Introduction of invasive species into a new ecosystem may have various impacts such as including environmental harm,economic harm, or impact human health. After the establishment of population in a new area, a range of its habitat isexpanded. Hazard assessment for invasive species provides fundamental information for identifying current or future hazardouscondition, and it is important for the surveillance of pest occurrence as well as the development of control strategy. Itcan be also used for determining control areas and methods. Various approaches have been used in the hazard assessmentfor forest invasive species including statistical model, aerial approaches, and machine learning models. In this study, wepresent some approaches in the hazard assessment for forest pests including pine needle gall midge and pine wilt disease.
