About Effie Yeaw
Lived 1900 – 1970 (aged 69).
Effie Yeaw (pronounced Yaw) (May 5, 1900 – January 3, 1970) was an educator, conservationist, and leader in efforts to protect the American River Parkway in Sacramento County, California.
Yeaw is best remembered for leading tens of thousands of schoolchildren on field trips along the American River in Deterding Woods (now Ancil Hoffman Park), inspiring public appreciation that contributed to the establishment and conservation of the American River Parkway. The Effie Yeaw Nature Center, built in Ancil Hoffman Park in 1976, was posthumously named in her honor.
Early life, education, and teaching career
Effie May Cummings Yeaw was born in Chico, California, on May 5, 1900. Her parents, Galen Cummings and Ella Stineman, were both teachers. Her family moved several times during her childhood, seeking favorable climate for her father, who had tuberculosis. Galen eventually died of the disease when Effie was five. Later in life, Yeaw recalled her father introducing her to desert wildflowers during walks in the Mojave Desert when the family lived near Barstow, California.
After her father died, Yeaw moved with her mother to Lincoln, California, and then to Sacramento. and throughout her life participated in committee work, led nature hikes, and assisted with the organization's annual bird census. In the 1950s, Yeaw founded and led the Carmichael Junior Audubon Society, which operated as its own club and reported its own bird census. Yeaw held conservation leadership roles in the Sacramento Audubon Society and the Sacramento River Valley District of the California Garden Clubs. left
In the late 1950s, Yeaw and other conservationists loosely organized as a "Committee of Concern," advocating for the creation of the American River Parkway. On February 28, 1961, they formed the Save the American River Association (SARA) to coordinate public campaigning for preservation of the parkway. SARA's efforts are recognized as a contributing factor leading to the Sacramento County Board of Supervisors' adoption of the American River Parkway concept in the county's 1962 General Plan and its implementation of the plan throughout the 1960s. SARA was credited for its public outreach educating county residents about the proposed parkway, including organizing speaker series, creating and distributing pamphlets, and producing a short documentary, Operation STAR, which aired on local television. Yeaw's youth field trips to Deterding Woods were prominently featured in these materials. The Sacramento Bee ran feature articles with large photo spreads of Yeaw's work in 1962 and again in 1963
Publications
In 1963, Yeaw wrote and illustrated a field guide, The Outdoor World of the Sacramento Region, published through the Sacramento County Office of Education. The guide was made available for free to Sacramento County teachers, sold thousands of copies, and continues to be published through updated editions.
Honors and legacy
Yeaw died of cancer in 1970, but the County Parks Department continued to employ nature tour guides in Ancil Hoffman Park to carry on Yeaw's work. The Effie Yeaw Nature Center was built in Ancil Hoffman Park in 1976 and named in her honor.
Yeaw’s conservation work was featured in numerous newspaper and magazine articles. In 1965, she received the American Motors Corporation Conservation Award. In 2009, the California Park and Recreation Society inducted Yeaw into its Hall of Honor.
