We have to be great stewards of this land. This is magnificent land." -- President Donald Trump

The U.S. Department of the Interior touches more American lives in more ways than any other federal agency -- managing one-fifth of the land in the United States including our national parks, wildlife refuges, and the delivery of water and power in the West. 

As the stewards of this public trust, the Department manages America’s public lands for multiple uses, ensuring these lands are available for recreation, job growth and creation, and responsible energy development, following in the example set forth by President Theodore Roosevelt, who said:

"We have fallen heirs to the most glorious heritage a people ever received, and each one must do his part if we wish to show that the nation is worthy of its good fortune."

The Department, under Secretary Zinke’s leadership and guidance, will continue to fulfill this mission so that generations to come may enjoy the diversity of our lands that are uniquely American.
