Rather, the forest floor of rainforests is actually quite open because of the dense shade that occurs in rainforests. A major problem facing rainforests is continuous and heavy use by humans in need of agricultural land. Because the rainforest floor is not very rich in nutrients, most land is used only for a few seasons before the farmers move on. Hence, trees here are deciduous , which means they shed their leaves during the dry season. Forest is open canopied and sometimes grades into woodlands Open canopy allows light to reach lower levels in the forest, creating a denser secondary layer.
Trees are generally lower than the rainforest trees, but again have massive trunks.
Associated with the moist subtropical climate, Cfa, which we have in the Southeastern U.S., also in southeastern China, and southern Japan. Because of the favorable climate, most of this area is now cultivated with little natural vegetation . The subtropical broadleaf forest has relatively few species of trees which are not very tall. Species include palms, tree ferns, bamboos, shrubs, and herbaceous plants. Evergreen broadleaves include magnolias and laurels, and forests are sometimes called laurel forests .
