Kanak people
Kanak languages are extremely diverse, but French serves as the official language of New Caledonia. There are 28 distinct Kanak languages, as well as many dialects, out of the 1,200 Melanesian languages spoken throughout the Pacific. They are mutually incomprehensible. All are a part of the Oceanic branch of the Austronesian family. They all belong to the New Caledonian subgroup – except for Fagauvea, which is a Polynesian language.
Biodiversity of New Caledonia
Some New Caledonia plant communities are true living fossils. Flora contains many groups of plants that appear to be remnants of the Gondwanan flora in late Cretaceous - early Tertiary that once covered large parts of Australasia. The flora is exceedingly diverse and includes a level of endemism, per square kilometre, seen almost nowhere else on Earth. Three quarters of native plant species on New Caledonia are endemic, but a quarter of those are "at risk" of decline or extinction.
There are besides 454 species of marine macrophytes.
