The Forest Inventory and Analysis (FIA) program conducted a systematic inventory of the forests of Kosrae, Chuuk, Pohnpei, and Yap in the Federated States of Micronesia (FSM) in 2005 and 2006. Seventy-three permanent field plots were installed in a variety of forest types. Our estimates for this inventory are derived from a sample based on 161,917 acres on the four main islands in the FSM.
- Forest covers about 89 percent of the FSM.
- About 3 percent of the landscape was classified as urban land.
- Gross tree stem volume was about 609 million cubic feet for all size classes.
- Aboveground dry biomass for tree stems 5 inches and greater was estimated to be about 9.2 million tons.
- Approximately 11 percent of trees sampled showed some sign of damage, particularly by other vegetation and human disturbance.
- FSM’s forests are characterized by a wide range of tree diameters with relatively high species diversity compared to other Pacific Islands.
- 96 tree species and 206 understory species were measured on FIA plots.
- The average number of tree species per one-sixth-acre plot was seven.
