The document outlines three main types of forests: tropical rain forests which experience year-round high temperatures and rainfall and contain broadleaf evergreen trees; temperate deciduous forests like those in Ohio that have warm summers and cold winters with precipitation and are dominated by trees like oak and maple that lose their leaves seasonally; and evergreen coniferous forests found in places like Canada and the Rocky Mountains that have long cold winters and warm summers and are dominated by needle-leaf evergreen trees like spruce and pine that create acidic soil conditions.
