New Caledonia: one of the hotspots of global biodiversity


New Caleodnia has long been considered as an isolated Gondwanian island belonging to Australia due to its flora from the Jurassic period, but this notion is now highly contested by geological data. Its flora, nevertheless, contains numerous groups that are extremely ancient and can be considered a prime case study for plant evolution.


A bit of history :

New Caledonia: one of the hotspots of global biodiversity
Some 55 million years ago, tectonic forces raised the oceanic plate that overlaps New Caledonia’s Grande Terre, elevating its East coast. Thus the central mountainous chain was created, spanning the entire length of the main island. This ridge separates the two coasts of contrasting climates and geography: a West coast that is dry with vast plains and savannahs, and an East coast that is wetter with valleys boxed in by mountains descending directly into the ocean.

A biodiversity to be protected and studied

New Caledonia: one of the hotspots of global biodiversity
Environmental management falling within provincial jurisdictions, each province implements its own specific regulations for the protection of both ecosystems (land and marine reserves) as well as endangered species (regulations pertaining to hunting, fishing, fire and gathering animal and plant material).
