Earleaf Acacia: An Invasive Threat to Florida

Acacia auriculiformis, or earleaf acacia, is a fast-growing invasive tree threatening Florida’s native ecosystems, particularly low-elevation wetlands like the Everglades. Originally introduced as an ornamental, earleaf acacia now displaces native flora, alters nitrogen cycles, and reduces biodiversity. Current mechanical and chemical control methods are costly and limited in scale. Ecological niche modeling shows this species' potential to spread throughout the southeastern United States and other regions. Ongoing research into biological control agents like Trichilogaster sp. offers hope for long-term management. Public engagement, early detection, and education are essential for limiting this invasive species and protecting Florida’s ecosystems.
