The main aim of this research was an integrated assessment of the ecological condition of natural forest complexes for the management of sustainable development in Khizi district, located on the territory of the Republic of Azerbaijan. Two test sites with different levels of anthropogenic impact were selected in Khizi. One of those sites is in the protected area of Altiaghac State Nature Reserve. The other test site is in the roadside area of Qizilqazma. The ecological condition of forest ecosystems on these test sites was investigated by a comparative analysis of the disruption degree of individual developmental stability at the ontogenesis of Quercus macranthera Fisch. et C.A.Mey. species' individuals. It is one of the dominant tree species in the forests of the study area. The degree of developmental stability of individuals was estimated by the level of fluctuating asymmetry of leaves morphological traits. The identification of the mineralogical composition of soil samples taken from test sites was carried out by XRD. The accumulative properties of oak were investigated by elemental analysis of leaf and soil samples. According to the results of research, fluctuating asymmetry of Q. macranthera leaves can be used as an effective indicator of the ecological condition of forest ecosystems in the Khizi district. But the results of the elemental analysis show that it is inexpedient to use the accumulation of elements in the Q. macranthera leaves as an indicator in environmental quality monitoring.
