Down to only 5% of its original forest landscape, New Caledonia in the southeast Pacific ocean is famous for its endemic species, meaning found no-where else in the world. According to a 2009 study, the island of New Caledonia supports some of the world's highest levels of endemic species, including five families of plants found no-where else on Earth.
The kagu (Rhynochetos jubatus), the only surviving member of the bird family Rhynochetidae, is probably the most well known of New Caledonia's endemic birds. In addition, the New Caledonian crows (Corvus moneduloides) have become highly publicized due to their incredible use of tools. The islands are also home to one of the world's largest geckos, the New Caledonian Giant Gecko (Rhacodactylus leachianus).
Yet, New Caledonia and the East Melanesian islands' forests are almost gone. Nickel mining and deforestation have level much of the islands' forests, while invasive species pose an additional threat to many of the areas endemics. A number of new Caledonian species have not been seen for a century.

Protecting global biodiversity must include islands
(05/12/2009) If the world is to save biodiversity, islands are key, according to a new study in the Proceedings of the National Academy of Sciences. The study found that while islands have fewer overall species than continental areas of the same size, they have far more endemic species, i.e. animals and plants that can be found no-where else in the world.
From Cambodia to California: the world's top 10 most threatened forests
(02/02/2011) Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.
