Species Summary

This small slug (20 mm), which actually jumps when disturbed, is found from Oregon to British Columbia, where it is confined to southern Vancouver Island.  The warty jumping slug inhabits a variety of moist forest and riparian habitats at low to middle elevations. Abundant woody debris and leaf litter are important for cover and the slugs are frequently encountered at the base of sword ferns. Population size and trends are unknown, but distribution is patchy and much apparently suitable habitat is not occupied. Habitat degradation, loss and fragmentation due to urbanization and clear-cut logging have occurred over much of its Canadian range and continue to be the greatest threat to the species. The low number of scattered populations increases its vulnerability.
