This collection of short videos highlight some of the research I've been part of while at UC Berkeley.
The videos below include footage of research conducted in the canopies of giant sequoias and coast redwoods that are located in State and National Parks. Climbing trees in these locations without a permit is not allowed. Recreational tree climbing is a legitimate activity, most of us grew up climbing trees, I know I did. Please climb responsibly and be respectful of the managers working to protect these majestic trees.
In the summer of 2015, the fourth consecutive year of severe drought in California, a group of scientists came together to study how the world's largest trees were faring in Sequoia National Park's Giant Forest. The scientists banded together to study the trees from the leaves all the way up to the entire landscape.
Giant sequoia drought
With California's historic drought heading into its fourth year, the need to understand the impacts on our iconic giant sequoias is in the forefront of the minds of managers and scientists.
Santa Cruz Drought Study
During the exceptional drought of 2014, a team of scientists conducted a study to investigate how the drought was impacting coast redwood, California bay laurel and Douglas fir trees in two locations. This video provides an overview of the study and the preliminary results.
While attempting to monitor the climate in coast redwood and giant sequoia forests across California, we ran into some rascally bears full of curiosity, determination and sheer brawn. They make it clear that scientists are no match for them and are merely visitors in the bears' domain.
Climate monitoring is an integral part of the Redwoods and Climate Change Initiative. Beginning in 2011, scientists from UC Berkeley installed weather stations across the range of coast redwood and giant sequoia forests. Monitoring environmental conditions over time at these study sites will enable scientists to understand how climate is changing in these iconic forests and may help identify sites that are changing more dramatically.
