Ailanthus altissima: An invasive species in modern ecosystems
2025
Savić Aleksandra
Ailanthus altissima is an invasive woody species native to China and northern Vietnam, which has spread to all continents except Antarctica. Due to its rapid growth, intensive vegetative and generative reproduction, and resistance to unfavourable conditions, it poses a serious ecological and economic problem. The spread of this species threatens natural habitats by displacing native species and disrupting ecological balance, while in urban areas, it can cause infrastructural damage. Its control is complicated by its ability to regenerate through root suckers and the high production of seeds that can be dispersed over long distances by wind. Current control approaches mainly rely on chemical treatments by injecting herbicides into the trunk, but none of these methods are entirely effective. Mechanical removal is also used but often leads to even more vigorous growth. Research on biological control methods, including the use of specialized pathogens and herbivores, has yet to yield definitive results. Given the negative ecological and economic consequences, continuous monitoring of this species' populations and the implementation of integrated control measures are necessary. An effective control strategy requires a combination of chemical, mechanical, and biological methods, along with raising public awareness of the importance of timely action to limit its further spread.
