Baccharis pilularis / Annual Grass-Herb Shrubland | NatureServe Biotics 2019
click to update datacart
Name: Baccharis pilularis / Annual Grass-Herb Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland association of northern to southern coastal California occurs on gentle valley bottoms to steep slopes with flat to variable aspect at low elevations between 1 and 568 m. It is characterized by the dominance of <i>Baccharis pilularis</i> in the shrub layer and a variety of non-native, largely annual grasses and herbs in the herbaceous layer. The herbaceous understory can be dominated by annual exotic grasses such as <i>Lolium perenne ssp. multiflorum, Bromus hordeaceus, Bromus diandrus</i>, and <i>Avena barbata</i>, along with annual herbs such as <i>Raphanus sativus</i>. Other native herbaceous species include <i>Distichlis spicata, Juncus </i>spp., <i>Muhlenbergia rigens</i>, and <i>Corethrogyne filaginifolia</i>. The emergent tree layer includes occasional ruderal trees such as <i>Schinus molle, Eucalyptus</i> spp., and <i>Phoenix canariensis</i>, as well as the native <i>Quercus agrifolia</i>. This association is indicative of a disturbed seral stage that typically comes following the reversion of cleared pastureland or non-native grassland back to shrubland. <i>Baccharis pilularis</i> behaves similarly in other areas of northern California where it often forms the first wave of woody species to recolonize cleared land.  Accession Code: urn:lsid:vegbank.org:commConcept:32066-{9941BA3A-4D4C-43A5-AEC4-FEFC3AEB9F62} Plot-observations of this Community Concept: 23
