National Resources Inventory
The National Resources Inventory (NRI) is a statistically based sample of
land use and natural resource conditions and trends on U.S. nonfederal lands. It
is the most comprehensive database of its kind ever attempted anywhere in the
world.
Data for the NRI are collected at more than 3,000 locations in Arizona by
NRCS resources inventory specialists at the Inventory Collection and
Coordination Site in Phoenix, Arizona.
