Help Track Redwoods as Climate Changes

Join the League's new Redwood Watch project today to help redwoods survive in the future. Find a redwood tree in a park, in your own backyard, or in a botanical garden around the world. Use the free Redwood Watch iPhone application powered by iNaturalist or your own camera to take a photo of the tree and submit it online. Get the iPhone app by clicking on the App Store button on your iPhone, then click on the search button and type "Redwood Watch." Watch our online tutorial to learn how to use the Redwood Watch iPhone application.

Redwood Watch is our new citizen science project. Citizen science allows the public to participate in scientific research, enabling people of all ages to learn about the natural world while helping scientists accomplish their objectives.

We don't yet know how climate change will impact the redwood forest, but when we understand where redwoods grow well today, we will be better able to predict where the redwood forests of tomorrow will thrive. Join Save the Redwoods League in protecting these forests today.

Watch this Google Earth video, Finding the Redwood Forests of Tomorrow, to experience the wonder of the redwoods and learn how you can help scientists study this majestic forest.

Explore Jedediah Smith Redwoods Using Google Earth

Now you can experience the redwood forest, home to the world's tallest trees, virtually. Using Google Earth 6.0.2, free software available on the Web, you can walk among ancient redwoods and fly over towering treetops in Jedediah Smith Redwoods State Park. Save the Redwoods League and Google created a model of this ancient redwood forest that's ready for you to explore using the 3D Trees layer of Google Earth.

How to Start Exploring

  1. Make sure you have downloaded Google Earth version 6.0.2 or higher. Download Google Earth here.
  2. Turn on the 3D buildings layer on the left side panel.
  3. Search for "Jedediah Smith Redwoods State Park, Crescent City, CA 95531"
  4. Once you arrive at the park, mouse over the zoom slider on the right side of the screen. Press the plus sign until you see the 3D trees.
  5. Mouse over the circles in the upper right corner of the screen and the use these controls to walk among the trees.
  6. Take your exploration further by downloading and opening the Redwood Watch Tour in Google Earth.

Help scientists track redwoods with our Redwood Watch iPhone app

The sight of hikers staring at their iPhones instead of the forested beauty around them could have ruined the day for Lisa Micheli, Ph.D.

Instead, the Executive Director of Sonoma County's 3,120-acre Pepperwood Preserve was thrilled. The six hikers were actually citizen scientists using the League's Redwood Watch mobile application to document the preserve's redwoods. Redwood Watch, powered by, allows anyone with an iPhone or a camera to help track redwoods and associated species as climate changes.

Just find a redwood tree in a park, your backyard, or in a botanical garden anywhere in the world. Then use the free application or your camera to take a photo of the tree and submit it online. Your photo is plotted on a map, and our scientists will use all the submissions to recommend conservation strategies.

Last year, Micheli asked Emily Burns, Ph.D., the Save the Redwoods League Director of Science, for advice on how to monitor the iconic trees. Because Pepperwood Preserve is inland from the coast's fog belt, Micheli hypothesized that its 9.5 acres of redwoods would be more sensitive to climate stress. As the climate changes, inland areas may become drier, which may in turn impact the redwoods' ability to reproduce and grow.

"The app is great because it's a way to start mapping our redwoods, help us prepare for a more intensive kind of monitoring and engage our citizen scientists," Micheli said. "We're teaching people how to use the tool, but we're also building community."

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.
