Miconia calvescens (Melastomataceae)

[Miconia leaves are HUGE!]  An invasive weed in Hawaii

This page is dedicated to dissemination of information RE: Miconia calvescens (Melastomataceae), a species of tree from South America which, according to Dr. Ray Fosberg of the Smithsonian Institution, is "the one plant that could really destroy the Hawaiian forest." The invasive nature of Miconia in climates similar to that of Hawaii is evident from its invasion of Tahiti, where "[o]ver 60% of the island is heavily invaded with dark groves of Miconia trees, replacing the forest and its wildlife." For general information, see the text version of the WANTED: Locations of Miconia poster (full color image to be available soon). For more details on Miconia calvescens in Hawaii, see the Hawaiian Ecosystems at Risk (HEAR) project's Harmful Non-Indigenous Species (HNIS) report on Miconia calvescens PDF icon.

Additional information will be added to this page periodically. Hopefully, it can become a worldwide repository for information RE: Miconia calvescens as an invasive alien species.
