Southeastern Ecology Working Gro...
Description:
This witch-hazel - dogwood gravel wash occurs in the Ozarks-Ouachita region of the United States. This shrubland occurs as narrow strips (1-10 m wide) in the upper scour zones of small to medium-sized streams. It is typically found in a substrate of loose cobble, but on larger streams and rivers may occur on bedrock shelves or alluvial silt, where it intergrades with other vegetation types. Hamamelis vernalis, Cornus obliqua (= Cornus amomum ssp. obliqua), and Hypericum prolificum are common and characteristic. Several other species may be locally abundant in the diverse microhabitats of this shrubland, including Salix caroliniana in more open streambeds, Leptopus phyllanthoides (= Andrachne phyllanthoides) in drier scour zones, Juniperus virginiana var. virginiana in upper scour zones, Ilex vomitoria on bedrock and boulders on larger streams, and Alnus serrulata and Cephalanthus occidentalis in low, wet areas. On more stable substrates Platanus occidentalis, Acer rubrum, and Liquidambar styraciflua may be locally abundant. Other shrub and tree species that may occur include Amorpha fruticosa, Amorpha ouachitensis, Betula nigra, Crataegus spp., Diospyros virginiana, Ulmus alata, Hypericum prolificum, Ilex decidua, Styrax grandifolius, and Vaccinium virgatum. Herbaceous species include Amsonia illustris, Amsonia hubrichtii, Ambrosia spp., Apios americana, Boltonia diffusa, Chasmanthium latifolium, Commelina erecta, Diodia virginiana, Eupatorium fistulosum, Ludwigia decurrens, Polygonum pensylvanicum, Vernonia lettermannii, Panicum virgatum, Panicum anceps, and Perilla frutescens (exotic). Trachelospermum difforme is a common vine of this community.
