The annotated list comprises 425 species belonging to 91 families, including 342 dicotyledonous species (80.47%) and 83 monocotyledonous species (19.52%). Among the families, Poaceae was dominant, comprising 42 species (9.88%), followed by Asteraceae with 37 species (8.70%). Fabaceae and Amaranthaceae each had 32 species (7.52%), with an additional 23 species (5.41%) for Amaranthaceae. Solanaceae also had 32 species (7.52%), followed by Brassicaceae with 15 species (3.52%), and Euphorbiaceae and Polygonaceae each with 13 species (3.05%). The remaining families had 12 species (2.82%) or fewer. The biological spectrum showed that therophytes were the most prevalent life form, with 228 species (53.64%), followed by hemicryptophytes with 44 species (10.35%), nanophanerophytes with 39 species (9.17%), and geophytes with 32 species (7.52%). The leaf size spectrum revealed that nanophylls accounted for 138 species (32.47%), followed by microphylls with 119 species (28.00%), while 10 species were aphyllous. Additionally, 286 species (67.29%) had a simple leaf lamina, and 24 species (5.64%) had a spiny leaf lamina. The habitats in the study area are severely affected by continuous landslides and soil erosion, primarily due to overflooding and other natural disasters. https://tbj.ui.ac.ir/article_28605_94c1cb4722d2726072d7368467b3f404.pdf
