This alliance is found on dune systems in the Great Lakes region of the United States and Canada. The canopy is very open, ranging from 5-25%, with little subcanopy or shrub layer. Populus deltoides is the dominant species, though Tilia americana, Fraxinus pennsylvanica, and other species may be present. The ground layer is dominated by exposed sand, with a scattered herbaceous layer. Typical associates include Schizachyrium scoparium, Ammophila breviligulata, Sporobolus cryptandrus, and Poa compressa. |

Piedmont Acidic Cliff Vegetation

This sparsely vegetated cliff association occurs in the Piedmont of the southeastern United States. Examples are found on steep to vertical outcrops of acidic substrates, in topographically low settings such as river bluffs that are not subject to flood scouring. Substrates may include various felsic igneous or metamorphic rocks, acidic saprolite, and occasionally unconsolidated acidic sediments. Vegetation is low in cover, and is confined to lichens and plants growing on bare rock and to sparse herbs, shrubs, and trees rooted in local pockets of deeper soil. The flora is a mix that usually includes drought-tolerant, shade-intolerant species, species shared with surrounding forests, and sometimes local occurrences of wetland species associated with small seepage zones. Most of the species are acid-tolerant, and more basophilic species are largely absent. Lichens and bryophytes may be abundant or scarce. |

NY Heritage: Salt shrub

accession code: VB.CC.28743.NYHERITAGESALTS

A shrubland community that forms the ecotone between salt marsh and upland vegetation. Salinity levels are generally lower here than in the salt marsh (soil pore salinity ranges 7 ppt to 27 ppt); and the elevation is higher. Salt shrub does not usually develop on deep peat. More often, it occurs on a thin (0-10 cm) layer of peat, and soils share characteristics of both estuarine and maritime terrestrial settings. Periodic disturbance associated with storms causes die-back of shrubs.
Characteristic shrubs are groundsel-tree (Baccharis halimifolia), saltmarsh-elder (Iva frutescens), and pasture rose (Rosa carolina); salt-meadow grass (Spartina patens), black-grass (Juncus gerardii), and switchgrass (Panicum virgatum) are typical herbs. Salt shrub is almost always dominated by Iva frutescens on the marshward edge of the community, often forming a stunted leading edge of the community. Baccharis halimifolia only becomes more dominant in the older, more developed, landward side. The landward side of salt shrub is usually the most diverse. A characteristic animal is marsh wren (Cistothorus palustris).
Salt shrub is usually present as a linear feature at the upper edge of a salt marsh marking the limit of the highest spring and storm tides within a given estuarine basin. In areas where the local topography is nearly level an extensive shrubland or brackish meadow may occur. |
