Sacramento River National Wildlife Refuge, National Wildlife Refuge in Butte County, United States.

The Sacramento River National Wildlife Refuge covers a large area alongside the river and includes riparian woodlands, grasslands, and marsh areas that support diverse wildlife. The habitat consists of different zones where birds, fish, and animals that live in this river system can find food and shelter throughout the year.

The refuge was created in 1989 and is still in an active acquisition phase, with the Llano Seco Unit among the lands it covers. Large-scale restoration of riparian forest is under way along the Sacramento River. Across the Sacramento Valley and foothills, riparian vegetation has fallen by about 85%, and by probably more than 95% along the region's major rivers.

The refuge's name comes from the Sacramento River, whose riparian forest has shrunk by about 85% across the Sacramento Valley and foothills. The Llano Seco Unit is part of the refuge, and large-scale riparian restoration is under way there. Visitors can watch this regrowth along the river corridor.

The refuge is in an active acquisition phase, so its units are scattered along the Sacramento River and access points vary by unit. The Llano Seco Unit is one of the included areas. Large-scale riparian restoration is ongoing, which can affect which trails and viewing spots are open. Check current conditions before visiting.

The refuge is managed as a mosaic of separate areas rather than one connected piece, which allows for more varied habitat care. This scattered approach lets managers optimize each section based on its specific needs.
