Join the call to create Oregon’s next national monument

The Antiquities Act is a 1906 law, passed by Congress, that grants U.S. Presidents the ability to designate federal lands and waters with scientific, historic, and/or cultural significance as national monuments with a presidential proclamation. Since President Teddy Roosevelt signed the Antiquities Act into law, 18 presidents, an equal number from both parties, have used the Act to designate or expand national monuments.

As the largest conservation opportunity in the American West, the colorful canyons, sweeping seas of sagebrush steppe, rambling rivers and snaking streams of the Owyhee Canyonlands provides habitat for more than 200 species of wildlife, including the imperiled Greater sage grouse, pronghorn antelope and one of the largest herds of California Bighorn sheep. The region boasts almost 30 plant species that are found nowhere else in the world and scientists even say it may become one of the last few places to view the night sky in the lower 48 without light pollution. With the Owyhee Canyonlands, we have the opportunity to manage and preserve an expansive, intact natural wonder before it suffers irreparable damage and degradation.

You can help convince the Biden Administration to permanently protect this spectacular landscape by urging Sens. Wyden and Merkley to support President Biden in establishing an Owyhee Canyonlands National Monument before the end of 2024.
