Name: Baccharis halimifolia - Iva frutescens / Panicum virgatum Shrubland Reference: Eastern Ecology Working Group of... Description: This maritime shrubland of the eastern states occurs in association with salt marshes, occurring along the upper edges of the marsh, at the transition to uplands. <i>Iva frutescens</i> is the most characteristic and dominant shrub species, and <i>Baccharis halimifolia</i> is a common associate. Other associated shrubs include <i>Morella pensylvanica (= Myrica pensylvanica)</i> in the northern portion of the range, while <i>Borrichia frutescens, Morella cerifera (= Myrica cerifera)</i>, and <i>Juniperus virginiana var. silicicola</i> are frequent associates in the southern part of the range. <i>Spartina patens</i> is a characteristic and usually abundant grass; other common herbaceous associates include <i>Panicum virgatum, Distichlis spicata, Hibiscus moscheutos, Toxicodendron radicans, Teucrium canadense, Festuca rubra, Limonium carolinianum, Atriplex prostrata, Sabatia stellaris, </i><i>Solidago sempervirens, </i><i>Sabatia dodecandra</i>, and in the north <i>Hierochloe odorata</i> and <i>Juncus gerardii</i>, and in the south <i>Setaria parviflora</i>. This community often forms an abrupt transition from salt marsh to upland reflecting the relatively higher elevation and less frequent tidal flooding. Shrub cover in this situation tends to be fairly dense, and herbs are sparsely distributed. Storm-induced disturbance causes periodic die-back of the shrubs restricting the extent of their spread.  Accession Code: VB.CC.31405.CEGL003921 Plot-observations of this Community Concept: 0
