Trump reduced Bears Ears and Grand Staircase-Escalante national monuments in Utah by roughly 90%, cutting protections from 3 million acres down to 300,000. The move opens previously protected federal land to oil drilling and development — reversing protections established under Clinton (1996) and Obama (2016). Native American tribes and conservationists who consider these lands sacred have already signaled legal challenges, and the decision mirrors Trump's earlier 2017 monument reductions.
