The Antiquities Act of 1906 is one of the most important tools available for the preservation of public, federal lands and historical sites for all Americans to enjoy.

On April 26, 2017 President Trump signed an executive order directing the Interior Department to conduct a review of approximately 25 national monuments, going back to 1996 designations, to recommend potential changes. This order targets the Antiquities Act, which permits presidents to declare federal lands, already owned by all Americans, as monuments in order to protect their historical, cultural or scientific value and overall national significance.

The law is essential to maintain the integrity of critical national and cultural resources including:

For over one hundred years the Antiquities Act has been used as a bi-partisan conservation tool. With the exception of the Organic Act of 1916, no law has had more influence over the development of the modern National Park System and our other public lands than the Antiquities Act. NPCA is opposed to proposals that would restrict presidential authority to proclaim national monuments.
