Association for Tree-Ring Research

The Association for Tree-Ring Research is an organization dedicated to studying tree rings to understand environmental and climate history. By examining the patterns and widths of tree rings, researchers can learn about past weather, droughts, and ecological changes over centuries or millennia. The association connects scientists, students, and professionals interested in dendrochronology— the science of dating and interpreting tree rings. It promotes research, education, and the sharing of findings to deepen our understanding of how natural and human activities impact the environment over time.
