Conifer bogs are dense to open, low to medium tall forests of needleleaf evergreen or deciduous trees with a peat substrate. Peatlands are usually distinguished by hydrological characteristics. The source and direction of flow of water determines the mineral nutrient status of a peatland. Conifer bogs occur from the Maritime Provinces of Canada through Quebec and Ontario south through New England and the Great Lakes States. Lake-filled conifer bogs are scattered extensively throughout Canada and the northern United States as far south as New Jersey and Ohio.
Conifer bogs are extensive across northern Minnesota.
