Around the world, invasive plant species pose an increasing threat to native ecosystems and biodiversity. This study examines how invasive plant species affect native biodiversity, as well as the causes of their spread and management tactics used to stop them. The prevalence and spread of invasive plant species in various ecosystems may be impacted by the research site factors, such as elevation, climate, soil type, and past land use. It has been discovered that invasive plant species to take on native species for resources, change the structure and function of ecosystems, and decrease biodiversity. Cost-effective management methods have been found for many ecosystems after the efficacy and costs of various management techniques, including as mechanical removal, herbicide application, and grazing, were assessed. The development of more focused management techniques and knowledge of the processes behind how invasive plant species affect native ecosystems should be the main objectives of future study
