The monument was expanded on January 12, 2017

Expansion creates a Cascade-Siskiyou landscape that provides vital habitat connectivity, watershed protection, and landscape-scale resilience for the area’s critically important natural resources. 

By proclamation, President Barack Obama expanded the Cascade-Siskiyou National Monument in southwestern Oregon and the California Coastal National Monument to protect natural and cultural resources and areas of critical biodiversity, including highly important wildlife habitat.

Boundary enlargement of Cascade-Siskiyou National Monument

The 48,000-acre expansion of Cascade-Siskiyou National Monument, which includes a 5,000-acre extension into California, builds upon the original Monument’s goal to protect the area’s extraordinary biodiversity.

The monument and expansion area are an ecological wonder, home to an incredible variety of rare and endemic plant and animal species, and representing a rich mosaic of forests, grasslands, shrublands, and wet meadows at the convergence of three mountain ranges.

Expanding the Monument to include Horseshoe Ranch, the Jenny Creek watershed, the Grizzly Peak area, Lost Lake, the Rogue Valley foothills, the Southern Cascades area, and the area surrounding Surveyor Mountain creates a more contiguous landscape that provides vital habitat connectivity, watershed protection, and landscape-scale resilience for the area’s critically important natural resources.

The BLM fact sheet and Q&A describes, in brief, the expansion public process, expansion lands, and impacts on public access, grazing, and timber harvesting.

"We're proud to be charged with stewarding these incredible lands for future generations, including today’s additions to the Cascade-Siskiyou National Monument and the California Coastal National Monument,” said Bureau of Land Management Director Neil Kornze. “The BLM looks forward to continuing and expanding our work with local communities to ensure successful management of these special places"

US Department of Interior Secretary Jewel applauds new monuments and expansion.
