Name: Alnus maritima ssp. maritima / Acorus calamus Shrubland
Reference: Eastern Ecology Working Group of...
Description: This tidal shrubland of the Maryland portion of the Delmarva peninsula on the central Atlantic Coast occurs on freshwater tidal rivers and tributaries. Waters are generally oligohaline, but may receive pulses of higher salinities during spring high tides or low river discharge. The vegetation occurs on the ecotones between freshwater tidal marshes and tidal swamps. Hummocks and hollows are characteristic, and the substrate is poorly drained, slightly acidic tidal muck with silts, fine sands and partially decomposed peat admixed. The shrub canopy is well-developed, often dense, and dominated by <i>Alnus maritima</i>. Associated shrub species are few and at low cover, but may include <i>Viburnum dentatum, Cornus amomum,</i> or <i>Rosa palustris</i>. Vines may include <i>Toxicodendron radicans, Apios americana</i>, and <i>Mikania scandens. </i>The herbaceous layer is dominated by <i>Acorus calamus</i>, with other associates including <i>Impatiens capensis, Peltandra virginica, Polygonum sagittatum, Polygonum punctatum, Cicuta maculata, Cuscuta gronovii, Cinna arundinacea, Polygonum arifolium, Galium obtusum</i>, and <i>Thalictrum pubescens (= Thalictrum polygamum)</i>.
