HabitatsKey communities are alluvial forest remnants, waste places, shrublands, open stream systems and particularly coastal areas. Widespread and common, especially near towns. Sometimes locally abundant. A common farm hedging plant.
Impact to Biota and EcosystemsMay displace the shrub tier and marginal shrubs of alluvial forests. May displace shrubs in regenerating communities and remain persistent in these areas.
Dispersal Routes, Vectors, Infestation SourcesOriginally spread from domestic hedges, dispersed by birds, and is now spreading in farm hedges, along roadsides, streamsides, wastelands and disused railway lines. They are bulking-up in these areas as well as in fenced off and unmodified forest remnants.
