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 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2029.

Abstract

In terrestrial plant communities, woody plants are overtaking their herbaceous (non-woody) relatives. This is happening in plant communities globaly. In tundra ecosystems, the environmental causes of this have been studied extensively, but less is known about the potential influence of biologically-influenced interactions on woody plant abundance and growth rates. This project evaluates the extent to which…
