CEGL001567 Festuca rubra Coastal Headland Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Fescue Coastal Headland Grassland
Colloquial Name: Coastal Headland Red Fescue Grassland
Hierarchy Level: Association
Type Concept: This association is found along the Pacific Northwest coast. It occupies coastal headlands on extreme sites, usually with moderate to steep slopes of southerly aspects. These headlands are composed of bedrock of conglomerates (Washington) and basalts (Oregon). The soils can be derived from colluvium or sands, are usually shallow and well-drained, and often have a significant component of gravels. Persistent strong winds, salt-spray, and the shallow soils are important factors in the maintenance of these grasslands. This is an herbaceous community dominated by the perennial grass Festuca rubra, and with a rich forb component. Festuca rubra forms large, loose clumps from long, slender rhizomes, and has cover ranging from as low as 10% to over 70%. Associated perennial grasses may include Elymus glaucus, Festuca idahoensis, Danthonia californica, Calamagrostis nutkaensis, and Koeleria macrantha. Important forbs include Artemisia suksdorfii, Camassia leichtlinii, Viola adunca, Erigeron glaucus, Achillea millefolium, Eriophyllum lanatum, and Solidago canadensis. Trees from nearby forested areas may invade in the absence of fire; these include the conifers Pseudotsuga menziesii, Pinus contorta, and Picea sitchensis, and the broad-leaved Quercus garryana or Arbutus menziesii.

Floristics: This association is poorly described, but has recently been the subject of inventory efforts in Washington. It is an herbaceous community dominated by the perennial grass Festuca rubra, and with a rich forb component. Festuca rubra forms large, loose clumps from long, slender rhizomes, and has cover ranging from as low as 10% to over 70%. Associated perennial grasses may include Elymus glaucus, Festuca idahoensis, Danthonia californica, Calamagrostis nutkaensis, and Koeleria macrantha. Important forbs include Artemisia suksdorfii, Camassia leichtlinii, Viola adunca, Erigeron glaucus, Achillea millefolium, Eriophyllum lanatum, and Solidago canadensis. Trees from nearby forested areas may invade in the absence of fire; these include the conifers Pseudotsuga menziesii, Pinus contorta, and Picea sitchensis, and the broad-leaved Quercus garryana or Arbutus menziesii.
The Oregon silverspot butterfly (Speyeria zerene hippolyta), a Federally listed threatened species, utilizes Viola adunca as its primary food source. This perennial forb grows in meadows established on rocky headlands, such as those dominated by Festuca rubra. Most, if not all, stands of this association are dominated by introduced and exotic species as a result of severe impacts from livestock grazing. Common species of this type include the grasses Holcus lanatus, Bromus hordeaceus (= Bromus mollis), Agrostis gigantea (= Agrostis alba), Aira praecox, and Poa pratensis, and the forbs Senecio jacobaea, Trifolium repens, and Cirsium spp.

Dynamics: No Data Available
Environmental Description: This coastal headland grassland association is found along the Pacific Northwest coast, from central Oregon north to the Puget Sound region. The climate is strongly marine, with persistent onshore (westerly) winds, high annual precipitation, and moderate temperatures. Summer months typically are relatively dry.
This association occupies coastal headlands on extreme sites, usually with moderate to steep slopes of southerly aspects. These headlands are composed of bedrock of conglomerates (Washington) and basalts (Oregon). The soils can be derived from colluvium or sands, are usually shallow and well-drained, and often have a significant component of gravels. Persistent strong winds, salt spray, and the shallow soils are important factors in the maintenance of these grasslands.

Geographic Range: Festuca rubra Coastal Headland Herbaceous Vegetation is a component of the Coastal Prairie and potentially inhabits a small portion of the range of Coastal Prairie, from northern California north to the Puget sound region.
