Proclamation 9564

Boundary Enlargement of the Cascade-Siskiyou National Monument

President Obama used the Antiquities Act to expand the Cascade-Siskiyou National Monument by approximately 48,000 acres in Oregon and California, adding ecologically significant lands including Horseshoe Ranch, Jenny Creek watershed, and Grizzly Peak area to protect biodiversity, habitat connectivity, and historic resources. The proclamation withdraws these federal lands from entry, mining, and mineral leasing, and directs the Secretary of the Interior to manage the expansion through the Bureau of Land Management.

Who is ordered

Timeline

Immediate

  • Monument boundary expansion takes effect upon proclamation
  • Federal lands withdrawn from entry, location, sale, mining, and mineral/geothermal leasing
  • Management authority transfers to BLM under National Landscape Conservation System

Near term (90d)

  • Secretary of Interior may develop travel management plan for snowmobile and non-motorized mechanized use

Long term

  • Ongoing scientific research and conservation of expanded habitat connectivity corridors
  • Potential future federal acquisition of non-federal lands within boundaries automatically reserves them into monument

Risks & tensions

  • Expansion may face legal challenges regarding 'smallest area compatible' requirement of Antiquities Act
  • Withdrawal of lands from mining and mineral leasing restricts extractive industry access
  • Travel management plan provision allowing mechanized use creates tension with conservation goals
  • Vague 'valid existing rights' reservation may generate disputes over scope of retained uses
  • Automatic reservation of future federal acquisitions within boundaries could extend restriction without further proclamation
