Once largely intact, the 1,600 East Melanesian Islands are now a hotspot, due, sadly, to accelerating levels of habitat loss, which has been caused chiefly by excessive logging, mining, and unsustainable farming practices. The region is one of the most geographically complex areas on Earth. Isolation and adaptive radiation have led to very high levels of endemism, both within the whole hotspot and on single islands. Notable endemic species include the majestic Solomons sea-eagle and more than a dozen threatened species of flying fox. The islands also harbor a diverse group of vascular plants species, including 3,000 endemics.
