The Hawaiian tropical rainforests are a tropical moist broadleaf forest ecoregion in the Hawaiian Islands. They cover an area of in the windward lowlands and montane regions of the islands.〔 Coastal mesic forests are found at elevations from sea level to . Mixed mesic forests occur at elevations of , while wet forests are found from . Moist bogs and shrublands exist on montane plateaus and depressions.〔 For the 28 million years of existence of the Hawaiian Islands, they have been isolated from the rest of the world by vast stretches of the Pacific Ocean, and this isolation has resulted in the evolution of an incredible diversity of endemic species, including fungi, mosses, snails, birds, and other wildlife. In the lush, moist forests high in the mountains, trees are draped with vines, orchids, ferns, and mosses. This ecoregion includes one of the world's wettest places, the slopes of Mount Waialeale, which average of rainfall per year. ==Coastal mesic forests== Coastal mesic forests are found on the windward slopes of the major islands from sea level to . These forests have been dominated by the native hala (''Pandanus tectorius'') and hau (''Hibiscus tiliaceus'') and naturalized (Polynesian introductions) kukui (''Aleurites moluccana'') and milo (''Thespesia populnea'') for the past 1,000–2,000 years. The Polynesian-introduced noni (''Morinda citrifolia''), pia (''Tacca leontopetaloides''), and kī (''Cordyline fruticosa'') are also common in this zone. Other native species include pololei (''Ophioglossum concinnum''),〔 ākia (''Wikstroemia'' spp.), loulu fan palms (''Pritchardia'' spp.), ōhia lehua (''Metrosideros polymorpha''), and lama (''Diospyros sandwicensis'').
