Abstract
Invasive alien plant species (IAPS) pose a considerable threat to global biodiversity, ecosystems, and human health. The acceleration of globalization, heightened trade activities, and increased human movement have intensified the spread of these invasive species, rendering it a pressing concern that necessitates immediate action and thorough management approaches. Numerous nations are facing intricate and financially burdensome challenges related to invasive species. These species, which are non-native to their introduced environments, can inflict damage on ecosystems, economies, and public health. They frequently outcompete native species, disrupt ecological processes, and contribute to significant ecological disturbances. However, efforts to manage IAPS have often been undermined by the uncertainty among managers regarding the potential beneficial uses of these species. The Palakkad Gap, which is the focus of this study, is recognized as a biodiversity hotspot and is situated within the Western Ghats. It serves as a trade route connecting the states of Kerala and Tamil Nadu. The area has been invaded by IAPS, necessitating the implementation of management strategies to curb their spread and ultimately facilitate their removal from these ecosystems. Consequently, this study has undertaken the documentation of IAPS within the specified area.
