Name: Baccharis halimifolia - Iva frutescens / Spartina patens Shrubland Reference: Eastern Ecology Working Group of... Description: This maritime shrubland of the mid-Atlantic states occurs in association with salt marshes. In its natural condition, this community forms the ecotone between the high salt marsh and adjacent upland vegetation. It also occurs in patches on areas of slightly higher elevation within the salt marsh or on spoil mounds adjacent to ditches. Baccharis halimifolia and Iva frutescens are the most characteristic and dominant shrub species. Other associated shrubs include Morella pensylvanica (= Myrica pensylvanica) in the northern portion of the range, while Borrichia frutescens, Morella cerifera (= Myrica cerifera) and Juniperus virginiana var. silicicola are frequent associates in the southern part of the range. Spartina patens is a characteristic and usually abundant grass; other common herbaceous associates include Panicum virgatum, Distichlis spicata, Hibiscus moscheutos, Toxicodendron radicans, Teucrium canadense, Festuca rubra, Limonium carolinianum, Atriplex prostrata, Sabatia stellaris, Sabatia dodecandra, and in the north Hierochloe odorata and Juncus gerardii, and in the south, Setaria parviflora. 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. Where the topographic relief is more gradual, the community is characterized by an open and relatively evenly spaced shrub stratum with a well-developed herbaceous layer, reflecting an intergrading of this community with the adjacent high salt marsh. Storm-induced disturbance causes periodic die-back of the shrubs restricting the extent of their spread.  Accession Code: VB.CC.28402.BACCHARISHALIMI Plot-observations of this Community Concept: 0
