Species Summary

This tall, large-leafed perennial occurs from southern Oregon to southern British Columbia, where it is confined to the Chilliwack River Valley. It grows in the understory of moist, mature mixed forests and is most commonly associated with bigleaf maple (Acer macrophyllum). Populations range in size from 1 to 63 plants, germination rates are low and it is a poor disperser. The largest threat to the species is habitat loss and fragmentation due to commercial logging. For more information on the biology and management of this species, see its entry in the province's Accounts and Measures for Managing Identified Wildlife.
