Redwoods and Climate Change Scientists from Cal Poly Humboldt conducted a rangewide analysis of coast redwood (Sequoia sempervirens) to examine growth trends and understand how these trees are responding to recent environmental changes. They found that redwoods have varying sensitivity to drought, and that rising temperatures may affect tree performance in unexpected ways—results that are both concerning and hopeful. Coastal fog helps alleviate drought stress. Nighttime fog, in particular, is one of the best predictors of redwood growth efficiency.

Fisher Chair in Redwood Forest Ecology. Sillett’s team w...
