Hardwood Forests

Mixed Mesophytic Hardwood Forests are found mainly on the loess bluffs and on slopes and ravines of areas highly dissected by streams and erosion. The soils are typically fertile and evenly moist. The vegetation is characterized by: Fagus grandifolia (beech), Platanus occidentalis (sycamore), Magnolia grandiflora (bull or southern magnolia), M. acumuinata (cucumber tree), M. macrophylla (big-leaf magnolia), M. pyramidata (pyramid magnolia), Liriodendron tulipfera (tulip poplar), Quercus alba (white oak), Fraxinus americana (white ash), Carya tomentosa (mockernut hickory). The understory may include: Cornus florida (flowering dogwood), Cercis canadensis (redbud), Ilex opaca (American holly), Ostrya virginiana (eastern hophornbeam).

Oak-Hickory Forests are found in dry to moderately moist uplands. The most abundant tree species include Carya tomentosa (mockernut hickory), Quercus stellata (post oak), Q. alba (white oak), Q. falcata (southern red oak), and Q. velutina (black oak).

Hardwood Slope Forests are mixed hardwood communities that may also include occasional pines. These communities are found along ridges and slopes above bottomlands intersecting pinelands. These areas are not as diverse as mixed mesophytic forests. Dominant trees include beech, southern magnolia, water oak (Quercus nigra), cherrybark oak (Q. falcata var. pagodifolia), tulip poplar, and sweetgum (Liquidambar styraciflua). Typical pines might include spruce pine (Pinus glabra), loblolly pine (P. taeda), and slash pine (P. elliotii).

Evergreen Maritime Forests occur just inland from the Gulf of Mexico. These communities are dominated by various species of pine (slash, loblolly and longleaf), beech, bull magnolia (Magnolia grandiflora), bay magnolia (M. virginiana), red bay (Persea borbonea), camphor tree, live oak (Quercus virginiana). Palm species include Sabal minor (dwarf palmetto), S. palmetto (cabbage palm), Raphidophyllum histrix (needle palm ), and saw palmetto (Serenoa repens).

Coastal Ridge Hammocks & Midden Hammocks are uncommon (the ridge communities are called cheniers in Louisiana). These island-like forests occur on elevated areas slightly above mean sea level, mostly along the western Gulf coast. Quercus virginiana (live oak) and Celtis leavigata (sugarberry) predominate.
Shell middens were inadvertently built by prehistoric First Nation people, as they processed and consumed clams and oysters and deposited the shells in Gulf shallows. Live oak, sugarberry, eastern red cedar (Juniperus virginiana), tallow tree (Triadicum sebiferum) and toothache tree are common components of these low lying islands in brackish and salt marshes.
