NVCS association: Fagus grandifolia - Magnolia grandiflora - Pinus glabra - (Magnolia macrophylla) / (Illicium floridanum) / Hexastylis arifolia Forest
Database Code: CEGL007460
Formation: Mixed broad-leaved evergreen - cold-deciduous forest
Alliance: FAGUS GRANDIFOLIA - MAGNOLIA GRANDIFLORA FOREST ALLIANCE (I.C.2.N.a.2)
Element Concept
Summary: This forest occurs in ravines and on broad upland flats, on somewhat acidic to circumneutral loamy soils which are not subject to flooding, or sometimes in temporarily flooded situations. These mesic to dry-mesic forests occur in hilly transitional areas from longleaf pine hills to stream bottoms, and are often best expressed in areas of steep slopes (or along alluvial flats). Canopies are diverse; some common trees are Fagus grandifolia, Magnolia grandiflora, Quercus alba, Quercus pagoda, Quercus nigra, Quercus hemisphaerica, Pinus taeda, Pinus glabra, Liquidambar styraciflua, Nyssa sylvatica, Liriodendron tulipifera, Fraxinus americana, Quercus michauxii, Quercus falcata, Quercus velutina, Quercus laurifolia, Carya alba (in the north), Carya glabra, Ulmus alata, and Pinus echinata. Species in the subcanopy include Acer barbatum, Acer rubrum, Oxydendrum arboreum, Carpinus caroliniana ssp. caroliniana, Ostrya virginiana, Prunus caroliniana, Prunus serotina, Symplocos tinctoria, Magnolia macrophylla (rare to the west), Halesia diptera, Styrax grandifolius, Sassafras albidum, Ilex opaca, Hamamelis virginiana, Crataegus marshallii, Morus rubra, and Cornus florida. Common shrubs are Illicium floridanum (in some examples), Ilex longipes (in the west), Ilex vomitoria, Callicarpa americana, Euonymus americana, Hypericum hypericoides, Asimina parviflora, Osmanthus americanus (rare to the west), Viburnum dentatum, Amelanchier canadensis, Vaccinium arboreum, Chionanthus virginicus (rare to the west), Vaccinium elliottii, Aesculus pavia var. pavia, Sebastiania fruticosa, Persea borbonia, and rarely Stewartia malacodendron. Common woody vines include Vitis rotundifolia, Smilax rotundifolia, Smilax pumila, Smilax glauca, Smilax smallii, Berchemia scandens, Bignonia capreolata, and Lonicera sempervirens. The herb layer includes a mix of Hexastylis arifolia var. arifolia, Solidago arguta var. boottii, Pteridium aquilinum var. pseudocaudatum, Viola walteri, Arisaema triphyllum, Chasmanthium sessiliflorum, Chasmanthium laxum, Carex spp., Oplismenus hirtellus ssp. setarius (= Oplismenus setarius), Epifagus virginiana, Podophyllum peltatum, Uvularia perfoliata, Polygonatum biflorum, Mitchella repens, Trillium foetidissimum, Tipularia discolor, Polystichum acrostichoides, Dioscorea quaternata, Scleria sp., Aristolochia serpentaria, Sanicula canadensis, Lilium michauxii, Spigelia marilandica, Euphorbia corollata, Solidago caesia, Smilax herbacea (very uncommon), and rarely Chamaelirium luteum. The troublesome exotics Ligustrum sinense, Lygodium japonicum, and Lonicera japonica are usually present to a greater or lesser degree in stands of this type. This association occurs in the central and eastern Florida parishes (essentially east of the Amite River) of eastern Louisiana, and extends eastwards into the Coastal Plain of Mississippi, Alabama, and western Florida.

Synonymy:
IA8e. Beech - Magnolia Forest (Allard 1990) B. in part
Comments: Toward the northern edge of the range of this association, the canopy may contain substantial Quercus alba, Liquidambar styraciflua, and Fagus grandifolia; Magnolia grandiflora may be primarily in the subcanopy in these examples. See also Fagus grandifolia - Quercus alba - Liquidambar styraciflua / Magnolia grandiflora / Smilax pumila - Hexastylis arifolia Forest (CEGL007210) for a related slightly less mesic forest with less dominance by Magnolia grandiflora. The former Pinus glabra - Pinus taeda - Fagus grandifolia - Quercus alba - Magnolia grandiflora Forest (CEGL007510) has been merged into this association by making Illicium floridanum optional as a dominant shrub in the title and broadening the floristic description to include species in CEGL007510. Research into differences between the Louisiana and Alabama beech-magnolia forests and those in Panhandle Florida, if there are any, is warranted.
Conservation Ranking & Rare Species
GRank: G3 (99-12-05): Though widespread throughout the Southeast Gulf Coastal Plain, this community is not abundant anywhere. A relict of the Pleistocene glacial period, this community is restricted to relatively small areas of suitable cool, moist environmental conditions provided by ravine and stream slopes and upper river terraces (Delcourt and Delcourt 1977). Where it occurs on flat ground, this community is susceptible to urban/residential development and logging. On slopes, foot traffic, logging and feral hog activity are threats to the diverse herbaceous understory and may cause erosion. Undisturbed sites are rare, although there are a few excellent examples on protected lands in Florida. These forests contain some of the greatest floristic diversity of temperate forests in the U.S. and provide important habitat for many endemic species and species at their southern range limits (Kwit et al. 1998, Platt and Schwartz 1990).
