This research investigated the historical, ecological, and climatic characteristics of the Brant's oak (<em>Quercus brantii</em><strong> </strong>Lindl.)<strong> </strong>in Chaharmahal and Bakhtiari provinces. A typical single-stem <em>Q. brantii</em><strong> </strong>was selected and cut. Then, a disk sample was prepared. Dry weight and carbon content were measured using the combustion method. The number and width of the disc's annual rings were measured. In climate studies, temperature and precipitation anomalies were used. In addition to extracting all the morphological characteristics, this research showed that the amount of carbon stored in different organs increases with the woody tissue of the plant, and the amount of moisture in the plant organ decreases. The measurement of annual rings showed that the average growth diameter of the studied oak tree is 3.9 mm. The relationship between temperature anomaly and tree diameter growth data showed that the temperature variable has comprehensive control over the geographical distribution of the oak, and the <em>Q. brantii</em><strong> </strong>has a more robust response to temperature instead of precipitation variables.
