Name: (Buddleja utahensis, Eriogonum heermannii) - Gutierrezia spp. Limestone Scrub Reference: NatureServe Biotics 2019 Description: This association is found in the southern Great Basin in California where it forms an open shrub canopy (3-13% cover) that is characterized by the presence of <i>Eriogonum fasciculatum</i> with <i>Buddleja utahensis, Eriogonum heermannii</i>, and/or <i>Gutierrezia microcephala</i> dominant or codominant. It also occurs scattered in other limestone-rich, rocky areas of the eastern Mojave Desert of California. Other shrubs may be present, including <i>Brickellia microphylla, Echinocactus polycephalus, Prunus fasciculata</i>, and <i>Scopulophila rixfordii</i>. Herbaceous cover is generally sparse and ranges from 0.2 to 9% with common associated species <i>Achnatherum speciosum, Aristida purpurea</i>, and exotic <i>Bromus rubens</i>. Occasional emergent <i>Yucca brevifolia</i> trees may be present with up to 0.5% cover. Biological soil crusts are often present and are composed of lichens and mosses. Stands occur scattered along steep, calcareous bedrock areas at mid to upper elevations (950-1900 m). Sites are found primarily on midslopes with somewhat steep to very steep (17-65°) slopes on cooler northwesterly to easterly aspects. Soils are usually sandy loams derived from sedimentary substrates, such as limestone and dolomite.  Accession Code: urn:lsid:vegbank.org:commConcept:37442-{99A9A349-D4A3-4721-A9A2-74C11B64A3CA} Plot-observations of this Community Concept: 0
