Study of the Subassociations Formed by Woody Species of the Rosaceae Family in the Forest-adjacent Shrublands of Zangezur National Park

The presented article provides information about the vegetation of woody species from the family Rosaceae Juss. distributed in the forest-edge shrublands of the Zangazur National Park, located within the flora of the Nakhchivan Autonomous Republic. The article also offers extensive data on the phytosociological characteristicsof the woody plants from the Rosaceaefamily found in the studied area, as well as on the formations, associations, and for the first time, the subassociations identified by us that are formed by these species. As a result of our numerous studies, for the first time, the vegetation of the forest-edge shrublands of Zangazur National Park has been classified based on dominant species. In this classification, dominant species are defined as those with a presence of 50% or more, subdominants around 10%, and other species are evaluated as accessory (assector) species. According to our research, for the first time, a phytosociological classification of the vegetation formed by the woody species of the Rosaceae family in the forest-edge shrublands of Zangazur National Park has been carried out. As a result, 2 formations, 6 associations, and 3 subassociations were identified, and the term subassociation has been applied by us as a unit within the vegetation classification.
