A native plant called Cuscuta australis was studied to see how it affects three invasive plants and the native plant community. The researchers found that C. australis can easily infect invasive plants like Ipomoea cairica, Mikania micrantha, and Wedelia trilobata, but not native plants. When growing on the invasive plants, C. australis grew well and reproduced more. The infection by C. australis reduced the growth and nutrient levels of the invasive plants, which in turn helped the native plants by increasing their species diversity and number. This shows that C. australis can help resist invasive plants while supporting the native plant community. The study suggests that using native plants like C. australis could be a natural and effective way to control invasive species and protect native plants.
