Therefore, it is necessary to study all parts of this genetic reserve and provide complete information to optimize forest management. Tuli-Nesa submountain forest, selected as the re-introduction and protection area of Maral, is located in the Talesh Mountain highlands. This floristic study identified 151 species of vascular plants belonging to 120 genera and 54 families and considered 15 species as rare and endemic. The largest families were Rosaceae and Poaceae and the most diverse genera included <em>Trifolium</em> and <em>Carex.</em> The chorological analysis showed that the most extended chorotype involved the Euro-Siberian elements (33%). In assessing the life form spectrum, the dominant life forms were Hemicryptophytes (48%). In this study, the vegetation types were determined by physiognomic-ecological and floristic methods. In this forest form, two types of tree layers and four types of herb layers were identified. Finally, the present study identifies the dominant species with the associate species and presents the plant types on the distribution map. https://tbj.ui.ac.ir/article_25648_1de138fe34270dc39973e736a4567383.pdf
