Mangrove trees are a type of above ground tree. They are notable for the fact that they are unique to a single biome: the mangrove swamp, a particular type of tropical saltwater swamp in which mangrove trees will grow near rivers and pools of water. Like the overwhelming majority of overland trees, mangrove wood is brown and produces brown products.
