Forest Inventory and Analysis research units throughout the United States have participated in establishing a National Database Retrieval System. This database was established to provide common forest resource attributes using compatible formats in a standard set of inventory tables. Statewide data may be downloaded from this database in tabular format or as comma delimited text files. The text files have been made available from the most recent inventory of each state, and may be downloaded as either a tree file, plot file, or county file.
