🌳 Ever wonder what tree rings really mean? They’re not just age markers—they’re living records of climate, fires, and human history.

Tree rings: Nature’s timeline of climate, fire, and human history.

From drought cycles to ancient civilizations, tree rings reveal the past like a natural timeline. 📚🌿

If you’ve ever looked at a tree stump, you’ve probably seen the concentric rings and guessed they tell a tree’s age. But tree rings do far more than count years. They are living archives, recording climate, forest health, fire history, and even human activity.

From the eastern forests of the United States to ancient archaeological sites, tree rings have helped scientists uncover stories about the past. This field of study—dendrochronology—uses ring patterns to date events and reconstruct environmental conditions, sometimes stretching back thousands of years.
