree productivity decreases and woody vegetation expands northward. NAU, a public research university and Hispanic-serving institution, has extensive experience supporting federal agencies through research and technical assistance contracts and grants, including work for NASA, USGS, IHS, DoD, and NPS. This award does not have a set-aside designation, reflecting NAU's competitiveness as a research institution. The university leverages its expertise in environmental sciences, forestry, and Native American studies to address critical scientific and societal challenges through collaborations with other academic and tribal partners.
