California’s coastal redwoods have stood for centuries, weathering a changing climate, logging, and time itself.
But in an era of hotter, more frequent wildfires, their future resilience depends on how we care for them, according to new research published in Forest Ecology and Management.
The study sought to understand the effects of wildfire on coast redwoods—the tallest trees in the world. Results revealed that redwoods in second-growth forests largely survived extreme wildfires in 2020 and quickly resprouted from their trunks and bases.
Researchers also discovered that forest structure—how dense the trees are and which species are present—strongly influences fire severity, highlighting the importance of management efforts such as thinning, reducing fuel loads, and encouraging fire-resistant species.
“Redwoods are remarkably resilient. But redwood forests are more than just redwoods, and the fires today are not the fires of the past,” says the study’s lead author, Jeff Kane, professor of Fire Ecology & Fuels Management at Cal Poly Humboldt.
