Name: Ammophila breviligulata - Uniola paniculata - Solidago sempervirens Dune & Grassland Macrogroup Reference: NatureServe Biotics 2019 Description: This macrogroup encompasses coastal grasslands and shrublands along the Great Lakes, Lake Champlain, and Atlantic and Gulf coasts, occurring on sandy dunes and beaches along coastal shorelines and barrier islands, as well as on rocky headlands in the North Atlantic. It includes areas ranging from sparsely vegetated to lichen-dominated to grasslands and grassland-shrub complexes depending upon the degree of deposition, erosion, and distance from shore. Species composition varies geographically. Within the Great Lakes region and along the North Atlantic Coast, <i>Ammophila breviligulata</i> characterizes most herbaceous stands. <i>Schizachyrium scoparium</i> is common in many of these northern (not in Canada) sites as well. Common shrubs include <i>Arctostaphylos uva-ursi, Hudsonia tomentosa, Juniperus communis</i>, and <i>Juniperus horizontalis</i>. Some examples in the Great Lakes may also have a scattered overstory canopy dominated by <i>Pinus banksiana, Pinus resinosa</i>, and/or <i>Pinus strobus</i>, and on the Atlantic Coast, <i>Pinus rigida</i> or <i>Pinus taeda</i>. Along the Atlantic Coast <i>Morella pensylvanica</i> shrublands are common, and dwarf-shrubs include <i>Empetrum nigrum</i> or, less commonly, <i>Corema</i>. <i>Solidago sempervirens</i> is typical on Atlantic coastal sites. <i>Uniola paniculata</i> is diagnostic within sites along the South Atlantic Coast. <i>Panicum amarum</i> occurs on the foredunes, and <i>Spartina patens</i> and <i>Schizachyrium littorale</i> are common on the older dunes and sand flats. Soils are typically well-drained to excessively drained sands with little to no horizon development, or a thin patchy layer of organic material on rocky headlands. Heavy winds significantly impact these communities which can cause reworking of sand or by slower eolian processes. Sites along the Atlantic Coast are shaped by salt spray, overwash, and very high humidity. Fire suppression in the range of this macrogroup can cause an increase in woody species. Many areas have also been impacted by agriculture and grazing.  Accession Code: urn:lsid:vegbank.org:commConcept:40476-{1933FFEA-45BB-4364-95C1-8D671881F2DA} Plot-observations of this Community Concept: 0
