Natural resources play a significant role in maintaining the environmental balance, biodiversity, and national economic development. Accordingly, planning to manage, organize, and optimally use these vital resources is necessary. During recent decades, affected by climatic challenges, decrease in rainfall, frequent droughts, and weakness in the country's planning system, natural resource areas, especially forests and pastures, have undergone significant changes including the destruction of forests and pastures. Accordingly, this study aims to examine the changes in the area of forests and pastures from 2006 to 2020 in the spatial areas of Iran. The study was applied in purpose and descriptive-analytical in the method. The data used were extracted from the Iranian Statistics Center. Data analysis was done using spatial statistics techniques in the Arc Map software environment. The findings of the research at the national level showed a significant decrease in the area of pastures and a relative increase in the area of forests during the investigated time. Among the provinces, 11 provinces had a decrease in the area of forests and 21 provinces had a decrease in the area of pastures. The findings of the spatial analysis also indicated the formation of three hot clusters related to the high levels of forest areas in the west and south of the country, as well as the formation of a hot cluster related to the high levels of pasture areas in the central and eastern regions of Iran.
