Leaf to Landscape Project

By Wendy Baxter

After the fourth consecutive year of severe drought in California, a team of scientists came together in the summer of 2015 to study the impacts of the historic drought on the world’s largest trees, the giant sequoias. Within Sequoia National Park lies the largest giant sequoia grove, Giant Forest. People from around the world travel to this majestic forest growing upon uplifted granite on the western side of the Sierra Nevada mountains. Few who make the pilgrimage to walk amongst these ancient trees leave unimpressed. Their longevity, resilience, size and beauty remind us of our impermanence, yet inspire us to ensure the continued reign of these Sierra giants for generations to come.

The National Park Service (NPS) assembled the team of scientists from the Carnegie Airborne Observatory, United States Geological Survey and the University of California at Berkeley to study the trees from their leaves all the way up to the entire landscape. Coordinated by the NPS and carried out by scientists with diverse approaches and perspectives, the scientists joined forces to become the Leaf to Landscape Project. Studying the trees at different scales will provide fundamental information about how individual giant sequoia trees respond to drought and will help managers identify specific areas of the forest where trees are more vulnerable to drought and climate change. Managers of these precious forests can then make difficult decisions about where to allocate their limited resources toward protecting vulnerable areas with management techniques such as prescribed fire.

About Save the Redwoods League


Since 1918, Save the Redwoods League has protected and restored redwood forests and connected people with their peace and beauty so these wonders of the natural world flourish.

Student Perspectives: Keep Cool and Save the Redwoods


We go through our lives doing similar things day after day. We wake up and check our phones, and then we go to school or work, and finally, finish our day running errands or relaxing. But there is one HUGE thing that most people don’t even see or realize is right in our backyard: There are redwood trees that we sometimes take for granted and might not really think about visiting.

Even the youngest scientists can help us track the health of the redwood forest with our Fern Watch project.

The most common plant in the redwood forest is probably a fern: the Western sword fern. And this prehistoric plant, which is found in every redwood forest, is telling us a story about how the forests are responding to changes in climate.
