Forest Investment Account, Innovative Project No. SC 6738004, was undertaken to monitor the spread and infection of young western hemlock (Tsuga heterophylla [Raf.] Sarg.) in coastal British Columbia retention-harvested forests by western hemlock dwarf mistletoe (Arceuthobium tsugense (Rosendahl) G.N. Jones subspecies tsugense). The goal of the monitoring is to develop methods and provide baseline data that facilitates sustainable management of retentionharvested, mistletoe-infested coastal forests. Helicopter, boat and vehicle were used to survey prospective areas in the Sunshine Coast TSA. Three monitoring plots were established near Sechelt and north of Powell River, with 1 to 10 per cent of young trees infested. Monitoring plots at block UC5C near Ucluelet were re-inspected and very little new infestation was found. A summary of previous results to March 31, 2008 is provided.
