Welcome!
The American River Natural History Association (ARNHA) proudly operates the Effie Yeaw Nature Center, the interpretive heart of the Lower American River Parkway. For more than 50 years, the Effie Yeaw Nature Center has welcomed our community to explore, learn, and connect with the natural world right here in Sacramento.
​
​​​As a 501(c)(3) nonprofit, we rely on the generosity of our supporters to keep this mission thriving. Memberships, programming, special events, and private donations all help fund the experiences that make the Center so special. Every contribution allows us to open our doors and share the wonders of nature with visitors of all ages.Through engaging educational programs, hands-on interpretive experiences, and rich learning resources, we inspire curiosity, connection, and stewardship of the environment.

Land Acknowledgement
In deepest respect, the American River Natural History Association (ARNHA) recognizes that the Effie Yeaw Nature Center (EYNC) sits on the unceded land of the Valley Nisenan peoples. The American River Natural History Association, EYNC, and the Sacramento Regional Parks, as co-stewards, will continuously work to uplift and affirm the voices of the local tribal nations through a mutual partnership that will aid in preserving and interpreting their thriving indigenous culture; not just depicting past history. ARNHA also commits to collaborating with local tribal nations to preserve the land in a manner that respects the beliefs and cultures of the first peoples of this area, who are vested and valued members of the Sacramento Community.
