Redwoods and Climate Change Initiative
The results will help us make informed decisions about how to protect and restore redwood forests as they face rapid climate change.

Your support has enabled us to discover amazing things that will protect the redwood forest! The initial findings of the League's Redwoods and Climate Change Initiative (RCCI) program, released August 14, 2013, mark a huge leap forward in our understanding of redwood forests. The League's RCCI program brought together leading experts from the University of California, Berkeley; Humboldt State University; the Marine Conservation Institute; and several other organizations to study past, present and future impacts of climate change on coast redwood and giant sequoia forests.

Discoveries

  • Ancient redwood forests store at least three times more carbon above ground than any other forests on Earth.
  • The most comprehensive tree-ring record for coast redwood allows us see how different climate events, like droughts, fire and flooding, have affected redwoods' growth.
  • Changing environmental conditions have triggered a growth increase in coast redwoods and giant sequoias.
  • California summers have warmed, but precipitation has remained highly variable and not decreased over recent decades.
  • RCCI scientists discovered the oldest known coast redwood, at 2,520 years old!

The results will help us make informed decisions about how to protect and restore redwood forests as they face rapid climate change.

RCCI researcher Stephen Sillett called these first four years of the program "the golden age of redwood exploration."

Your generous support helped to make this research possible and funds are still needed to continue this critical work. The more we know about the redwoods, the better we can look after them. We look forward to learning and sharing much more through the important work of the RCCI program. Thank you.

Save the Redwoods League

For more than 90 years, Save the Redwoods League has been dedicated to protecting the ancient redwood forests so all generations can experience the inspiration and majesty of redwoods. In 1850, there were nearly 2 million acres of ancient coast redwood forests in California. Today, less than 5 percent remains and faces threats from unsustainable logging practices, poorly planned development and global climate change. Since its founding in 1918, the League has completed the purchase of more than 190,000 acres of land.
