New Guinea is the world’s largest tropical island, and can now boast the most diverse island plant life too, according to new research. An international team of researchers, including experts from New Zealand and Australia, has produced the first verified checklist of the vascular plants on mainland New Guinea and surrounding islands, documenting over 13,600 species. They argue that expert knowledge is essential for building checklists in the digital era, as online databases overestimate the species counts by 22 per cent.
