Ryan Zinke

WASHINGTON — Interior Secretary Ryan Zinke on Tuesday again called on President Donald Trump to shrink a total of four national monuments — including Southern Oregon’s Cascade-Siskiyou — and change the way 10 others are managed, a sweeping overhaul of how protected areas are maintained in the United States. …The Antiquities Act over time has done great things for our country, and it has protected some of our greatest treasures,” he said, adding that Trump was “absolutely right” to conduct the report because some of his predecessors had abused their authority. …Two groups, the Association of O&C Counties and the American Forest Resource Council, sued when then-President Barack Obama nearly doubled the monument’s size earlier this year.
