Kanak people
New Caledonia languages are divided into several groups. The Northern language group is tonal and includes 12 languages: Caac, Cemuhî, Fwâi, Jawe, Kumak, Nemi, Paicî, Pije, Pwaamei, Pwapwa, Yalayu, and Yuaga. Approximately 60,000 residents of New Caledonia speak at least one of the Kanak languages. Most of these languages are only in spoken form. There is no one unified language among the Kanaks; however, the largest group of Kanaks speak Drehu.
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.
