The invasive species *Ailanthus altissima* (Tree of Heaven) is a highly adaptable and aggressive plant native to China that has spread to disturbed areas worldwide. Its presence poses significant ecological threats by displacing native species, modifying habitats, and affecting ecosystem processes. The species reproduces both sexually through seeds and vegetatively through root regrowth, with seeds being the primary means of dispersal. Seeds are wind-dispersed and can germinate under various conditions, including shade and low light, with cold stratification being the most effective method for breaking dormancy. The species has a long seed longevity and can survive in a wide range of soils and climates, making it well-adapted to disturbed environments. Management strategies for *A. altissima* include mechanical, chemical, and biological control methods, each with its own advantages and limitations. Mechanical control is effective against seedlings but less so against established trees, while chemical control, particularly with systemic herbicides, is more effective. Biological control agents, such as mites and fungi, have shown promise but require further research to determine their efficacy and safety. The challenges in managing *A. altissima* include the need for long-term monitoring, the potential for soil/water contamination from herbicides, and the need to balance the allelopathic effects of the species with the conservation of native flora.The invasive species *Ailanthus altissima* (Tree of Heaven) is a highly adaptable and aggressive plant native to China that has spread to disturbed areas worldwide.
