About
The Kern River Preserve protects California's largest remaining lowland riparian forest. This vital Audubon-managed nature reserve, nestled in the Southern Sierra Nevada, is a designated Globally Important Bird Area, renowned for its extraordinary biodiversity and critical habitat for numerous species. It offers a serene escape into one of the state's most ecologically significant riverine ecosystems, making it a paradise for birdwatchers and nature enthusiasts alike.
Stretching across approximately 3,000 acres along the South Fork Kern River, the preserve is characterized by its lush cottonwood-willow riparian forest, providing essential nesting and foraging grounds. Key avian residents include the federally endangered Southwestern Willow Flycatcher, the federally threatened Western Yellow-billed Cuckoo, and the vibrant Summer Tanager. Beyond its remarkable birdlife, visitors might also spot diverse mammals such as Mule Deer and Bobcat, various reptiles like the Pacific Pond Turtle, and a rich array of native plants, including the rare Alkali Mariposa Lily.
Visiting the Kern River Preserve offers an immersive experience into a thriving natural landscape, where the sounds and sights of wildlife create unforgettable moments. While the main visitor center may have temporary access changes, the surrounding river forest remains accessible, offering unique opportunities for photography, nature education, and quiet contemplation. Its commitment to conservation and the sheer abundance of life it supports make it a truly special destination for anyone seeking to connect with California's natural heritage.

The Kern River Preserve's history dates back to the 1860s as part of Andrew Brown's cattle ranch. Recognizing its immense ecological value, particularly its pristine riparian forest, The Nature Conservancy acquired approximately 1,600 acres of the ranch in 1979 to protect it from development. In 1998, the National Audubon Society assumed ownership and stewardship of the preserve, continuing and expanding conservation efforts. Through subsequent acquisitions and partnerships, the preserve has grown to over 3,000 acres, ensuring the long-term protection of this critical habitat along the South Fork Kern River.
