Other Threats
Over recent decades yellow crazy ants have emerged as one of the worst 100 invasive species in the world. Communities from Hawaii to Madagascar are trying to eradicate them, but no one has found a permanent solution yet. Christmas Island is a focal point for this international control effort. It is the only place where the ants are known to have formed supercolonies - groups with up to 300 queens that can contain millions of ants. These supercolonies spread further and cause more damage than single colonies, and they pose the single greatest known threat to the island's biodiversity. Staff from Christmas Island National Park have worked constantly in recent years to keep ant numbers in check. With help from the Christmas Island Crazy Ant Scientific Advisory Panel and support from the Australian Government they are holding ground.
