From a 1937 garden planting to an ecological crisis: One Miconia tree now spreads 8.9 million seeds, endangering Queensland's iconic rainforests

Today, a single mature Miconia tree can produce over 8.9 million seeds in one season. What began as a 1937 garden introduction in tahiti has turned into a high-priority biosecurity threat for Queensland’s World Heritage rainforests. This invasive weed smothers native understoreys, destabilizes soil, and threatens rare native species.
