Acorn & mast crop
Idaho deer rely primarily on browse, forbs, and shrub mast like serviceberry and chokecherry rather than oak acorns. Acorn habitat is minimal statewide; pinyon and other hard mast occur in limited zones. Mast is a minor variable in Idaho deer hunting.

Regional notes
Average for state's limited mast habitat.
Hunter implication
Mixed conditions — some areas with productive oaks, others without. Scout for the pockets that produced and hunt the travel routes between bedding and mast. Plots and ag fields still hold deer where mast failed.
