There are currently 63 National Parks in the United States: https://en.wikipedia.org/wiki/List_of_national_parks_of_the_United_States

Will any of these Parks have land area sold, redesignated as National Forest, National Monument, etc., or otherwise cease to be a part of the National Park they are currently a part of as of March 4 2025?

This would count if an entire Park is removed as well. Any such action will count until the term is over, i.e. until inauguration in January 2029. This action must hold until that date. If such an action has been taken but is held up in courts and may be reversed, I will poll Manifold on how likely the action is to be upheld and resolve to that percentage.
