CEGL003705 Diplacus aurantiacus Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Orange Bush-monkeyflower Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland is known from southern and central interior coastal mountains of California. It occurs on abrupt, somewhat steep to steep slopes with variable aspect at low elevations between 43 and 657 m (141-2155 feet). Soils are sand to silt loams, on volcanic, sedimentary, and colluvial parent materials. Slopes are often unstable, or recently burned, or a product of recent land- or rockslides. It is characterized by a strong dominance of Diplacus aurantiacus in the shrub layer. It has a presence of Leymus condensatus, Selaginella bigelovii, and Bromus diandrus in the herbaceous layer of many stands, but none are consistently present. The emergent tree layer is usually absent but may include Juglans californica, Eucalyptus sp., Pinus sp., Quercus agrifolia, and Platanus racemosa.

Floristics: This association is characterized by a strong dominance of Diplacus aurantiacus (= Mimulus aurantiacus) in the shrub layer. Other shrubs present may include Artemisia californica, Malosma laurina, Adenostoma fasciculatum, Prunus ilicifolia ssp. ilicifolia, Arctostaphylos glauca, Salvia leucophylla, Toxicodendron diversilobum, Sambucus nigra ssp. cerulea (= Sambucus mexicana), and Eriogonum fasciculatum var. foliolosum. It has a presence of Leymus condensatus, Selaginella bigelovii, and Bromus diandrus in the herbaceous layer of many stands, but none are consistently present. The emergent tree layer is usually absent but may include Juglans californica, Eucalyptus sp., Pinus sp., Quercus agrifolia, and Platanus racemosa at low cover.
Dynamics: No Data Available
Environmental Description: It appears on generally steep, often somewhat unstable slopes in relatively mesic settings within the general vicinity of stands of Artemisia californica or Salvia leucophylla alliances. It also appears to be closely associated with recent burns in many cases. In some cases, this type also appears to be associated with natural ground disturbance such as rockslides. This shrubland association occurs on abrupt, somewhat steep to steep slopes with variable aspect at low elevations between 43 and 657 m (141-2155 feet). Soils are sand to silt loams, on volcanic, sedimentary, and colluvial parent materials.
Geographic Range: This association is known from the Santa Monica Mountains region and interior Central Coast Ranges (Pinnacles National Monument). Small stands have been seen as far north as Contra Costa County (T. Keeler-Wolf pers. obs. 2005). These also occur on steep slopes and include Artemisia californica. It is likely to occur throughout much of cismontane central and southern California.
