Archived Annual National Resources Inventory
For reference only, we are providing this archive of previous Annual National Resources Inventory
(NRI)
findings on topics for which the 2003 Annual NRI findings have not yet been
released.
The 2003 Annual NRI data replace previous annual inventory
data for analysis purposes. With each new inventory the estimates for the
previous inventory years are recalculated to reflect changes in inventory
technologies and protocols. This editing process ensures consistency for
trend analysis across all inventory years (1982, 1987, 1992, 1997, 2001, 2002,
2003).
