Changes in carbon storage of Quercus brantii Lindl in relation to physiographic factors ‎of Zagros forests

The aim of this study was to investigate the changes in the amount of dead wood carbon storage of Quercus brantii Lindl in relation to physiographic factors in Qalajeh forest of Kermanshah province. For this purpose, an area of ​​Qalajeh forest with an altitude range of 1400-2100 meters above sea level was selected, and the area was divided into seven elevation classes with a difference of 100 meters. Then, at the level of each elevation class, one-hectare sample plots with three replications were implemented to estimate the amount of standing and fallen dead wood carbon storage. In each sample plot, while specifying the slope and direction, in addition to quantitative measurements in line with the research goal in relation to standing dead wood, the sample line in parallel and at a suitable distance from each other to check and measure the fallen dead wood whose diameter was greater than or equal to 2 cm for Necessary measurements were implemented. The results of Pearson correlation test showed that there is a significant negative correlation between the amount of standing and fallen dead wood carbon storage with the altitude factor. Also, the results of analysis of variance showed that the changes in dead wood carbon storage of Quercus brantii Lindl in different physiographic units did not have a significant difference, which shows that the changes in dead wood carbon storage of Quercus brantii Lindl trees in the study area are independent of the Physiographic factors effects.
