Skunk cabbage: Biological control using co-evolved, host specific herbivores
Overall effectiveness category Awaiting assessment
Number of studies: 0
Background information and definitions
One-off introduction of a co-evolved, host-specific species from the area of origin of the invasive pest can potentially provide sustainable control without affecting non-target native plants. In its native range, skunk cabbage Lysichiton americanus is eaten by black tailed deer Odocoileus hemionus (Gillingham et al. 1997) and by Grizzly bear Ursus arctos (Gyug et al. 2004). However, the fruits and seeds have not been reported to be eaten by animals in its introduced range (EPPO 2009).
