The lansan tree produces a culturally and economically important resin, used by churches as a source on incense throughout the East Caribbean. However, traditional harvesting methods are extremely damaging to the tree. The Global Trees Campaign is supporting an initiative on Saint Lucia to improve the sustainable use of this species.
The lansan tree (Protium attenuatum) has all but disappeared from much of its range in Windward Islands (Eastern Caribbean). However recent surveys in Saint Lucia indicate that this small country currently holds the largest remaining population.
