Geography Question:

Bogs are most abundant in the Northern Hemisphere, especially in a broad belt including the northern part of the deciduous forest zone and the central and southern parts of the boreal forest zone. Farther south, and in drier climates farther inland, they become sporadic and restricted to specialized habitats. To the north, peat lands controlled by mineral soil water (aapa mires) replace them as the dominant wetlands.

Bogs are much less extensive in the Southern Hemisphere because there is little land in cold temperate latitudes. In these Southern Hemisphere peat lands, Sphagnum is much less important, and Epacridaceae and Restionaceae replace the Ericaceae and Cyperaceous of the Northern Hemisphere.
