Take Action

Stand Up for National Monuments

Send comments to the Department of Interior today!

On April 26, President Trump signed an executive order directing the Department of Interior to review the designations of all monuments founded since 1996. The review could open millions of acres of national monuments to industrial development or even rescind such designations altogether—a move no previous president has ever attempted.

The Department of Interior has begun their review and is seeking public comment. We need your help to ensure the continued preservation of these spectacular landscapes.

Here’s what you can do right now:

  1. Visit: https://www.regulations.gov/comment?D=DOI-2017-0002-0001 and leave a comment telling the government to maintain protections for existing national monument designations.
  2. Share this action alert with your friends, family and colleagues.

Thanks for doing your part to protect our public lands legacy!
