Name:
Solidago sempervirens - Juniperus horizontalis - Rhodiola rosea Coastal Rocky Headland Group
Reference:
NatureServe Biotics 2019
Description:
This group encompasses sparsely vegetated cliffs and shoreline outcrops along the North Atlantic Coast, primarily northeast of Penobscot Bay (Maine). Common species include <i>Achillea millefolium, Campanula rotundifolia, Festuca rubra, Plantago maritima, Prenanthes trifoliolata, Primula laurentiana</i>, and <i>Solidago sempervirens</i>. <i>Juniperus horizontalis</i> occurs in some locations and is indicative of the exposed coastal environment. In many locations, subarctic lithophilic plant species occur; these include <i>Euphrasia randii, Iris setosa, Lomatogonium rotatum, Rhodiola rosea</i>, and <i>Sagina nodosa ssp. borealis</i>. From Cobscook Bay east, <i>Dasiphora fruticosa ssp. floribunda</i> is also characteristic. Settings range from steep cliffs to nearly flat expanses of bedrock, all influenced by salt spray, frequent fog, and exposure to wind. Other sites include thin-soil areas, or cold-stressed sites. Dwarf heath-grassland is dominated by <i>Festuca rubra, Aronia melanocarpa, Symphyotrichum novi-belgii, Vaccinium angustifolium, Vaccinium vitis-idaea</i>, among others. Low coastal shrublands are <i>Gaylussacia baccata</i>- or <i>Gaylussacia dumosa</i>-dominated. Tall shrublands are dominated by <i>Alnus incana ssp. rugosa, Ilex mucronata, Aronia x prunifolia, Prunus pensylvanica</i>, and <i>Viburnum nudum</i>. <i>Gaylussacia baccata</i> and <i>Morella pensylvanica</i> occur in the understory. Common herbs include <i>Pteridium aquilinum var. latiusculum, Trientalis borealis</i>, and <i>Maianthemum canadense</i>.
