Forest inventory and analysis tree-ring data archive and analysis

January, 2011

The Interior West Forest Inventory and Analysis (FIA) Program collects increment cores as part of regular monitoring. Ring-widths from these increment cores are being digitized and assembled into data products for biogeographical or climatological analyses. 

In the Interior West states, FIA collects increment cores on most forested plots. These include cores from the periodic inventories (late 1980s to early 2000s) and from the current annual inventory system in some states. A long-term project was initiated with the goal of digitizing ring-widths from the increment cores, which can be assembled into gridded data products and used for any number of potential analyses.

The project status is active and ongoing, as there are tens-of-thousands of increment cores to process.
