A3231 Pinus taeda - Liriodendron tulipifera - Liquidambar styraciflua Ruderal Forest Alliance

Type Concept Sentence: This alliance includes semi-natural forests of Pinus taeda, which develop following cropping or site conversion, often found with a wide range of hardwood species, including Acer rubrum, Carya spp., Cornus florida, Juniperus virginiana var. virginiana, Liquidambar styraciflua, Liriodendron tulipifera, Nyssa sylvatica, Pinus virginiana, Prunus serotina var. serotina, Quercus alba, Quercus stellata, Quercus velutina, Ulmus alata, and Ulmus rubra.


Common (Translated Scientific) Name: Loblolly Pine - Tuliptree - Sweetgum Ruderal Forest Alliance

Colloquial Name: Ruderal Loblolly Pine - Tuliptree - Sweetgum Forest

Hierarchy Level:  Alliance

Type Concept: This alliance includes semi-natural forests of Pinus taeda, which develop following cropping or site conversion. Other canopy and subcanopy species that may be present in semi-natural stands are Acer rubrum, Carya spp., Cornus florida, Juniperus virginiana var. virginiana, Liquidambar styraciflua, Liriodendron tulipifera, Nyssa sylvatica, Pinus virginiana, Prunus serotina var. serotina, Quercus alba, Quercus stellata, Quercus velutina, Ulmus alata, and Ulmus rubra. In the shrub layer, Vaccinium spp., especially Vaccinium stamineum, are common in these forests. Vines and lianas are always present in abundance, especially Vitis rotundifolia. The herbaceous layer may be sparse, particularly if shrubs and vines are dense, but Chasmanthium laxum may be fairly abundant in this community. Other herbs include Panicum amarum var. amarulum, Eupatorium hyssopifolium, and Elephantopus nudatus. In southern Virginia and North Carolina, Quercus virginiana and Gelsemium sempervirens may also be present.

Diagnostic Characteristics: Stands are strongly dominated by Pinus taeda (>80%), or if >25%, then only weedy native hardwood associates also occur, including Acer rubrum, Juniperus virginiana var. virginiana, Liquidambar styraciflua, Liriodendron tulipifera, Pinus virginiana, and Prunus serotina var. serotina. The ground layer has a mix of exotic shrubs and herbs, and generalist native species.

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: One association (CEGL003618) needs review. These are woodlands with semi-open to very open canopies composed of Pinus taeda, with or without Pinus echinata. The structure and composition of this community are maintained by fires set by military training; the relationship of this vegetation to naturally occurring vegetation is not completely clear.

Physiognomy and Structure: Stands are strongly conifer-dominated.

Floristics: This alliance includes semi-natural forests of Pinus taeda, which develop following cropping or site conversion. Other canopy and subcanopy species that may be present in semi-natural stands are Acer rubrum, Carya spp., Cornus florida, Juniperus virginiana var. virginiana, Liquidambar styraciflua, Liriodendron tulipifera, Nyssa sylvatica, Pinus virginiana, Prunus serotina var. serotina, Quercus alba, Quercus stellata, Quercus velutina, Ulmus alata, and Ulmus rubra. In the shrub layer, Vaccinium spp., especially Vaccinium stamineum, are common. Vines and lianas are always present in abundance; Vitis rotundifolia is most commonly present, but Parthenocissus quinquefolia, Smilax glauca, Smilax rotundifolia, and Toxicodendron radicans are usually present in abundance as well. The herbaceous layer may be sparse, particularly if shrubs and vines are dense, but Chasmanthium laxum may be fairly abundant in this community. Other herbs include Panicum amarum var. amarulum, Eupatorium hyssopifolium, and Elephantopus nudatus. In southern Virginia and North Carolina, Quercus virginiana and Gelsemium sempervirens may also be present, but Quercus virginiana is never abundant and, when present, is usually restricted to the understory. Pinus taeda may occur rarely in the Ouachita Mountains and Ozarks of Arkansas where the species is becoming naturalized, expanding from its native range in the Coastal Plain, where it naturally occurs in low, moist areas (e.g., deep, well-drained soils of floodplains). However, a natural Pinus taeda forest association is not recognized for the Ozarks or Ouachita region.
