A forest that develops as a bog fills and dries. In boreal North America and Eurasia bog forests develop in post-glacial kettle holes that filled with water and were later colonized by bog plants, especially Sphagnum mosses. As the sites dry out further, trees become established, eventually producing forests typically dominated by Picea mariana (black spruce), Larix laricina (tamarack), and Pinus banksiana (jack pine), with associated herbs and shrubs. In tropical regions bog forests develop in coastal regions; those in Asia are often dominated by Shorea albida (alan). See also ombrogenous bog.
