To evaluate the climatic impacts and future climatic changes on geographical distribution of the Dodartia orientalis, an invasive weed species in the world and Iran, a study was conducted in Ferdowsi University of Mashhad, using CLIMEX software, during 2016. The results represented that the plant species has a distribution potential in the world towards east china, most east European countries and central states of USA. So that the regions relies in the geographical position of 35 to 55 northern altitude which gradually will extend towards the higher northern altitude that leads to limited continental spread of the plant to Africa, Australia and south America. The distribution pattern of the weed in Iran was found mostly in North, Razavi, and South Khorasan, , Kohkiloyeh, Chaharmahal, Fars, Lorestan, Ilam, Kermanshah, Hamedan, Central and Tehran provinces which will be highly expanded towards the country North West provinces as a result of the occurrence of climatic changes. Therefore to manage this weed, while taking steps towards its quarantine; further studies on the control methods and tools to restrict its establishment, development and expansion should be conducted in vulnerable countries at risk.
