The Department of the Interior, created in 1849, is our Nation's De- 

 partment of Natural Resources, concerned with management, conserva- 

 tion, and development of water, wildlife, fish, mineral, forest, and park 

 and recreational resources. It also has major responsibilities for Indian 

 and Territorial affairs. 



As America's principal conservation agency, the Department works to 

 assure that nonrenewable resources are developed and used wisely, that 

 park and recreational resources are conserved for the future, and that 

 renewable resources make their full contribution to the progress, pros- 

 perity, and security of the United States, now and in the future.
