Tree Rings: Nature’s Timekeepers and Windows to the Past Trees are more than just silent sentinels standing in forests and urban landscapes—they are living archives of environmental history. One of nature’s most remarkable records lies in the concentric tree rings that form beneath the bark of every tree. These carefully layered growth bands, visible when a tree is cut or examined closely, offer scientists, ecologists, and climate researchers a precise timeline of centuries past. This article explores what tree rings are, how they form, and why they are vital tools for understanding climate, ecology, and the long-term health of our planet. --- ### What Are Tree Rings?
