"The natural vegetation in the Humid Subtropical climate zone is the subtropical evergreen forest. This forest occurs in two forms: broadleaf and needle-leaf. The subtropical broadleaf evergreen forest often has a well-developed lower layer of vegetation, including ferns, small palms, shrubs, and herbaceous plants. The subtropical needle-leaf evergreen forest of the southeastern United States is known as the southern pine forest. Loblolly and slash pines dominate the uplands. Bald cypress grows in the swamps of this area. Timber companies have created many plantations in the area yielding valuable lumber and pulp."
