Data

National DWM field data (actual measurement variables without population estimates) are currently available at this location as comma delimited files.

http://www.fia.fs.fed.us/tools-data/data/.  FIADB snapshot download files for selected states are available at: http://www.ncrs2.fs.fed.us/FIADatamart/fiadatamart.aspx

The field data is organized according to a national data management standard (NIMS) that describes each table and field in adequate detail for interpretation and analysis. 

Download the document detailing DWM data structures. (pdf 280K)

Both population and plot-level DWM attributes estimates (e.g., fuel loadings) will be available in the near future as the programming of a national estimation engine is currently underway.  Stay tuned for more information!
