Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 December 2026.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 30 April 2027.

Abstract

Fire is an Earth system process with both vegetation and atmospheric feedbacks. Grass-fueled fires in savannas currently dominate global burned area, but grazers potentially eat enough grass to suppress fires at the landscape scale. How these processes affect global biogeochemical cycles is not quantitatively understood. This project combines present-day experiments and observations with paleoecological observations…
