G801 Vancouverian Ruderal Forest Group
Type Concept Sentence: This group consists of stands of native and exotic species that establish on soil disturbed sites or of naturalized stands of non-native tree species that have escaped from cultivation, reside in abandoned plantations, were deliberately planted or have otherwise become naturalized on upland sites; dominant non-native species include Acer platanoides, Crataegus arborea, Ilex aquifolium, Ilex crenata, Pinus nigra, Pinus sylvestris, or Prunus padus.
Common (Translated Scientific) Name: Vancouverian Ruderal Forest Group
Colloquial Name: Vancouverian Ruderal Forest
Hierarchy Level: Group
Type Concept: This group has either a mix of native and exotic species that establish on soil disturbed sites or of non-native tree species that have escaped cultivation, dominate abandoned plantations or have otherwise become naturalized. These stands are not abundant or even common, but they are certainly present and may increase with climate warming and further human disturbances across the landscape. Non-native species include Acer platanoides, Crataegus arborea, Ilex aquifolium, Ilex crenata, Pinus nigra, Pinus sylvestris, or Prunus padus. Characteristics of native species that occupy disturbed sites needs further review. Habitats range from sand dunes to old fields, often are present due to some type of severe disturbance or deliberate planting. Most stands are near current or past human habitations. They occur in Oregon, Washington and southern British Columbia.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Currently, description includes stands dominated by non-native tree species. But the concept of ruderal forests could include old-field or other sites with severe soil disturbance that may have a ground layer of exotic shrubs and herbs with a generalist or "weedy" native overstory.

Floristics: No information is available other than dominance in the upper canopy by non-native tree species which may include Acer platanoides, Crataegus arborea, Ilex aquifolium, Ilex crenata, Pinus nigra, Pinus sylvestris, and Prunus padus, among others.
Dynamics: No Data Available
Environmental Description: These forests are uncommon in the Pacific Northwest. They can occur on various upland soil conditions. In Oregon, Pinus nigra and Pinus sylvestris occur on sand dunes and were planted as a soil erosion measure. In Washington and British Columbia, small stands of various species occur near human habitation.
Geographic Range: This group occurs in Oregon, Washington and southern British Columbia,
