Habitat Notes Coprosma is a genus of about 90 species that are found in New Zealand (45 species) Hawaii (20 spp) and in Borneo, java, New Guinea, islands of the Pacific Ocean to Australia. These species are sensitive to climate change and drought, while also being habitat for endangered bird species have a direct link to each other. The genus Coprosma represents Hawaii's only wind pollinated dicots. Although extinct from Rapa Nui, Gossen noted it in the fossil pollen record of KAO3 in Rano Kao, but Skottsberg did not identify the plant alive by 1920. (Gossen, 2010)
