ONDA is a 1,600-member, grassroots organization committed to protecting, defending, and restoring the health of Oregon's native deserts for present and future generations.  Founded in 1987, ONDA is the only group working exclusively to protect Oregon's vast High Desert. Over the past 20 years, ONDA has earned many successes including the protection of Steens Mountain as the nation's first "cow-free" Wilderness in 2000, and the removal of livestock from both the Hart Mountain National Wildlife Refuge and the Wild and Scenic Owyhee River. In 2009 ONDA was instrumental in the designation of the Badlands and Spring Basin Wilderness Area, creating 40,000 acres of new desert wilderness.
