Steps

  1. Go to https://apps.fs.usda.gov/fia/datamart/ and open the CSV download page at .../CSV/datamart_csv.html
  2. Select the state(s) and table(s) needed (Plot, Tree, Condition, Population, Down Woody Material, Soils) and download the zipped CSVs, or grab a full state/national SQLite database file instead
  3. No authentication or API key is required; all files are public HTTP downloads
  4. Join downloaded tables to the REF_* reference tables and filter by EVALID before computing any estimate, since raw plot counts alone are not statistically valid
  5. For FVS-ready extracts, use the dedicated 'FVS input files' bulk download section on the same portal
