Name: Artemisia pycnocephala - Cardionema ramosissimum Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland association is currently only known from Point Reyes National Seashore in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Other stands of <i>Artemisia pycnocephala</i>-dominated coastal dune vegetation occur from Humboldt County to at least Monterey County in California. Stands of this association are found on sandy substrates along beaches and in dune fields. Slopes are gentle and aspects are generally northwest. Stands are currently small, usually less than 2 acres in size. They occupy dune slopes and ridges most commonly along North Beach on the Point Reyes Peninsula. The non-native invasive species <i>Ammophila arenaria</i> and <i>Carpobrotus edulis</i> are threatening to invade many stands of this association. This short-shrub association is dominated by <i>Artemisia pycnocephala</i> which consistently contributes about 20% cover to the subshrub canopy. <i>Carpobrotus edulis</i> (exotic) dominates the herbaceous layer, while <i>Cardionema ramosissimum</i> is present at lower cover. Emergent individuals of <i>Ericameria ericoides</i> up to 1 m in height usually contribute minor cover. Other common subshrub associates may include <i>Lotus scoparius, Eriogonum latifolium, Grindelia stricta var. stricta</i>, and/or <i>Grindelia stricta var. platyphylla</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:32065-{C976EDBE-21E8-4127-A872-22FA9A5C4EFD} Plot-observations of this Community Concept: 0
