The flora of Madagascar consists of more than 12,000 species of vascular and non-vascular plants. Around 83 per cent of Madagascar's vascular plants are found only on the island. These include five entirely endemic plant families as well as most of the over 900 orchid species, the traveller's tree, the Madagascar periwinkle, six species of baobab (pictured) and around 200 species of palms. The high degree of endemism is due to Madagascar's long isolation following its separation from the African and Indian landmasses in the Mesozoic Era. Today, humid forests, including the lowland forests, are found on the eastern plateau. Much of the central highlands is grassland. In the west are dry forest and succulent woodland. Unique spiny thickets are in the southwest, and mangroves occur on the west coast. While 10 per cent of the land surface is protected, much of the native flora is threatened, especially through dramatic deforestation.
