Name:
Quercus lyrata - (Carya aquatica) Seasonally Flooded Forest Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
Quercus lyrata is dominant or codominant in stands of this alliance. There is often substantial Carya aquatica, especially in the wetter sites where no other canopy species occur. Less wet occurrences of this alliance will have substantial Liquidambar styraciflua, as well as Quercus texana within its range. Species composition varies with geography, but characteristic species include Quercus laurifolia, Fraxinus pennsylvanica, Carpinus caroliniana, Fraxinus profunda, Taxodium distichum, Planera aquatica, Populus heterophylla, Celtis laevigata, Diospyros virginiana, Acer rubrum, Quercus phellos (sometimes codominant to dominant), and occasionally Ulmus americana, Nyssa sylvatica, Quercus michauxii, and Quercus palustris. Common understory and shrub associates include Ilex decidua, Crataegus viridis, Cornus foemina (= Cornus stricta), Forestiera acuminata, Carpinus caroliniana, and Cephalanthus occidentalis. Species composition and density of the herbaceous stratum vary with geography and frequency of flooding. Common species in this layer include Justicia ovata, Saururus cernuus, Leersia lenticularis, Mikania scandens, Lobelia cardinalis, Ludwigia palustris, Diodia virginiana, Gratiola virginiana, Carex joorii, Carex intumescens, Symphyotrichum lateriflorum (= Aster lateriflorus), Boehmeria cylindrica, and Pilea pumila. The exotic Ludwigia grandiflora (= Ludwigia uruguayensis) may be common in examples of this alliance. Some occurrences in Arkansas have Gleditsia aquatica, Liquidambar styraciflua, Acer rubrum, Acer saccharinum, and Diospyros virginiana. Shrubs include Planera aquatica, Styrax americanus, Cornus foemina, and Cephalanthus occidentalis. Vines are common and species include Lonicera japonica (exotic), Vitis palmata, and Cardiospermum halicacabum. Forests of this alliance occur on heavy clay soils of the Orders Ultisol and Vertisol on low, wet, seasonally flooded floodplains, shallow sloughs with relatively little water flow, and in depressions.
