Seychelles is among the world's leading countries to protect lands for threatened species, allocating 42% of its territory for conservation. Like many fragile island ecosystems, Seychelles saw the loss of biodiversity when humans first settled in the area, including the disappearance of most of the giant tortoises from the granitic islands, the felling of coastal and mid-level forests, and the extinction of species such as the chestnut flanked white eye, the Seychelles parakeet, and the saltwater crocodile. However, extinctions were far fewer than on islands such as Mauritius or Hawaii, partly due to a shorter period of colonizer occupation. Seychelles today is known for success stories in protecting its flora and fauna. The rare Seychelles black parrot, the national bird of the country, is now protected.
