The distribution and habitat suitability of plant species are greatly influenced by climatic variables. Understanding these factors and their proportional contribution is valuable as it enables us to identify new habitats and farms for the cultivation and transfer of plant species, leading to increased production of important crops. Species distribution modeling (SDM,s) play a crucial role in predicting and comprehending the range of plant communities. Among these algorithms, the MaxEnt model has gained substantial popularity and is extensively utilized to assess the ecological needs, environmental responses, and habitat suitability of species [1]. Coriandrum sativum L., commonly known as Coriander, is a highly valuable medicinal plant extensively used in the production of medicines and food industries [2]. Understanding the key influencing factors in the spread of this species is essential for identifying suitable areas to establish new farms and expand its cultivation. So, the current study aimed to identify the effective climatic factors that significantly impact the distribution of coriander in Iran, utilizing the MaxEnt model. The study findings revealed that the distribution of coriander is influenced by several key factors, namely BIO12 (Annual Precipitation), BIO10 (Mean Temperature of Warmest Quarter), BIO7 (Temperature Annual Range), BIO2 (Mean Diurnal Range), BIO15 (Precipitation Seasonality), BIO6 (Min Temperature of Coldest Month), and BIO18 (Precipitation of Warmest Quarter Participation). The research indicated that coriander thrives in areas with annual precipitation ranging from 350-500 mm, a mean temperature of the warmest quarter between 17-27 °C, a temperature annual range exceeding 35 °C, a mean diurnal range greater than 14 °C, and a minimum temperature of the coldest month falling within the range of -12 to -2 °C. By considering these factors, suitable areas for coriander cultivation can be identified, helping establish new farms and expand the cultivation of this valuable medicinal plant in Iran.
