On Friday, October 6th, our Loma Prieta Chapter community joined in celebrating the 2023 Guardians of Nature honoree Florence LaRiviere while raising essential funds for our Chapter advocacy work. I want to take a moment to express my sincere gratitude for your invaluable support. 

For those who were able to attend, I trust that you left as inspired as I by Florence’s incredible achievements that gifted us with the largest urban wildlife refuge in the nation, and that you were moved by the warm sense of community that defines our Sierra Club Loma Prieta Chapter. 

To relive the memorable moments, please visit our Facebook photo album. Please enjoy this wonderful tribute video by David Simon and crew 

and one from Congresswoman Zoe Lofgren. 

I’m thrilled to report that more than 200 guests joined us, and that we have raised more than $80,000! This achievement speaks volumes about the generosity of our sponsors, donors, ticket purchasers, and winners of our online silent auction items. 

It is worth noting that our Guardians of Nature Benefit is our primary fundraising event, and the raised funds are integral in enabling us to support our staff and volunteers in advancing our work to “Explore, Enjoy and Protect our Planet”.

I eagerly await next year to welcome you to our 2024 Guardians of Nature Benefit. Thank you again for your unwavering support.

Your contributions save local lands and local lives.

Florence LaRiviere

Florence LaRiviere 

In 1951, La Riviere was a young mother living in Palo Alto with her husband, Philip, and their two young daughters. On warm days she and her husband would take their little girls to the cool shores of the marshland, where they would watch the birds as the breeze rippled the tall grasses on the edge of the water.  When they realized that the city was dredging mud from the Bay and dumping it on the pristine marsh, they realized they had to do something. Founding Citizens Committee to Complete the Refuge, the couple spent the next five decades in ceaseless advocacy for preserving the natural wetlands of the area, along the entire shore of San Francisco Bay. They recruited fellow activists, joined with other environmental groups, persuaded politicians to write legislation, blocked developers, and succeeded in helping to restore and preserve thousands of acres of natural wetlands, including Baylands Nature Preserve, San Francisco Bay National Wildlife Preserve, and Bair Island preserve. Due to the efforts of Florence and her many volunteers, the habitats of native and migratory birds are protected from encroachment by humans. Florence LaRiviere’s tireless efforts and leadership are an inspiration to all those who value the health and beauty of the natural environment which we all share, and who believe they can make a contribution to its preservation.
