Name: Quercus garryana Shrubland Alliance Reference: Western Ecology Working Group of... Description: Stands of this foothill and montane California shrubland alliance are found at higher elevations than most other chaparrals. Elevations range from 600-1800 m. Sites tend to be cooler and moister due to these higher elevations. Annual precipitation is quite seasonal, with the bulk falling between November and April. Yearly precipitation totals vary from 60 cm in the south to over 120 cm in the north. Summers are very warm and dry; winters are cool and moist. Stands are usually found on upper slopes; often these are steep. Soils are thin. This shrubland is dominated by Quercus garryana var. breweri. Emergent conifers, such as Abies concolor or Picea breweriana, may be present, as well as individuals of Quercus garryana var. garryana or Quercus kelloggii. Shrubs present may include Arctostaphylos patula, Arctostaphylos nevadensis, Quercus vacciniifolia, Ceanothus cordulatus, Ceanothus velutinus, and Ceanothus cuneatus. Festuca californica may be present in the herbaceous layer.  Accession Code: VB.CC.19537.QUERCUSGARRYANA Plot-observations of this Community Concept: 1
