Myrsine knudsenii Myrsine knudsenii Myrsine knudsenii, the Kokee colicwood, is a species of tree in the primrose family. It is endemic to the island of Kauai in Hawaii. It is threatened by habitat loss. This is a shrub or tree growing up to 4.5 meters tall with flowers occurring in clusters along the branches. It grows in moist forests dominated by "Acacia koa", "Metrosideros polymorpha", and "Dicranopteris linearis". It probably once occurred in several other types of ecosystem. There are three populations left, for a total of about 30 trees. It was federally listed as an endangered species of the United States
Greater koa finch regeneration of koa forests, while introduced black rats ("Rattus rattus") preyed on young birds. Avian pox ("Poxvirus avium") and malaria ("Plasmodium relictum"), spread by mosquitoes, may have also been a factor. However, even before these issues became important, the koa finches were probably already living in marginal habitat due to the loss of lowland koa forests, as evidenced by the extinction of the other koa finch species (which lived on lower-elevation islands) prior to European contact. Greater koa finch The greater koa finch ("Rhodacanthis palmeri") was a species of finch in the Fringillidae family. It was found only in the
