The introduction and spread of non-native invasive organisms have resulted in the degradation of native forests. The encroachment of these exotic animals, plants, insects, and pathogens can alter native plant composition and disrupt indigenous species regeneration that will ultimately reduce biodiversity. Invasive pests will cause economic and environmental harm to native forests. If not managed, the continuous spread and domination of invasive forest pests can result in the displacement of certain native species to the verge of being threatened, endangered or extinct.
