what are coal forests
Etching depicting some of the most significant plants of the Carboniferous. Coal forests were the vast swathes of wetlands that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times.As vegetable matter from these forests decayed, enormous deposits of peat accumulated, which later changed into coal.Much of the carbon in the peat deposits produced by coal forests came from photosynthetic splitting of existing carbon dioxide, which released the accompanying split-off oxygen into the atmosphere.s vegetable matter from these forests decayed, enormous deposits of peat accumulated, which later changed into coal.
