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 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

The end of the last ice age and its transformation of North American ecosystems provides a natural experiment for studying how far species and ecosystems can move as environments change and a naturally engaging way to teach students about the history of their local landscapes. This project will employ state-of-the-art open databases of fossils and Earth system models to map past biome distributions in North America…
