Here are the national monuments being reviewed under Trump’s order

Share via

President Trump signed an executive order in April calling for Interior Secretary Ryan Zinke to review national monuments created by Presidents Clinton, George W. Bush and Obama. These monuments were set aside as public land under the 1906 Antiquities Act, which gives presidents the power to limit use of public land for historic, cultural, scientific or other reasons.

In advance of the signing ceremony, Zinke said the order would apply only to monuments created since Jan. 1, 1996, that are at least 100,000 acres.

Here are the national monuments listed by the White House as being under review.

Established Dec. 28, 2016: The 1.3-million-acre Bears Ears National Monument in the remote desert canyonlands of southern Utah was designated by President Obama, who created more national monuments than any other president. The Bears Ears designation angered Republican politicians in Utah, who want the land available for possible gas, oil and mining use -- and who directed Trump’s attention to the issue of national monuments. He said that the Bears Ears designation “never should have happened” and that it was part of “this massive federal land grab that’s gotten worse and worse and worse.”
