Abstract. Seseli olivieri (Apiaceae) is an exclusive species of the Alborz Mountains, Iran. In this research, the effect of environmental conditions on the vegetative traits and essential oil compounds of this species was investigated. For this purpose, three habitats with different heights were selected and the vegetative characteristics of this species were measured. In each habitat, soil samples and flowering branches of this species were collected and analyzed in the laboratory. The relationship between the functional traits of this species and environmental factors was determined using CA and PCA. Variance analysis of functional traits and soil parameters showed a significant difference between the three habitats. The highest values of vegetative traits were related to Tuyeh habitat. In Tange Kavard habitat, the main effective substances were Apiol and cis-Cadina-1(6),4-diene; in Enzo habitat, Apiol and Bornyl acetate; and in the Tuyeh habitat, Bornyl acetate and α-Pinene. Among the environmental factors, altitude, annual precipitation, annual temperature, minimum temperature of the coldest month, minimum absolute temperature, lime and nitrogen had the most significant correlation with the functional traits of this plant. Based on the IUCN criteria, the conservation status of this species was determined in the critically endangered.
