The Tree of Heaven (Ailanthus altissima), an invasive species originating from East Asia, has been identified as a significant threat to Polish and European Union ecosystems. The plant is known for its aggressive growth, ability to thrive in poor conditions, and its capacity to damage infrastructure such as roads, sidewalks, and building foundations through its root systems.

Authorities have implemented strict regulations, including a ban on the intentional cultivation, reproduction, and sale of the species. Violations can result in fines of up to one million PLN. Because the tree releases toxic chemicals that suppress native vegetation, ecologists and the General Directorate for Environmental Protection are urging its removal to protect local biodiversity. Under current Polish law, the tree can be cut without a standard permit, though experts note that the root system must be targeted to prevent regrowth.
