Name:
Acer rubrum var. trilobum / Alnus serrulata / Calamagrostis coarctata Seep Woodland
Reference:
NatureServe Biotics 2019
Description:
This association includes open acidic seeps found on broad sandstone ridges in the Appalachian Plateau of Kentucky and Tennessee. This open woodland seep association has a very open canopy containing <i>Acer rubrum, Ilex opaca var. opaca, Oxydendrum arboreum</i>, and <i>Kalmia latifolia</i>. Some areas lack a canopy and are dominated by shrubs or herbs. Shrubs include <i>Alnus serrulata, Aronia melanocarpa, Ilex verticillata</i>, and <i>Itea virginica</i>. Ferns and sedges are locally dominant and <i>Sphagnum</i>-dominated pockets are common with <i>Sphagnum palustre</i> typical. Herbs include <i>Carex atlantica, Carex stricta, Carex bromoides ssp. bromoides, Carex leptalea, Chasmanthium laxum</i> (on margins), <i>Osmunda cinnamomea, Osmunda regalis var. spectabilis, Thelypteris noveboracensis, Woodwardia areolata, Lygodium palmatum, Scirpus cyperinus, Dichanthelium oligosanthes var. scribnerianum, Rhexia</i> spp., <i>Mimulus</i> spp., <i>Eutrochium fistulosum</i>, and <i>Lycopodiella appressa</i>. Other species known from these seeps include <i>Platanthera cristata, Platanthera integrilabia, Platanthera ciliaris, Platanthera clavellata, Isoetes engelmannii, Xyris torta, Calopogon tuberosus, Calamagrostis coarctata, Sphenopholis pensylvanica, Vernonia noveboracensis, Hypericum crux-andreae, Bartonia virginica</i>, and <i>Rhynchospora globularis</i>. Fire frequency, as well as tree-fall due to saturated soils, may play a role in keeping the canopy open.
