The rings that form on tree trunks each year not only indicate the tree’s age but also serve as a natural archive that reveals the droughts, fires, and effects of climate change that occurred in the region years ago. 

Prof. Dr. Ender Makineci, a faculty member in the Department of Soil Science and Ecology at Istanbul University-Cerrahpaşa Faculty of Forestry, demonstrated the annual ring counting method they conduct at Yıldız Technical University’s Davutpaşa Campus by performing the procedure on a tree.

Makineci explained that the annual rings formed on tree trunks provide scientists with important retrospective environmental data, noting that the ages of trees—which can live for thousands of years—are determined by counting the annual rings taken from cross-sections of the trunk.
