In 2008, the Forest Inventory and Analysis (FIA) program installed 44 permanent field plots in a variety of forest types in the Republic of the Marshall Islands (RMI), including Ailinglaplap, Arno, Jaluit, Kwajalein, Likiep, Majuro, Maloelap, Mili, Rongelap, and Wotje.
- Forest, including agroforest and coconut plantations, covers about 70 percent of the RMI.
- About 12 percent of the landscape is urbanized.
- Aboveground dry biomass for tree stems 5 inches and greater was estimated to be about 854,000 tons.
- About 37 percent of the trees sampled in the inventory had some form of damage, especially by insects and other vegetation.
- The RMI’s forests are characterized by a unique bimodal distribution of tree diameters owing to the dominance of coconut plantation combined with regeneration of other species.
- Species diversity is somewhat low compared to other Pacific Island groups.
- A total of 17 tree species and 45 understory species were measured on the FIA plots.
