CEGL003692 Heteromeles arbutifolia - Malosma laurina Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Toyon - Laurel Sumac Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association occurs on somewhat steep to very steep northeast- and northwest-facing slopes at low elevations between 50 and 584 m. It is characterized by a dominance of Heteromeles arbutifolia with a subdominance of Malosma laurina and several other species of lower average cover in the shrub layer. The herbaceous layer is not well-characterized. The emergent tree layer occasionally includes both Quercus agrifolia and Juglans californica.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Two other associations of the Heteromeles arbutifolia alliance have been described from western Riverside County (Klein and Evens 2006). They are the Heteromeles arbutifolia - Artemisia californica Association, where Artemisia californica codominates with Heteromeles arbutifolia in the shrub overstory, and the Heteromeles arbutifolia - Quercus berberidifolia - Cercocarpus betuloides - Fraxinus dipetala Association, where Quercus berberidifolia, Fraxinus dipetala, and Cercocarpus montanus var. glaber are characteristically present as codominant or subdominant shrubs. Borchert et al. (2004) describe a Heteromeles arbutifolia - Prunus ilicifolia Alliance from the Los Padres National Forest of southern and central coastal California. It has similarities with this association but has much higher average cover of Prunus ilicifolia.
