Endemism, an organism being "endemic" means exclusively native to a place or biota. for example Santalum Album is endemic to Nusa Tenggara, Indonesia

Santalum album is a small tropical tree of the Santalaceae family, the most commonly known source of sandalwood. This species has been utilised, cultivated and traded for many years, some cultures placing great significance on its fragrant and medicinal qualities. For these reasons it has been extensively exploited, to the point where the wild population is vulnerable to extinction. It still commands high prices for its essential oil, but due to lack of sizable trees it is no longer used for fine woodworking as before. The plant is widely cultivated and long lived, although harvest is viable after 40 years.
