Many countries of the world suffer from the problem of invasive plants, which are harmful and poisonous, ravaging and controlling ecosystems, thus causing a massive loss of biodiversity and exacerbate environmental and climatic problems, and negatively affect health and the economy. There are many types of these plants, including the parthenium, which infiltrated Dhofar Governorate, and spread rapidly during the past ten years, despite governmental and civil efforts to extract the plant from its roots, the local plants did not grow again in the affected areas. This field study aims to know the impact of the parthenium on soil properties and how its spread contributes to environmental and climatic changes, and these properties include: surface temperature and at different soil depths, conductivity, salinity, acidity, and moisture. A time plan was set for the implementation of the study, by choosing the study site, which is Jebel Shihit, two adjacent sites were selected, one infested with Parthenium and the other not infested, and the measurements were repeated at each site three times, and then the results and data were collected and discussed within the team. After applying the protocols and comparing the results between the two sites, the team found that some properties of the soil in the infested area differ significantly from the non-infested area, the results showed a decrease in salinity, conductivity and humidity and an increase in soil acidity within the infested area, as well as the difference in the appearance of the soil and the extent of its cohesion between the two areas. The results showed that the soil change prevented the native plants from growing again, which led to an increase in the temperature in the infested site and thus contributing to climate change in the area.
