A Floristic Study of the Almabolaq Asadabad Protected Area in Hamadan Province

This survey studies the flora of the Almabolaq protected region, located west of Hamadan and north of Asadabad. The method for plant collection in this region followed the classical approach of plant taxonomic studies. Collected plants were identified, and their families, genera, and species were determined using essential references. An alphabetical list of taxa in this region was provided, based on families and scientific names. The collected plants were deposited in the Herbarium of the Agriculture and Natural Resources Research Center of Hamadan province. The biological spectrum of the region's plants was established by determining the percentage of species belonging to each biological form. Based on the data obtained from the geographical distribution of identified species and available references, the percentage of regional vegetative elements was determined. Using various sources, the endemic plants of Iran in the region and their conservation status were identified. The study found 50 families, 175 genera, and 275 species of plants in the Almabolaq region. The largest families are Lamiaceae (36 species), Fabaceae (28 species), Asteraceae (28 species), Brassicaceae (17 species), Caryophyllaceae (14 species), Poaceae (17 species), and Apiaceae (13 species). The life forms of plants include 49.09% Hemicryptophytes, 21.45% Therophytes, 15.27% Cryptophytes, 11.63% Chamaephytes, and 2.54% Phanerophytes. The Irano-Turanian element, comprising 58.9% of the flora, dominates the chorology of the region's plants. Thirty-one plant species are endemic to Iran.
