Invasive alien plants are among the most important groups of invasive species affecting both the socio-economic well-being of Pacific people and the islands’ unique ecosystems. Invasive species make ecosystems and communities more vulnerable to natural disasters and the impacts of climate change.
The 22 Pacific Island Countries and Territories include some of the smallest and most isolated countries in the world. Invasive plants contribute to reductions in biological diversity and can have significant economic impacts.
The only feasible method for controlling widespread invasive weeds involves using their own natural enemies against them. This approach has been safely and successfully used worldwide for more than a century.
In the Pacific example of weeds which have been successfully controlled through the use of natural enemies include broomweed (Sida spp.), giant sensitive plant (Mimosa diplotricha), grand balloon vine (Cardiospermum grandiflorum), lantana (Lantana camara), mile-a-minute (Mikania micrantha), water hyacinth (Pontaderia crassipes), water lettuce (Pistia stratiotes), and the African tulip tree (Spathodea campanulata)
