What looks like a simple pattern of rings is actually a living archive recording fire, drought, insect outbreaks, saltwater intrusion, and shifting climate year by year. Through dendrochronology, scientists can read centuries of ecological change written in wood.

Tree rings form a natural archive, recording fire, drought, insects, saltwater intrusion, and climate year by year. Across the U.S., dendrochronology reveals the secrets trees hold. My latest project in Nature Conservancy Magazine
