One of three species in the mesite family, Mesitornithidae, it is classified as vulnerable by the International Union for Conservation of Nature (IUCN). It has a small population and is restricted to five sites in the north and west of the island, and one in the east.

Australia (continent) collision also pushed up the islands of Wallacea, which served as island 'stepping-stones' that allowed plants from Southeast Asia's rainforests to colonise New Guinea, and some plants from Australia–New Guinea to move into Southeast Asia. The ocean straits between the islands were narrow enough to allow plant dispersal, but served as an effective barrier to exchange of land mammals between Australia–New Guinea and Asia. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae ("Banksia"), Myrtaceae ("Eucalyptus" – gum trees),
