Alnus serrulata - Xanthorhiza simplicissima Shrubland
Reference:
Southeastern Ecology Working Gro...
Description:
This association includes shrublands on rocky or gravelly substrates along narrow river margins in the southeastern Blue Ridge Escarpment gorges, ranging into the Cumberland Plateau. Vegetation composition, density, and height vary with frequency of flooding, substrate, and soil depth. The nominal shrubs are common and characteristic but not always dominant. Other shrubs may include Arundinaria gigantea, Diervilla sessilifolia, Salix nigra, Salix sericea, Rhododendron arborescens, Rhododendron viscosum, Rhododendron maximum, Rhododendron periclymenoides, Kalmia latifolia, Leucothoe fontanesiana, Cornus foemina, Cornus amomum, Itea virginica, and Viburnum nudum var. cassinoides. Arborescent species that occur as tall shrubs (or as occasional trees, less than 10% cover) include Acer rubrum, Carpinus caroliniana, Diospyros virginiana, Liquidambar styraciflua, Liriodendron tulipifera, Platanus occidentalis, and Tsuga canadensis. Open areas dominated by grasses and forbs include species such as Agrostis perennans, Boykinia aconitifolia, Carex torta, Holcus lanatus (exotic), Lycopus virginicus, Trautvetteria caroliniensis, Houstonia serpyllifolia, Impatiens capensis, Hypericum mutilum, Viola X primulifolia, and Eupatorium fistulosum. Adjacent alluvial forests in the Blue Ridge are dominated by Tsuga canadensis, Liriodendron tulipifera, Betula lenta, and, at lower elevations, below 600 m (2000 feet), Platanus occidentalis and Liquidambar styraciflua.
