The Northern New Guinea lowland rain and freshwater swamp forests is a tropical moist broadleaf forest ecoregion of northern New Guinea.
Setting
The Northern New Guinea lowland rain and freshwater swamp forests extend across the northern lowlands of the island of New Guinea, lying between the New Guinea Central Range to the south and the Pacific Ocean to the north. It extends from the eastern shore of Cenderawasih Bay in Indonesia's Papua Province east to Morobe Province of Papua New Guinea.
Several east-west mountain ranges, including the Van Rees Mountains, Torricelli Mountains, and Finisterre Mountains, rise from the lowlands; these ranges are home to distinct montane rain forest ecoregions.
The ecoregion is drained by several of New Guinea's large rivers, including the Mamberamo, Sepik, and Ramu, and Markham
