Possibly evidence of an infestation in Ft Smith region in 2013 (H274); White-spotted sawyer beetle (Monochamus scutellatus) (WSSB) complex – previously described in the 2015 Forest Health Report. Water-stressed mature pine stands near Checkpoint (Dehcho) were attacked by a complex of insects with WSSB being the main pest. Another spruce leading stand near Jean-Marie River was suspected to be affected by WSSB complex as well. The affected area expanded from 767 ha in 2015 to over 2000 ha in 2016.(2016 Gforest Health Report)
