Valley Oaks: An Ecological Journey Through Time takes a journey from the canopy to the cosmos, exploring the history and ecology of one of California’s most iconic and threatened tree species, the Valley Oak. California Academy scientists, indigenous partners, and historical ecologists from the San Francisco Estuary Institute reveal how Valley Oaks and humans are intertwined in a relationship of disturbance and adaptation, with implications for the health and well-being of Bay Area communities.

 

This event originally took place at the California Academy of Sciences’ Morrison Planetarium (San Francisco, CA) on December 8, 2011. There were two screenings and dialogues that hosted over 520 people representing a diverse array of participants ranging from policy makers, local tribes, NGOs, educators, and scientists working to help re-establish the Valley Oak in Northern California as well as public audiences during the Academy’s NightLife after-hours event.

Plant Productivity in a Warming World

The past decade is the warmest on record since instrumental measurements began in the 1880s. Previous research suggested that in the ’80s and ’90s, warmer global temperatures and higher levels of precipitation — factors associated with climate change – were generally good for plant productivity. An updated analysis published this week in Science indicates that as temperatures have continued to rise, the benefits to plants are now overwhelmed by longer and more frequent droughts. High-resolution data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, indicate a net decrease in NPP from 2000-2009, as compared to the previous two decades

  • Re-Oaking the Valley: Bringing Native Trees Back into California’s Suburban Landscapes
    • “Re-Oaking” is an approach to reintegrating oaks and other native trees within the developed California landscape to provide a range of ecosystem services. The concept has emerged from SFEI’s research into the distribution and characteristics of California’s former valley oak savannas — a distinctive, widespread habitat that was mostly lost a century ago. Now valley oaks and other native trees are being recognized for the benefits they did — and could again – provide, as communities design the ecologically healthy and resilient landscapes of the future.

  • Green World Campaign 
    • We plant trees to restore the ecology and economy of some of the world’s poorest places. We help communities develop sustainable livelihoods, return barren soil to fertility, nurture biodiversity, and preserve cultural values.
  • American Forests
    • American Forests, the oldest national nonprofit conservation organization in the country, advocates for the protection and expansion of America’s forests. Since 1990, we have planted nearly 40 million trees. Our goal is to work with our partners to plant an additional 25-30 million trees in forest restoration projects during the next five years. We restore watersheds to help provide clean drinking water. We replant forests destroyed by human action and by natural disasters.
