Name:
Arctostaphylos viscida - Arctostaphylos myrtifolia - Arctostaphylos manzanita Chaparral Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance consists of chaparral dominated by <i>Arctostaphylos viscida, Arctostaphylos viscida ssp. pulchella, Arctostaphylos manzanita</i>, or <i>Arctostaphylos myrtifolia</i>. They do not occur together and can occur as monotypic stands. However, each also occurs as mixed shrub stands with codominants of other species such as <i>Adenostoma fasciculatum, Amelanchier alnifolia, Arctostaphylos mewukka, Arctostaphylos patula, Baccharis pilularis, Ceanothus cordulatus, Ceanothus cuneatus, Ceanothus integerrimus, Ceanothus velutinus, Eriodictyon californicum, Frangula californica ssp. tomentella, Garrya fremontii, Heteromeles arbutifolia, Holodiscus discolor, Quercus berberidifolia</i>, and <i>Quercus wislizeni</i>. Emergent <i>Pinus attenuata, Pinus ponderosa, Pinus sabiniana, Pseudotsuga menziesii</i>, or <i>Quercus douglasii</i> trees may be present. Tree layer is sparse. Shrubs are <4 m in height, their canopy continuous or intermittent. The herbaceous layer is sparse and may include <i>Lotus scoparius</i>. All three occur in similar habitats of ridges and upper slopes that may be steep. Soils are shallow and are developed from ultramafic, weathered clays, sandstone, or granitic substrates. Elevation ranges from 100 to 1850 m. These shrublands are adapted to high-intensity, long-interval fires (~50 years or longer). Infrequent fires may result in conversion to other shrub types or invasion by trees.
