_“As the Nation’s principal conservation agency, the Department of the

Interior has basic responsibilities for water, fish, wildlife, mineral,

land, park, and recreational resources. Indian and Territorial affairs

are other major concerns of America’s Department of Natural Resources.”

The Department works to assure the wisest choice in managing all our

resources so each will make its full contribution to a better United

States—now and in the future._
