Citizen scientists out on a nature walk in San Francisco.

SAN FRANCISCO, CA (September 7, 2023)— Today the California Academy of Sciences and partners across the City are thrilled to announce the new Reimagining San Francisco urban nature alliance, which brings together a diverse and growing group of 32 organizations in collective action to improve the ecological health of San Francisco and equitably distribute the benefits of local nature to all.

The alliance is the result of a year-long effort spearheaded by the California Academy of Sciences to bring together local leaders from government agencies, nonprofits, and educational organizations to co-create a vision and strategy for a healthier and greener San Francisco. The creation of the alliance is a key element of the Academy’s Thriving California initiative, which harnesses scientific data and mobilizes diverse communities to fight climate change, stop biodiversity loss, and advocate for nature in the Golden State.

“It’s no easy feat to rally this many institutions behind a single cause, but every organization in this alliance knows that the change our city needs cannot be done by one organization alone,” said Rebecca Johnson, co-director of the Academy’s Thriving California initiative and a leader on the Reimaging San Francisco steering committee. “I hope that seeing just how many organizations are committed to working together toward a San Francisco where people and nature thrive together will spark optimism among San Franciscans for the future of our beautiful city. With the combined resources, brilliance, and passion of this many organizations and talented individuals, we can be a powerful agent for regenerating San Francisco.”

Reimagining San Francisco was announced today, California Biodiversity Day, at a press conference on the California Academy of Sciences’ Living Roof, with remarks from City leaders and Reimagining San Francisco partners.

During the press conference, the alliance outlined its bold and ambitious goals:

  1. By 2030, 30% of San Francisco is biodiverse greenspace.
  2. A comprehensive network of biodiverse corridors provides free movement for local wildlife and people.
  3. Natural lands management is fully resourced for management, conservation, restoration, and the ongoing addition of new lands.
  4. Everyone in San Francisco has easy access to nearby nature.
  5. San Francisco’s many neighborhoods have the resources, know-how, and city support to promote, create, restore, and steward biodiverse nature in their communities.
  6. Creating biodiverse landscapes in the built environment becomes routine.

“Our Reimagining San Francisco partner organizations are already engaged in impactful work to make our city a healthier place for both people and nature. But we are confident we can reach even higher if we work collaboratively,” said Academy Executive Director Scott Sampson, PhD. “Together we can realize a future where abundant nature is deeply interwoven with the built environment. Whether in backyards, schoolyards, courtyards, or street medians, nature-rich spaces brimming with life will replace expanses of asphalt and concrete and equitably distribute nature access across the City. The end result will be a thriving, diverse community for humans and nonhumans alike. San Francisco has the opportunity to reimagine itself and, in doing so, become a global leader helping to imagine thriving, regenerative cities for the 21st century.”

“For communities of color, Reimagining San Francisco translates to reconnecting the people to the land,” said Dr. Hollis Pierce-Jenkins, executive director of Literacy for Environmental Justice, a nonprofit that formed because Bayview residents organized to demand the creation of California's first urban park. “The great migration from the South to the West Coast was based on Black people imagining a future where they could own property and build wealth. Many fled the racial barriers in the South to explore a more progressive space in San Francisco.

“A new generation needs to embrace history, learn from elders, and reclaim their love affair with the outdoors in ways that are holistic and healing. The cultural footprint in green spaces needs to reflect the diverse contributions of the people. Justice outside brings gratitude, healing and re-alignment with nature,” she added.

Over the coming year, as the alliance continues to grow and welcome new members, it will identify an initial portfolio of projects with meaningful community impact that are only possible through the collaboration enabled by the alliance.

Following the press conference, the Academy’s celebration of California Biodiversity Day continues throughout September 7 with a 12-hour live-streamed event featuring 50 environmental experts naming California’s flora and fauna, and a California biodiversity-themed NightLife event (21+). Additionally, on September 9, the Academy will co-host a community science bioblitz in the Sacramento region alongside the California Natural Resources Agency and California Department of Fish and Wildlife.
