President Donald Trump’s administration is moving to expand hunting, fishing and target shooting at as many U.S. national monuments as possible, under a plan signed Friday by Interior Secretary Ryan Zinke.

Limited hunting and shooting is already allowed at some monuments, but the new plan seeks to open monuments that have previously banned those activities, a step that drew criticism from environmentalists and praise from hunters.

Under Mr. Zinke’s order, hunting and target shooting could return to popular recreation areas such as the Dinosaur National Monument in Colorado, which now prohibits those sports.

Interior officials said details would be worked out by the various agencies managing federal lands. The order instructs those agencies to do what they can within their authority to expand hunting, fishing and shooting on the monuments they oversee.

Target shooting and hunting are prohibited at most of the 129 national monuments, while fishing is currently allowed at many of them.
