Natural Resource Inventory & Assessment System
Welcome to the Louisiana Department of Natural Resources, Atchafalaya Basin
Program's Natural Resource Inventory & Assessment System (NRIAS).
NRIAS was approved and funded through LDNR, ABP Fiscal Year 2010 Annual Plan process, by CPRA and with a
cooperative agreement with the USGS for web services.
The NRIAS is intended to provide a means for anyone to access information on current efforts to
enhance the Atchafalaya Basin, our nation’s largest river swamp.
Home to some of Louisiana’s signature wildlife – alligators, roseate spoonbills, water moccasins
and crawfish, to name a few – and spectacular views of the intersection of plant life, animal life,
water and weather, the Atchafalaya Basin has long called to fishermen, photographers, hunters and
those who simply enjoy the sights, sounds and smells of nature.
As the river’s flow has marked the generations, people have made different aspects of what is now
the Atchafalaya Basin spillway part of their heritage, from the Native Americans who made their homes
there to the loggers and fisherman who used the natural riches of the basin to make their
livelihoods.
