A0084 Eucalyptus spp. Ruderal Forest Alliance
Type Concept Sentence: This alliance consists of planted (and now abandoned) or naturalized groves of Eucalyptus species, of which there are at least nine species occurring in California: Eucalyptus camaldulensis, Corymbia citriodora, Eucalyptus cladocalyx, Eucalyptus globulus, Eucalyptus polyanthemos, Eucalyptus pulverulenta, Eucalyptus sideroxylon, Eucalyptus tereticornis, and Eucalyptus viminalis. Understories in groves of these fast-growing, long-lived trees are usually depauperate. This alliance is found throughout coastal mountains and the central valley of California into Baja California, Mexico.
Common (Translated Scientific) Name: Gum species Ruderal Forest Alliance
Colloquial Name: Ruderal Eucalyptus Grove
Hierarchy Level: Alliance
Type Concept: This alliance consists of planted (and now abandoned) or naturalized groves of Eucalyptus species. At least nine species occur in California: Eucalyptus camaldulensis, Eucalyptus cladocalyx, Eucalyptus globulus, Eucalyptus polyanthemos, Eucalyptus pulverulenta, Eucalyptus sideroxylon, Eucalyptus tereticornis, Eucalyptus viminalis, and Corymbia citriodora. Understories in groves of these fast-growing, long-lived trees are usually depauperate. A buildup of allelopathic chemicals in the soil and high volumes of debris inhibit establishment of other plants, though sometimes other non-natives, such as Hedera helix, or natives, such as Toxicodendron diversilobum, clamber extensively in stands. Seeds of Eucalyptus germinate when tree crowns and built-up debris are removed by fire or in other ways. Tree stumps sprout readily from the lignotuber when trees are felled. This alliance is found throughout coastal mountains and the central valley of California into Baja California, Mexico.
Diagnostic Characteristics: Eucalyptus globulus, Eucalyptus camaldulensis, or other gums are the dominant in the tree canopy.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Material for this description is from Sawyer et al. (2009). Further research on floristics is needed; what are dynamics between native and non-native components of riparian stands of Eucalyptus camaldulensis in San Diego and Riverside counties? What is relationship of this alliance to as-yet unsampled stands of Acacia cyclops, Acacia dealbata, Acacia longifolia, Acacia melanoxylon, and other Australasian species, which do invade coastal shrublands and woodlands?

Physiognomy and Structure: Tall, evergreen, broad-leaved trees can be as much as 8 m in height.
Floristics: This alliance consists of planted (and now abandoned) or naturalized groves of Eucalyptus camaldulensis, Corymbia citriodora (= Eucalyptus citriodora), Eucalyptus cladocalyx, Eucalyptus globulus, Eucalyptus polyanthemos, Eucalyptus pulverulenta, Eucalyptus sideroxylon, Eucalyptus tereticornis, and Eucalyptus viminalis. Understories in groves of these fast-growing, long-lived trees are usually depauperate.
Dynamics: Eucalyptus stands are highly flammable and have strongly modified the fire behavior of many urban/wildland interfaces in coastal California, resulting in severe and damaging fires. Eucalyptus camaldulensis has increased in cover in several riparian areas of coastal southern California and shares similar settings with native riparian trees such as Platanus racemosa (Evens and San 2006). Tree stumps sprout readily from the lignotuber when trees are felled (Skolmen and Ledig 1990, Esser 1993a, Boyd 2000, Bean and Russo 2005).
