The nation has abundant forestry resources, particularly on the high islands, consisting of approximately 15,000 ha (37,000 acres) of forests. Two privately owned commercial sawmills are operated on Pohnpei; one in Kitti logging mangrove cedar, and one in Kolonia utilizing upland timber. Exploitation of the nation's forestry resources is limited, and virtually all lumber used in construction is imported ($2.1 million in 2000). Mangrove timber is used for handicrafts and furniture making.
